Lamia is a demon doctor who is very small. Her name is possibly an allusion to the mythological demon. Later in the series, she seeks Furuichi's help to find Lord En on Hilda's request. Furuichi suspects her of being a tsundere character. Lamia carries a pistol loaded with bullets containing demonic concoctions that can erase memories, force a person to do one's bidding or, in the case of Oga, trap him in a psychic loop. She is always accompanied by two small muumuu pets, one of which sits atop her head and often mimics her mood. Her age is unspecified, but her appearance is that of a pre-teen girl. Her mother is general Laymia of the 34th Pillar Squad.
