I'm saying this again but I REALLY hope that it's a brainwashed Akihito, because first if isn't, that would mean Asami is a big fool for not recognizing him. And second, it would be more interesting than having Akihito prisonned in room and being the sex slave of other antagonists perverted. Asami would have to be very cautious in this very delicate situation (pun unintended).
So far I found the preview
