Honestly though, if I was in his shoes I'd take it.
Going from a 50+ year old man who's probably going to have health issues in a few years (if not already) to a 20 or so year old beautiful girl seems like a no brainer.
I prefer if it's kept the same as the source material since there might be references to it that wouldn't make sense if it's localised. Also bonus points for sounding like Pikachu
Don't you just love it when the overpowered MC lets himself get walked all over by minor villains because he's "the good guy". Truly peak storytelling.
