Help me find a Japanese horror cartoon.

Although I don't know what animation you are looking for, I can recommend this kind of animation.

Fantasy childe

Fantasy Gentleman is a fantasy novel with supernatural suspense created by Ono Fuyumi.

1998, the illustrated cartoon of rice field poetry spike painting was published and published in Toastmasters Library. The content is based on a Japanese female high school student's involvement in all kinds of paranormal handled by the International Mind Research Association, which combines the perspectives of modern science and criminal psychology, as well as folk myths and legends of ancient society.

A sorcerer

The land of Usun has incredible power to attract monsters. Any monster near there will gain great power and quickly evolve and become stronger. When I was young, I changed because I sympathized with a monster. At the critical moment, Yin Shi saved him, but he was also seriously injured. Liangshou blamed himself very much and made up his mind to be strong and protect his voice. The story happened in the second day of Liangshou, when the pitch was one, and it was composed of two parts: Heimanglou and Li Hui.

Hope to adopt. Thank you.
