A master of Judo, everyone calls him "Matsushita 5-dan".
From what we know of Matsushida, he is a master of Judo but would rather learn to dance than fight, as seen whenever he's with TK he tries to copy his moves. He will do anything for beef udon or ramen, as seen when Takeyama bribes him with some to be on his baseball team. Also, Matsushida hates when people fight, so he's often seen holding back people who've lost their cool.
For a while Matsuhida goes missing but when he comes back during the climax of the twelve episode, he's slimmed down to much no one recognizes him.
According to Yuri, when Matsushida first arrived in Purgatory he taught everyone Judo locks which they then used on Angel's clones.
