Hanazawa Saburou AKA Zetton is a former student of Suzuran All-Boys High School who was a senior and one of Suzuran's leaders during Hana's first year. A middle school junior of Crows protagonist Harumichi Bouya, Zetton moved to Toarushi from a different town and entered Suzuran High as a first year. After reuniting with Harumichi, Zetton participates in his generation's First Year War by first beating Class F's Aikawa Toji, he then advances to the final round against Katou Hideyoshi whom he defeats to stand at the top of all of the freshmen in Suzuran.
He later challenged his old friend Bouya, to prove to his peers that he wasn't just his loyal dog, a fight which Zetton ultimately loses. When Bouya left Suzuran, Zetton was recognized as the school's strongest man.
Zetton is a lone wolf and a fierce combatant who accepts any challenge, his strength commanded a lot of respect in Suzuran and Toarushi. He's very eccentric and carefree but displays extreme loyalty to his friends, frequently spouting words of wisdom to those around him. One of the The Four Kings in his generation, consisting of himself, King Joe of Housen, Nakajima Shinsuke of the Kurotaki Alliance, and Takeda Kousei of the Front of Armament. During their rise to power, three of the Four Kings were targeted by the Manji Empire's Kuzugami Tatsuo, after Tatsuo took out Takeda and Joe, Zetton was the last to fall against Tatsuo before Bouya ultimately beat him.
Hanazawa's third official loss would come during his sophomore year, when he lost to the freshman Hanaki Guriko,thus ending his reign as Suzuran's strongest man, regardless he still remained the top of his class and is considered one of the greatest men in Suzuran's history. Second owner of the Bullshit Buckle worn and secretly passed down by Harumichi Bouya, which Zetton later passed on to Guriko when the former graduated.
Kikyou MidHe went to Kikyou Mid with Bouya Harumichi and was said to be the closest person to him in the school. When Hanazawa was in middle school.
Before meeting Bouya, he wasn't quite a delinquent, wasn't very noticeable at all and was pretty well mannered ,
One day, Nemoto, the school's gym teacher who students nicknamed Ultraman, called Zetton out in front of the entire the school. He then accuse Zetton of hanging out at downtown the night before. Zetton had no idea what Nemoto was saying but Nemoto wouldn't listen. Nemoto then suddenly shouted at Zetton which later caused Zetton to headbutted the gym teacher right in the nose . He then became the school's biggest star after Bouya and was nicknamed Zetton for toppling Ultraman (which is Nemoto) .
He is later seen with Bouya listening to a couple of fellow students who were telling Bouya that they got into a fight with another middle school and asking if he could fight for them. Bouya yells at them and he and Zetton leave.
Later after the school went to war with each other, the other students are whining that Bouya won't fight for them and that he might be scared, which made Zetton mad and he yells at them calling them cowards and embarrassing.
He later went to talk to Bouya and tells him about what happens and how he yelled at the others for whining so much. Bouya tells him that he is going to Hattou Mid to settle the fight. Zetton calls him insane for going there alone.
They both go and Zetton was nervous at first but by the time they got there, he had settled down and felt like they could win just by the two of them. They were completely surrounded and he watch Bouya fight Hattou Mid's boss, Kawaji Hideo. When Bouya won, he told Zetton to get ready to run because all of the Hattou guys would be mad that their boss was defeated. Later after Bouya came back from his suspension, he and Zetton were talking on the roof before Bouya leaves the school .
Suzuran's Freshmen WarZetton is first seen in Suzuran when Akutsu saw him surrounded by Hotta and his group . When Akutsu came back, he saw that all the second years were beaten up . He is later seen by Akutsu, crouching over Sagawa making Akutsu think he stabbed him . Zetton then ran to the rooftop to tell Akutsu and the rest of the people up there that he didn't stab him . Bouya heard the screaming and looks at what is happening and instantly recognizes Zetton. Bouya told the rest of his friends of how Zetton got his nickname .
Zetton told Bouya that he will fight in the Freshmen War and that he will stop the other freshmen from reaching him. Bouya tells him that he will leave it to him . When he was leaving he was stopped by Hiromi who asks him that if he wins the Freshmen War, will he fight Harumichi. He thinks about it and then tells him no . He defeats the strongest freshman in class F, Aikawa . Days later he, Iwashiro Gunji, and Hideyoshi met each other accidentally in the bathroom where they discuss how they will end the Freshmen War. Hideyoshi calls him Bouya's dog and tells him that they won't lose to him which make Zetton mad . A couple of days later, he fight Hideyoshi to determine the winner of the Freshmen War. Hideyoshi and Zetton had a back and forth fight and ultimately Zetton wins . He tells Iwashiro who was the witness of the fight to give him the six buttons which makes him the winner of the Freshmen War. He then told a stunned Iwashiro that he is not a dog.
