Okkotsu Yuta is such a funny character cause you're initially introduced to him as 'super powerful upperclassman studying overseas' and you go 'ah yes, I recognize this trope- this is a Secret Tool that will help us later, he will return an opportune moment when things look most dire to aid Our Heroes' but then you watch his prequel movie and realize it's all about him ending his toxic comp het relationship with his childhood best friend('s ghost) and getting what amounts to a magical divorce and then you realize he is a giant loser (affectionate) and actually he's not overseas training, he's off doing some 'eat pray love' white girl shit and trying to Find Himself post divorce, and you think "well good for him"-
AND THEN when he finally shows up in the story proper he's back in the EXACT SAME TOXIC COMPHET MARRIAGE he spent his prequel getting out of, because it turns out said marriage was the source of his Terrible Cosmic Powers and not only is he not here to help Our Heroes, he's gunning for the Main Protagonist specifically because said protagonist (accidentally) cut off his side piece boyfriend's arm and so he Must Die, and no it turns out that Yuta did not in fact learn anything from the events of the prequel about his attachment issues, co dependency, and letting go, and he fully intends to weaponize his toxic marriage to avenge his boyfriend in a conflict that could maybe level all Tokyo but who cares about that? A bad thing happened to Someone He Loved and it's Overreaction Time Baby.
Anyways, Okkotsu Yuta is a loser (overwhelmingly affectionate) and I support him 100%.
