So, to start out with, after reading 82 chapters, there's one thing that keeps creeping me out that never seems to get better: the female demon lord encouraging the young, naive male lead into various acts of flirting, playful love and sensual contact (not outright groping, but stuff that is definitely too mature for the MC). It comes across as grooming.

"But it's not real... blah, blah, blah!" Look, there was absolutely no need for the hero to be that young. There was absolutely no need to, after a one year time skip, not have the hero physically grow up at all.

Furthermore, unrelated to the fictional grooming: there was absolutely no need to have nudity in a manga with a main character designed to appeal to children. This feels like a manga meant to draw minors in and introduce them to sexual themes that even adults often avoid (like vore). It's approaching IRL grooming or child abuse.

So how does the rest hold up?
Surprisingly well. The plot and world building are interconnected and the latter is especially well utilized. The characters are interesting as well.

But there's not much wisdom. In fact, there's the opposite, which makes a lot of the dialogue and narrarion a slog due to regular nonsensical conclusions made from a confusing observation of a given situation.

The art is interesting, as the artist clearly struggles to draw anatomy from the hips down (especially before the first 30-40 chapters), but is pretty good otherwise.

Had there not been any nudity, or had the character been a couple years older (not designed to appeal to young kids), I'd have just pointed out the nudity as a warning. But as things are, I can't recommend this in good conscience.

I won't rate this.

I stopped reading as soon as I realized how offensive the underlying concept is. It's what a demon would probably actually do, but yes, a demon building a relationship of trust and emotional connection with an overly innocent 13 year old?? Eventually slowly teaching him sexual things in order for them to be able to do so in the future as his wife 😶 isn't this the very definition of CHILD GROOMING.
It is NOT okay to ROMANTICISE such a problematic thing.
How on earth do these kind of manga even get published. Ah but come to think of it even redo healer got published.

The MC is tossed out of the hero group and is then picked up by one of the 7 demon lords.
The MC is OP as fuck but the story isn't focused around him fighting things. Most of the story focuses around character relationships as the MC tries to do his best for his Onee-san (Demon Lord). The characters are fun to watch and things are well paced.

Overall 4/5 - It doesn't have anything outstanding going for it, but it does everything well enough to make it above average.