Fight With BouyaAfter winning the Freshmen War and missing a day of school, he went to the roof to challenge Bouya. He insulted Bouya which prevented Bouya from fight calmly and giving the advantage to Zetton . Hearing encouragement from the crowd that had gather to watch the fight, reminded him of his victory against his gym teacher in middle school. He then got the feeling that he could beat Bouya . He thought he had him with a kick but Bouya caught his kick and punched him hard which sent him flying and knocked him out . After the fight he became more loyal to Harumichi.
Trip To The OceanWhen it was heard that Bouya, along with Kunou Ryuushin and Tatsuya Bitou, went to another town to take on the Snake Heads Gang, Zetton, along with Hideyoshi, Gunji, Masa and Yonezaki go to look for Harumichi. When the group interrogate a few people, they learn that the Snake Heads are preparing for a fight against P.A.D at the Nakazaki factory .
While running to the Nakazaki factory, Masa collides with Tamasu Tsuyoshi. When they learn that Tamasu is with P.A.D, Tamasu helps them find Bouya. However, after not finding Bouya, Tamasu led the group into hiding . When they heard P.A.D were making their comeback, the group got ambushed by more than 100 Snake Heads members  and Zetton fought against Mayumi Tetsuji. Despite hurting Tetsuji, Zetton lost the fight .
When Zetton escapes with Hideyoshi, Masa and Yonezaki, they find Gunji who escaped in a different direction. Gunji informs them that Harumichi, Ryuushin and Bitou are going by themselves to take on the Snake Heads once and for all at the Nakazaki factory. When they wait outside the Nakazaki factory for the signal, the reinforcements from The Front of Armament arrive, prompting Zetton to run ahead to join up with the Suzuran reinforcements and take on the Snake Heads outside the warehouse .
Changing of The Guard
After the war with the Snake Heads, Zetton and his freshmen peers returned home to Toarushi where the generational shift had begun. As rumors about the 4 Kings and Suzuran seniors swirled, Zetton himself commented on what he thought was "The ending of an Era, and the Beginning of a new One." Zettons premonition was correct.During the war between Housen and the Kurotaki Alliance, a band of thieves made their presence know in the town. Led by Kai Yasunori, this group would shake up the foundations of each ofthe newly appointed 4 Kings. Kai's group had robbed or jumped or harassed members of T.F.O.A, Suzuran, Kurotaki, and Housen. Each group, as well as the police, were out for their heads. After a second run in with Zetton's classmate Gunji which resulted in and extreme ass whooping, Kai attacked Armament member Shinnosuke out of rage. As Zetton left the train with Bouya on their way to school, he saw King Joe for the first time. Later realizing who each other was, they each ran to find the other. Giving up on the search Zetton eventually found himself in a Mexican Standoff with the Front, Housen, and Kurotaki over Kai who was held up in a building talking to Armament Vice-Head Yanagi Shinji.
At this point the 4 parties considered Kai's situation irrelevant and were more interested in seeing which of the new generation leaders was the strongest. The matchups were King Joe vs Takeda Kousei and Zetton vs Nakajima Shinsuke. Unfortunately before any of them could fight it out, Kai had left the building and challenged them all after attacking Yanagi. Kousei enraged, beat Kai to the point of hospitalization . This left each of the other Kings noticed that Kousei was a dangerous and strong opponent.
After hearing the news that King Joe and Kousei had fought, Zetton traveled to Housen territory in order to talk to the Housen Head about it at Johnathan's, a restaurant were these two would meet up on several occasions in the the future. Zetton asked why King Joe didn't challenge him considering himself as the champion of the freshman for winning the Suzuran first year war. As Zetton was about to leave King Joe questioned why he didn't ask who won. Zetton replied saying he didn't care who came in third place, suggesting that He and Nakajima Shinsuke were the top 2 of the class.
