The main reason why I want him back is to help Azusa, I don't know why I can imagine Senzaki helping him ever so slight it. The new antagonist seems to be a pain in the ass, and Karino doesn't seem to have enough power, not with him being half-assed and not honest with his intentions (to protect Azusa of course), so we need a crazy mother fucker in the team, and Senzaki-Tatsumi team can be perfect for the spot, I would love them to support the main pair, as they're more fucked up honest with their shit as an opposition with our protagonists.
