So who did he have sex with? The fox (which is cheating) or Akiha?

Both lol

Well since the fox and Akiha are two completely different beings, he cheated on Akiha. What a jerk (╬￣皿￣)凸

How’d he cheat, they established that Akiha was just being more honest because Yukuri asked him to

What the fuck you on about. The guy fucked the fox while he was still possessing Akiha. And the fox and Akiha are not the same.