Enter Kuzugami Tatsuo
After beaten by members of each of the towns 4 contending forces, the punks who had been running with Kai decided to get revenge on the newly appointed Four Kings. They hired Kuzugami Tatsuo, rumored to be the strongest delinquent in Japan and head of the Manji's Empire's Kuzuryuu group who was hiding in Toarushi. Kuzugami left the Manji Empire after being choosen over by Inou Hidejirou from the Kuzutora Group. For 400,000 yen, Tatsuo agreed take out each of the big name freshmen; Takeda Kousei, King Joe, Nakajima Shinsuke and Zetton. Tatsuo attacked and defeated Takeda Kousei and most of his Armament team . The next day he destroyed King Joe and Ujiie (the latter with one shot) . Zetton went to visit both King Joe and Kousei in the hospital. He told Shinnosuke and Genba that he would be the one to get payback for what Kuzugami did to his rivals .
Zetton began his search for Tatsuo as soon as he left the hospital, but not before testing his strength on a nearby telephone poll. Eventually he found his target along with his only remaining underling Toshio. Zetton jumped down from the wall, (A feat he would end up breaking his foot from attempting after he graduated) and proceeded to lecture Kuzugami about fighting two already injured men. Tatsuo was of a different mindset . When Toshio tried to convince Kuzugami to leave the town he ranted that there was no one left to go back too. He asked Toshio why he was chosen over and Zetton gave him the answer Toshio was to scared to give. That he was empty inside and all he could do was fight. Enraged at Zetton's words, Tatsuo charged at him .Zetton drew first blood with a spining reverse kick that dropped Kuzugami to the ground. Zetton's next combination was mostly blocked by Kuzugami and countered with a strong straight right hand that sent Zetton to the floor leaving him bleeding profusely from the nose . From there on the fight was dominated by the Manji thug. Zetton tried to tackle Kuzugami to the ground but was yoked up and suplex-ed on his back and neck . Tatsuo continued to whale on Zetton until the Suzuran freshman was down for the count .
After losing, Zetton apologized to Toshio for not being able defeat Kuzugami and change his outlook on life. He told him to remember the name Bouya Harumichi because he was the only man around who could stop the Manji Monster. Zetton was hospitalized after his lose.
Zetton met with Toshio once again when it was time for Bouya and Tatsuo's final showdown. When the two began fighting and Kuzagami gained the upper hand on Zetton's senior, he sensed that Tatsuo's underling wanted his own aniki to lose. Zetton gave Toshio words of reassurance. Saying that Bouya would definitely win. When questioned by Toshio for about his confidence in that result Zetton replied "If Kuzugami Tatsuo is the strongest man, then Bouya Harumichi is the greatest man, and his greatness wont lose to his strength" .
After a long battle Zetton and Toshio watched as Bouya had defeated Tatsuo . Zetton carried his senior home realizing that Tatsuo did have at least one treasure in his vault.
Dealing with the FrontEarly in his sophomore year, Zetton was forced to handle a delicate situation between Suzuran and The Front of Armament. Future Front Head Kawachi Tesshou's little sister had been abused by two Suzuran students. After several failed attempts to find the men responsible, The Armament's current head Takeda Kousei had came to Suzuran's doorsteps himself to resolve the matter . With Hideyoshi, Gunji, and Masa all absent from school Kousei asked Yonezaki to get Zetton so he could talk to him. After making his signature grand entrance, (and hurting himself)  Zetton and Kousei talked about the situation. Zetton questioned Kousei's demands and not until Tessho let word slip about his sister he was reluctant to adhere to the Armaments request. Zetton had Yonezaki get Takamizawa. Once he arrived Zetton told everyone watching to go back to their classrooms.
Before exiting he asked the whereabouts of the second student involved. When he let himself be known, Zetton made quick work of him. Unleashing a thunderous left kick straight to the guys chin, and sending him flying in Suzuran's courtyard . He then left after bidding Takeda farewell.
After this incident with the Armament, Zetton and his fellow upperclassmen would start a tradition in Suzuran, betting on the freshman battles. After hearing the list of potential winners from Akutsu Kinji, the Suzuran sophomore's bet his money (500 Yen) on "other" rather than Butcher, Kurosawa, or Tokio .In the midst of the Freshmen War, Zetton and Yonezaki sat down with Housen Head King Joe and his right hand Ujiie Jun. Apparently a Suzuran freshman had beaten Ujiie and 8 other Housen Hitmen, a feat that would be nearly impossible for both Zetton and Joe .
Following the meeting with King Joe, Zetton walked to the roof with Gunji filling him in on the amazing first year that joined their schools ranks. Moments later Zetton and Hanaki Guriko would meet for the first time. Guriko passed Zetton giving him a cold chill and a sense of extreme strength. Once Zetton got confirmation on who was standing in front of him he made his move. A High kick was dodge but Guriko shocking both Zetton and Gunji. But the future demon king dropped his phone in the process of dodging.
