Mashiba is so tsun haha. Tanaka won't have it easy, but her being mature certainly helps. It's still pretty obvious that he acknowledges Ippo. From earlier chapters we knew that Mashiba scared all the boys (Ippo experienced it firsthand xD), him ambushing them is knew, tho.
Imai vs Hoshi literally came outta nowhere, even tho it makes sense that the West Japan Rookie King Tournament Winner would make it to the Champ. I'll gladly take this match between two power types who finish their fights quickly.
