The review appeared that quickly? Back in my day...reviews appeared a day after they were made. Damn, they weren't lying when they said they updated. Feel free to check out my fanfics. I can't stop you but I can warn you -they weren't well thought out when written but a spur of the moment idea.
Akuma aren't quite mindless soldiers...only the level 1 ones are...they just have a certain loyalty that cannot be fully broken - altered by Cross perhaps but in the end, they go 'boom' if they break it. So yeah, I guess he can't be akuma since he doesn't appear to have that loyalty. But they talked about his eye evolving like one...so isn't he partially akuma?
Damn it Kanda, there's not much to talk about you anymore. Hurry up and find that 'man you must kill'.
