Are we sure Kusanagi is.... Kusanagi, and not just alt palette stuff for Kyo?
It's cool if he is there, though! Kusanagi makes "Kyo" sound bloody violent, and that should be a decent return to "Body-GA!" Aragami/Dokugami shenanigans, maybe? (Why else would he exist? LoL. Kyo took all the moves he originally brought back...)
