Kawachi Tesshou was the Sixth Head of The Front of Armament. He was headstrong, unconventional, and very often belligerent but nonetheless beloved by many even outside of the Armament, thanks to his high charisma, enabling him to solve many big problems with words and guts alone. He was a respected rival of Hanaki Guriko, who fought Guriko a total of four times. His leadership in The Armament was cut short when a drunk driver crashed into his motorcycle, killing him instantly. His death had a profound impact on Shougo, who later succeeded him as head. Tesshou joined the Armament's 5th generation two months after Togawa Shouta, at first they had a huge fight, but later they became blood brothers.
During his early days in the Armament, Tesshou was seen as a hothead, and a loose cannon who was a constant headache for his fellow members of TFOA due to his brash nature and knack for getting into fights with other teams without consent from leadership. This usually earned him disdain from his peers and superiors alike, especially Inada Genji who took it upon himself to reprimand Tesshou for causing trouble, occasionally knocking some sense into the young knucklehead who would one day carry the Armament on his shoulders.
Of all his reckless behavior as a young prospect, it all came to a head for Tesshou when his sister was harassed by a student from Suzuran High. Because of Suzuran's infamous reputation, Tesshou would decide to tread lightly, which in his case consisted of famously showing up to Suzuran's personal Train Station for it's students , known as "Crows Station" everyday looking for the guys responsible for messing with his sister. Due to the interference of his Boss Takeda Kousei, this incident was met with minimal casualty, and in the end Tessho was allowed to avenge the wrongs done to his sister thanks to long time Suzuran vets, Iwashiro Gunji and Zetton.
Before becoming the sixth head of TFOA, Tesshou took it upon himself to rear up the young members of the Armament, similar to what Inada Genji did for him in the past. He would take special interest in Murata Shougo, becoming a mentor and elder brother figure to him. Many of the lessons he taught Shougo would become the foundation of the seventh generation of the Armament.Tesshou also got a big rivalry with Kiyohiro Yoshimi who joined the Armament, both were choices to be the new leader, and they rivalry got bigger as Kousei got sick and had to retire before choosing who it was going to be. Kiyohiro showed a lot of strength and guts dealing with Yoshinari to defend Ogawa Chiharu, but after Zeniya's vice-president Hiwatari Kei bowed to Tesshou to apologize for the matter, Kiyohiro then realized that Tesshou should be the next leader. Tesshou said it was bullshit to let an outsider decide who was the leader and they decided it with a fight. Tesshou became the 6th head of the Armament after that.
