Hanaki Guriko hails from Kyushu.
He became infamous for defeating Suzuran's then strongest man Zetton, thus instantly elevating his name to the top of the food chain at Suzuran despite not initially participating in the Freshmen War. This earned him contempt from his fellow freshmen, and when they tried to make a move against him, he personally gave seventeen freshmen the beating of their lives, including the three finalists of the Freshmen War.
As Suzuran's strongest man, Guriko has participated in a number of fights, including matches against Kurosawa, Butcher, Tokio, Hana, Tsukimoto Mitsonobu, Muroto Zenmei, and his known rival, deceased Armament Head Kawachi Tessho, who he have fought a total of four times . After being defeated by Guriko, Kurosawa Kazumitsu becomes his right hand man, whom he nicknames "Kurosar".
He is normally an easygoing man and is always behaving in a jolly, trickster-like manner. He also rarely takes his fights seriously, often preferring to postpone them in favor of spending more time with his women. However, once a particular opponent angers him in some way (like hitting on his girlfriends or messing with his phone), Guriko turns into the Afro-Demon feared by everyone. When in his Afro-Demon state, Guriko goes into a blind rage and attacks everyone within the vicinity. Akutsu Kinji, who always seems to be around when Guriko is in this state, is often on the receiving end of Guriko's blind attacks.
More than a fighter, Guriko is also a womanizer extraordinaire, known for juggling his nine girlfriends at the same time - a fact which only angers the other Suzuran students. The fact that his girlfriends all know about the other mistresses and are okay with it only solidifies his womanizing prowess.
With a reputation for having immense fighting skill known by all throughout Toarushi, Guriko commands a lot of respect in Suzuran, despite his unwillingness to lead his own faction. Even though Guriko won his rematch with Hana (who was already in his third year), he was still able to convince the other students to accept Hana as their leader, stating that no man was more fit to rule Suzuran than Hana. The third owner of the Bullshit Buckle was given to him by Zetton after he graduated, which has been secretly passed down from the strongest of Suzuran since the time of Harumichi Bouya.Because of his antics, he is shown a few times to have symptoms of sexually transmitted disease.
Background & History
Hanaki Guriko is a native from Kyushuu who entered Suzuran in his freshman year. Nobody knew about Guriko as he rarely came to school and if he was there, he was usually talking to some girl on his cellphone. Suzuran first took notice when he took out Ujiie Jun and 9 other Housen students , this caused King Joe to call Zetton for a meeting regarding the incident.
He and Yonezaki were surprised when told that it was a freshman from Suzuran that caused the damage, thus leading the top dogs of Suzuran to inquire about Guriko. It wouldn't be long before Zetton and Guriko met. Running into each other on the rooftop. Guriko was on the phone with a girl before she hung up on him. With Zetton and Iwashiro Gunji listening in, Guriko and Zetton exchanged glances, where Zetton had an unpleasant feeling, this led to Zetton challenging Guriko, who was reluctant to fight. To anger Guriko, Zetton threw Guriko's phone off the roof, which contained every girls number he had met since moving to town. Guriko then entered his infamous "Demon Guriko Mode" and proceeded to fight and defeat Zetton .
