The Anime Lad
Kenichi is routinely bullied and has few friends willing to defend him. Meeting Miu leads him to the dojo where she lives with six martial arts masters. He hopes their training will help him survive school. They respond with hard-core instruction and an enthusiasm that should concern him. Self-defense begins through the repeated discovery that masters define reasonable effort differently.

Kenichi begins as the kid everybody picks on, then Miu leads him to a dojo packed with six martial arts masters! He does not receive easy strength.

Father's Basement
The marketed description spends too much energy reducing Kenichi to a wimp and Miu to motivation. The training premise is better than that framing. A bullied student enters a dojo run by six masters because he needs enough strength to survive school. His ordinary vulnerability gives every hard lesson a concrete reason to matter.