In order to get Guriko to fight him seriously, Zetton picked up the phone and hurled it off the roof. Enraged, Guriko leaped into the air (a signature move of his) and the true fight began. Zetton landed a bunch of big kicks and punches but he could never bring Guriko down. Zetton had received his third loss . By the end of the day the word had spread throughout town to each of the Four Kings. With Zetton's defeat the town's power balance had been disrupted.
Enter Tsukishima Hana
Even into his 3rd year, the power balance had yet to be restored following Zetton's loss and huge changes began to unfold around the town. The collapse of the Kurotaki Alliance creating a lawless area in the eastern part of the Toarushi, the infighting in Housen and Suzuran's constant battling between factions continued. Only T.F.O.A had remained constant throughout but they too would soon experience their own major change.During Hana's Freshmen War, Zetton watched as the young freshman declared he'd one day rule over the school. He applauded the youngster and told him he was rooting for him . Then he asked for Hana's name to instill it into his memory after watching him beat his opponent (Katsuhiro).
The next day he watched as Hana beat Amachi. The following afternoon he would finally meet Hana on Suzuran's rooftop. Zetton tried to sneak Hana with a strong right hand, and continued his onslaught with a 2nd left, and powerful kick that Hana commented would have killed him if he hadn't blocked it. Hana then unleashed his deadly uppercut in retaliation which Zetton blocked using both forearms. Zetton was impressed by Hana's abilities. Hana was dumbfounded by his senior's ability to go from fighting to calmly complimenting him.
After their little skirmish, Zetton and Hana had a talk about their beloved schools history. Zetton told Hana about one of the three men to ever defeat him, The towns strongest Man, Hanaki Guriko. Although most of what Zetton said about the Demon King was untrue, he sent the chivalrous Hana after the alleged evil man standing in his way of changing Suzuran . Zetton as well as Yonezaki knew that Hana would lose to Guriko, Howevere, they wanted to make sure Hana knew what level of strength he would need to reach in order to obtain his goal of being Suzuran's first head.
Guriko met with Zetton and Yonezaki on Suzuran's roof the day after his altercation wih Hana. Asking why he sent the child after him. The two (mostly Yonezaki) lectured Guriko about his standing as strongest and what it would mean for Suzuran's future and their underclassman Hana. The two of them would have to be the ones to move Suzuran forward whether he liked it or not . They implored that he need to help their junior, Hana to achieve his goal. Guriko took these words to heart as he would indeed help Hana gain of next year's Freshmen Champ Daizen and in their senior year giving a grand speech after the 2nd battle between the two.
The War with Housen
In the first semester, Suzuran went to war with longtime rival school Housen. After a fight between each of the schools students in an alley, Hideyoshi's best friend and number two of his faction, Masa was attacked with a bat by Urano of Housen after he himself was left bloodied with a gash over his eye.
Hideyoshi's vengeance was quick and merciless. He attacked Urano as well as the other six Housen students who were there with him. The War had begun.The next day, on his way to school Zetton was met by Big 4 counter part and head of Housen, King Joe. Unbeknownst to him King Joe ordered the ambushing of several Suzuran seniors and sophomores (including, Gunji, Yonezaki, Guriko, and Kurosawa) King Joe led Zetton underneath the bridge (where many notable fights in Crows and Worst have taken place) and the two were immediately met with two Housen graduates Uchida and Kadoya who had themselves fought Joe upon his entering Housen. It is not stated as to whether he loss or not but they did leave Joe with the iconic scare on his nose.
Zetton asked why not fight him one one, realizing that he was about to be jumped. Joe understanding that dealing with Zetton, Hideyoshi, Gunji, Guriko etc would be to troublesome said he was going to take this opportunity to "deal" with Zetton.
Zetton asked if Joe was scared to fight him on on one. Joe said that their viewpoints on the situation was different with Joe being a head and Zetton simply being a strong fighter with no responsibilities.
Hanazawa defeated both Uchida and Kadoya, who were both armed with lead pipes they used against him . The battle was long and ended with an exhausted Zetton sending a flying kick upward into Kadoya's chin just before the Housen graduate could block it. King Joe commented on Zetton's impressive showing and struck him in the head with one of the lead pipes . The Housen Head had successfully "exterminated" (as Katsutoshi put it) Suzuran "Space Dinosaur". At least for the time being.
