Miroku is a supernatural being manifested from rumors. Her rumors lasts years and she remains in the same form, meaning she is ageless. Think of it like the Easter bunny or tooth fairy or Santa Claus. She is a whole other being that exists differently from humans so it's difficult to try to rationalize her age compared to Koichi because it doesn't apply to her. They met when Koichi was a child, but she didn't start having feelings for him until he was 17, and she never engaged in anything with him until she fell in love with him, so I wouldn't say she groomed him either. She doesn't show any intentions of manipulating him or engaging in predatory acts with him, and their feelings for each other are somewhat wholesome. In conclusion, I believe that it's not a predatory age gap manga but you're free to think otherwise once you give it a try. <3
Is miroku in the body of a teen/ mentally a teen? Going off the synopsis alone it sounds like a predatory age gap manga but you can never be sure if you havent read right ? I know Kouichi is a teen im just confused, i dont like that sort of thing so anybody who has the time lmk!
