Mashiba vs Sawamura:
I used to consider this a "everyone gets what they want" match. Mashiba kicks his ass, he gets the title, the crowd gets a bloodbath.
And I still think it kind of is, but I'm pretty sure Mashiba wouldn't be happy if he knew how Sawamura felt about the "beating". The thing is, he's a true sociopath... Mashiba, he pretends to be stone cold, but he cares way too much about things like looking bad, losing a match, or losing a fight.
Sawamura, he loses or gets hospitalized, and he doesn't think twice about it. He won't be kept up nights thinking "Dammit, Ippo beat me!" He simply does.not.care.
So in that sense, Mashiba lost everything. His title, his ranking, and his beat down was wasted on a guy who won't "learn his lesson".
