Kenichi is a timid, bullied high‑school student who rarely has friends to back him up. He needs a spark to keep him afloat, and that spark comes in the form of Miu, a striking, confident girl who accepts him and lives with six martial‑arts masters at a nearby dojo. Whether fate or a crush draws him there, Kenichi embarks on an intense training regimen under the masters’ tutelage, hoping the rigorous lessons will not only harden him physically but also help him survive another day at school, and perhaps win Miu’s affection.