After he and his fellow upperclassman were taken out, the war between the two school escalated throughout the town. The all out war raged on for 3 days. 47 people were injured with 16 sustaining serious injuries like bone fractures. Eventually the police got involved and the two schools were temporarily stalemated . Then a phone call between King Joe and Hideyoshi decided the time and location of the wars grand finale. 5 AM the following morning at the Monster's Forest.
Just after the phone call, Hideyoshi met with Zetton, Gunji, Yonezaki, and Masa. Gunji and Zetton were enraged at the suggestion they sat out of the battle. Hideyoshi told Zetton that he believed Joe attacked him so that he could fight him alone like he did with Takeda in their freshman year. Hideyoshi pleaded to his friends to let him handle the war shocking all of them with his out of character plea .
The day had arrived and students from both schools assembled for the finale. Zetton came to see his Suzuran brethren finish the battle and potentially, fight himself. Former Kurotaki President Nakajima was chosen to determine the war's structure. 5 on 5 endurance battle featuring 2 seniors, 2 sophomores, and 1 freshman.
Zetton watched as his underclassmen took care of business. Hana defeated Housen's Matsuo Daisuke with his soon to be legendary uppercut . Then Kurosawa bested his middle school rival Mashima in what turned out to be a mismatch . Soon after, Butcher fought with his long time nemesis and Moonlight Brother Tsukimoto Mitsuyoshi, beating him with a strong back throw . With Housen already lose, the seniors were set to duke it out. The arrival of Guriko paired him in the senior bracket against Tsukimoto Mitsunobu (Taking Zetton's place) Despite Guriko not wanting to fight, Zetton and Butcher comically threatened him as they were annoyed that Guriko was with a girl before arriving at the Monster's Forest. The Demon King knocked out Mitsunobu with his patented high kick .
Then the last battle between Joe and Hideyoshi took place. It was a long and brutal fight. Their noses were bleeding, teeth broken, and their faces all swollen. There was not a sound to be heard except for the yelling and groaning of those two. Zetton watched in silence as well. Finally someone was brought to their feat about to lose. Katou Hideyoshi's stood once more forcing Joe to land the finishing blow . Joe was then stopped by Katou's best friend, Masa and the fight stopped. Angry at Masa interference, Housen charged at Suzuran. Suzuran charged right back and it was an all out war.
After the 5 v 5, Zetton and the rest of Suzuran went back to school, where Zetton caught up on his sleep.
The End of An Era
Soon after Suzuran's war with Housen, a huge change would befall the the town. Takeda Kousei head of the Front of Armaments 5th generation, was forced to retire due to illness. On the day Kousei was leaving, he was met by both King Joe and Zetton. They bid him a farewell giving him gifts. Joe's gave his and Nakajima's presents, envelopes with money in them. Zetton gave a bag of porn as he is jobless and had not money to give for the operation. Kousei was deeply grateful to his rival kings for their concern and he left for Tokyo after saying Thank You.
There was a group of guys called the 'Big Four'. Nakajima Shinsuke left the town. Hanazawa Saburou called 'Zetton' was defeated by Hanaki Guriko. Kanayama Jou known as 'King Joe', took advantage of the the fight with Suzuran to pass down the throne of Housen to the Moonlight Brothers. And the last one, Takeda Kousei had declared his retirement from the Front of Armament. It tells the end of one era and at the same time, the curtain of a new era is raised!
The ChallengeButcher, the leader of the largest faction at Suzuran, who had gained more power after beating Mitsuyoshi, went to the rooftop to find Zetton relaxing in a rubber bath tub. He tells Zetton that he plans to move to the rooftop once he succeeds and that he is fit to be leader of Suzuran as Guriko, despite being the strongest, is hopeless, Kurosawa is unpopular and Harada only has brains.
He tells Zetton that he must have a match against master, stating that rumors will spread if they didn't and that he wants him to accept his challenge. Being serious in his intent, Zetton was naked changing into his clothes. After changing, Zetton tells Butcher that it is fine, and that it is his duty to accept anyone's challenge at any time.
Zetton easily beats Butcher . After knocking him out, Zetton states that Butcher did his best, but is 10 years too early to beat him. After looking at Butcher on the ground, Zetton remembers that Butcher and himself were standing in the same place as the time Bouya Harumichi beat him in his freshmen year. Worried Butcher will get burnt out in the sun knocked out, Zetton puts him in the bath tub without his pants on, much to the shock of Butcher when he wakes up.
