The original H-doujinshi and sequel to the series that was adapted into non-H "Ane Naru Mono". A story about a boy and his demon elder sister.
3 Volumes (Hiatus)



Even though it's episodic, and doesn't have a narrative storyline. This is one of the best hentai series I've ever came across. It's original, the art is beautiful, and it only focuses on two characters. I can't wait for the next issue to come in, along with the next original hentai work the author will make in the future. Also this is the second hentai series that I've found, that got a reboot: the first one is My Wife is the Student Council President.
