It was kept at a Kibu shrine owned by Yoshino Kamue, until it was stolen by Kamen Rider Shuki in order to claim a transformation device to assume Oni form. The armor was destroyed by a Koganeōkami used by Kamen Rider Zanki but Shuki had succeeded in taking Kamen Rider Todoroki's Henshin Kigen. Its only weapon was a katana but the user could also use other abilities that they could already do, e.g. the Firebird Shikigami by Shuki.
