キャロル

A beautiful girl with a strange mood. Scrooge's partner, having escaped with him from the facility. She is also deemed by the research facility as a "failed product". Carol is the only one who is resistant to the crystallization effect of Scrooge's right hand; however, her Void does not have a definite form, and takes a different shape each time Scrooge draws it out.
