It might contain a bit spoilers.

I started this manga because of its horror and mystery genre. I thought this story was about the fight between the villagers and the outsiders. However, it was completely different in an interesting way.

Leaving the sexual substance or service aside, the mystery in the story is actually fascinating. The MC developed from being a normal to special thank to the darkness of the island itself.

That's why I give it 8/10 because the art is being drawn very beautifully and the story hasn't finished so it's too early to judge the plot.

P.S: I'm not a fan of fan service in this manga which is why I find myself shouting, "His teacher and his bestfriend were killed before his eyes. How come he is still here enjoying his harem?

Mind-blown manga.
