"oh by the way, i forgot to tell you there's a fallen god or something somewhere 'round here. not that it'll matter much because you're so strong anyway that you probably can german supplex him"
I don't think that fallen god and this Akuya Shinji are the same person. Maybe this Akuya Shinji was the one who made her scared of men? If I recall correctly, she did say that at chapter 1 or so.
