You have arrived in the SWORD district. What kind of life you lead from here on is up to you. This is the story of you and Oya High School. Please, play as you like!
The 'O' of SWORD. The first leader of Oya High and a student in the Part-Time division. He successfully completed the tradition of "enduring 100 punches to become the leader," uniting the Part-Time division where thugs over 20 years old gather. His creed is "settle the score if you're messed with." While his academics and sports were average, he showed a genius talent for fighting. He transferred to Oya High to climb the ranks through brawling. Following a certain event, he had a one-on-one fight with Cobra, the leader of the S in SWORD (Sanno Rengokai), and lost. He temporarily lost his confidence, but after being challenged to a fight by Yosuke Todoroki, who transferred into the Full-Time division, he fully awakened and emerged victorious. He is interested in you.
