Sweet Devil

It's an improvement, but this really feels like a glass houses situation. Maeda had some reasonable points, but ultimately she's thorny too and doesn't have the grounds to harshly criticize everybody else

At the same time, i can see how people can forgive and forget that fast (i literally could not care less, for example), but ngl, i tought this manga would go the route of not forgiving for a couple of chapter, i ain't complainig but it feels weird? Anyway, let the author cook some more, this is still super early.

Was gonna let it build up again from chapter 51, but didn't know it was only 2 chapters away from being completed. Eh. Was an alright ending. I wish all ecchi bait manga at least had a sex scene at the end, like here.

Nice & clean.

She going turn into a female either teen or fully grown

They aren't just some random high school students. They are supposed to be college students studying cultural anthropology. Them not knowing something as basic as how basically every single culture in history till modern times fought with shields and spears IS fucking stupid.

sauce: "Breakthrough brought by forbidden master and disciple"

so masayuki is indeed in the same era but a bit in the future, i guess?

You do know that there is a sequel

It's gonna get real weird once Japan implements the law where authors have to use their real name.

Edit/ Since he is a pushover and his power originates from doing things that give him pleasure, he isn't turning the other girls away. Also It was stated in the beginning of the Anime and manga that the person who had this power before him had many wives which just so happens to be later summarized when the main character says that her can't do the same erotic thing with the same person in the same day.  HE NEEDS THE OTHER GIRLS AND THEY NEED HIM MAKING IT A WHOLESOME/INTERESTING ANIME/MANGA. The author of this Manga is truly talented and amazing.
