Ebisu Kouichi, also known as Bisuko, holds the position of the third head of the Kuzugami Group in the Manji Empire [1]. He is also the boss of Tenzen High in Tokyo's Machida region, having led the school since his sophomore year.
Plot
Middle School [2]
During his senior year in middle school, Bisuko demonstrated his dominance by handily defeating twelve individuals from Nishi Mid who had awaited him at the station. This act, followed by his nonchalant reading of his beloved manga "Urakin" while sitting atop one of the defeated, showcased his fearlessness and strength.
The Manji Empire
Bisuko showcased his power by single-handedly dispatching Himekawa Kei, the leader of the Front of Armament's Flying Column and the KKK Demons [3]. This incident took place when Kei and his group journeyed to Tokyo, aiming to provoke Hiruma Yuushi, another member of the Manji Seven.
Bisuko was forced to go to Toarushi himself to collect Hiruma, who had went to get revenge for his defeated friends and Manji sub group, the Ikeshima Brothers.
In search for the T.F.O.A hideout, he met Hana Tsukishima at a restroom. After helping Hana with his toilet troubles, he stumbled upon Suzuran High and tried to remember where he had heard of the school before. Bisuko finally arrived at the Armament base, where he found Hiruma had fought to a draw with the Head of the E.M.O.D, Maekawa Muneharu.
Bisuko, along with his fellow Manji seven members would fight the seven men from Toarushi who came to Tokyo to finish the long grueling war with the Armament and the EMOD. He is the last to fight and he defeats the Front of Armament's head, Murata Shougo [4].
Returning to Toarushi, Bisuko returned an umbrella borrowed from Hana and engaged in a concealed challenge with him. The intense showdown between the two was closely contested, resulting in Bisuko's slight triumph. The camaraderie formed between them persisted, even in the face of rumors about their battle outcomes.
Even though Bisuko barely won his fight with Hana [5], rumors still spread around his hometown that he had actually lost. Although initially people dismissed it as rumors, but when Manji strong men, Karashima Jun and Shibaki Masami heard, they believed Bisuko might have actually lost as they both have experienced Hana's strength, as well as Bisuko arriving in Machida with a messed up face. This led to people in Machida believing Bisuko really lost. This initially didn't bother Bisuko at all, considering it as an opportunity to shed his "Boogie man" persona in the eyes of everyone in town.
However, after a couple of goons gunning for him catch wind of his supposed defeat, they decided to target Hana instead, this led to Bisuko taking care of all of the thugs personally [2]. Stating that he couldn't introduce any of them to him.
His friendship with Hana will last a lifetime.
Fights
Bisuko is considered the strongest fighter in all of Manji. Being the strongest man in the strongest and largest gang in all of Japan, he is considered by most to be the strongest delinquent of his era.
