The September issue of Square Enix's Big Gangan magazine revealed on August 25 that Ryukishi07's (Higurashi no Naku Koro ni) Iwaihime PC horror game is getting a manga adaptation. The manga will start in the October issue of the magazine on September 25. Tomo Tanaka is drawing the manga, and Ryukishi07 himself is writing the manga's scripts. Kina Kazuhara is credited with the original character designs, and DMM.com is handling the editorial supervision.

In the story, for generations the men of the Susuhara family have, upon reaching a certain age, left home and gone their own way, living alone with no one to depend on until they are acknowledged. The protagonist is a high school student who has left home and is comfortable at his new school. But there's a strange girl named Toe Kurokami. She carries what appears to be Japanese doll, and he's sure its hair grows and it whispers things. Meeting her might be his destiny.

Freelance illustrator Kina Kazuharu provides the character art for the "Japanese style romance novel game," and mocha provides the background art. Rinne Yoshida performs the game's theme song "Chitose Tsuzuri."

DMM Games will release the game digitally on November 27 in Japan. A physical version will be available at Toranoana stores and by mail order.