Four Way Match
With the Seniors all retired from the front lines, Suzuran went to war with the Jet Black Scorpion. sophomore's Butcher, Kurosawa and Tokio were the original targets of Scorpion heads Kamata and Tahara due to their history with them. When one of Guriko's girlfriends is attacked by a JBS leader and Renji is jumped with pipes, Hana and Guriko joined the hunt for Scorpion's. It was a four way match. The seniors watched from the rooftops and placed the usual wager. Masa picked Butcher and his army as they had the most numbers. Gunji picked his successor Tokio. Yonezaki put his money on Guriko and Kurosawa. Finally Zetton placed his bet on Hana and his freshman followers. Each bet was for 500 yen. Ultimately each faction played a part in the dismantling of the Scorpion. Butcher found the mole in his Army (Ban) and dealt with him accordingly. Tokio and his Harada Faction cornered Kamata and his team and destroyed each of them, with Tokio taking out Kamata one on one. Kurosawa found the man responsible for the attack of Guri's girlfriend, with help from his future Suzuran underclassman Nakamura Ginji. Fujieda was meeting with Housen's Moonlight Brothers. When Guriko Knocked him clean out with one of his famous kicks sending him flying into a shop window. Guriko also knocked out Mitsunobu with his presence alone.
Zetton's pick, the Hana-Gumi along with Takumi and Yamaguchi Zenjirou found Tahara and 27 underlings. They freshman obliterated the JBS forcing Tahara to run away in fear. Hana then convinced Tahara to fight him one on one and defeated him with a judo throw. With this the battle against JBS and Suzuran was over. It is unknown who actually won the bet.
Suzuran's 27th Graduation
With Zetton's peers all set up with their after high school plans, the Suzuran Senior took some time to think about what he wanted to do with his life. He decided on becoming a teacher and returning to his beloved Suzuran.
Towards the day of the 27th senior class graduation, sophomore Kurosawa informed Yonezaki, Masa, Gunji and Hideyoshi that Shirai, a former senior who Zetton knocked out with his trademark kick, is planning to gather his friends and as they Kill Zetton. The seniors tell Kurosawa to keep the information to himself and tell Guriko to show his face at the graduation. Masa asks Hideyoshi if they should tell Zetton, in which Hideyoshi replies that Zetton shouldn't be thinking about anything else apart from his university entrance exam. Hideyoshi turns to the others and says that they will take care of it themselves as it will make the graduation more entertaining.On the day of the graduation, Akutsu Kinji gives Zetton a photo of containing Zetton, Yonezaki, Masa, Gunji and Hideyoshi together in their sophomore year. A nostalgic Zetton prepares himself to say farewell to Suzuran. Unknown to Zetton, the other leading seniors intercepted Shirai and 10 of his followers carrying steel pipes near the Shinto Shrine.
After the graduation ceremony, Zetton finds the others outside asking why they skipped their graduation ceremony. Masa says they went for a walk, to which an angry Zetton says they were up to something as they are carrying bats. Gunji says that since they missed the entire thing, might as well get some food together. Zetton stops and says that this is the last day the five of them are gonna meet together at Suzuran and that next time they are here, they will be outsiders. Zetton says that something is missing. after reminiscing of their time at Suzuran, Hideyoshi turns to the others and says that meeting you guys after coming to Suzuran is the best thing that ever happend to me. you where always helping me out. Thank you. The others express they share the same sentiment and a crying Zetton tells Hideyoshi he stole his lines.
While contemplating what food to get by throwing a can in to a bin, Zetton suggests that they should determine their future on the throw. If Zetton gets it in the bin, their story will shine from now on.
Two years after graduating from Suzuran, Zetton went for a jog and got distracted by a chick in hot pants and got lost.
While running 40km back to Toarushi, he bumps into Suzuran seniors Tsukishima Hana and Tominaga Toranosuke. When Tora asks Zetton how his studying is going, a cheerful Zetton became annoyed and tells them that he took the academic ability test last week and that the work to get in hard. But he won't back down and he will get the passing grade. Zetton notices that Hana is wearing the Bullshit belt and Hana tells him that Guriko gave it to him at the end of the last year, thinking he would graduate.
Zetton laughed about Guriko repeating his last year and that the belt belonged to his senior, wko passed it on to him, who then gave it to Guriko before he graduated, and now Guriko has passed it on to Hana. Zetton says the belt has a nice list to it and that Hana should not worry about being the strongest, but to be the greatest man . Zetton then farewells Tora and Hana.
Towards the end Hana's senior year, Zetton passed central exam and then did the entrance exam for a University up in Tohoku .
Zetton has also been training every day to get back in shape. While on his run, he Zetton came across a brick wall he used to jump off when he was younger.
