It's honestly really annoying how few people recognize a traditional "bancho" outfit. Hell its not even the first time Osonada has been drawn wearing it. Potato is far from the only character who dresses like this, guys.
That stare from Rokudou gives me chills every time.
Kung-fu does come from every day life. But her every day life is that of being a delinquent so that's how she teaches. Also she eased him into the hard stuff unlike Iinuma or Ranna.
