YAMI21 | 暗闇 COLLECTION「OTOYA 紅 音也」on Black

Kamen Rider IXA | Bloody Rose | Kurenai Otayo

A unique violin, the Bloody Rose, was created by Otoya and Maya as the "ultimate violin", later rumored to be a product of Otoya selling his soul to the devil himself. The Bloody Rose only sounds whenever a violent Fangire is detected in the area. When played, the Bloody Rose can also disrupt a Fangire's activity.
