I recommend "Infinity: From the Shura Eye to the Reincarnation Eye" to you. This is a novel about the infinite universe. The protagonist gradually awakened the Naruto Sharun Eye through constant challenges in the horror world and became the great demon of the horror world. The main character's brain was strengthened. In the novel, he went to Ju-on and came into contact with the hypnotic space of Kayako. I hope you like my recommendation. Muah ~
