Keep It Playful

[originally on ao3]

Isagi Yoichi is no prodigy in Jiu-Jitsu, but a result of pure hard work. That's what makes him a tricky opponent to fight. He is the top athlete in Ichinan High and Chigiri's fated and sworn rival, the rest is history as to why there's a hint of badblood between Rakosute and Ichinan as long as he could remember. And it must be fates laughing at them when they represent each school.
