Actual MC development. No longer wears glasses, has asked Nagatoro to go out like the festival, motivated enough to actually improve in judo, is willing to act out of his comfort zone to improve his person, less shy, has improved his art, no longer sees popular kids as a threat, the list goes on.
Thank you Nanashi for not bullshitting the story with characters that never see development. I’m looking at you Komi-san.
