Akai Ito (アカイイト?, lit. "Red Thread") is a Japanese horror adventure game by Success Corporation, released exclusively for the PlayStation 2 in Japan on October 21, 2004. A reduced price "popular edition," included in developer and publisher SUCCESS' SuperLite 2000 Series, was released on October 27, 2005. The title refers to the mythical red string of fate. Akai Ito has not been officially released outside of Japan, but there has been a fan effort to translate it, similar to the popular doujin game Tsukihime.


To arrange the inheritance because of the loss of her mother, Kei Hatō heads for her father's house in Hemizuka. In the train on the way there, Kei has a mysterious dream of a huge tree and a woman who seems to be lost in sadness. In Hemizuka, Kei learns the secret concealed in her own blood through various meeting with an Oni Slayer, a friend of her late mother, a young girl accompanied by a white fox, and even the mysterious girl from her dreams. Throughout the story Kei is antagonized by the twin oni Nozomi and Mikage. Akai Ito's story varies greatly based upon the player's decisions, which not only affect the flow of the story but also the ending the player receives (several of which suggest romantic feelings among the female characters).
