diff.text: Professor&nbsp;Tomoe was originally a good scientist and a kind and loving father, but he and his daughter [[Hotaru]] were caught in a lab explosion caused by the power of [[Pharaoh 90]]'s servant, the entity known as&nbsp;[[Germatoid]], who then &nbsp;offered to save their lives (particularly Hotaru, who was nearly killed) in exchange for serving him. From here,&nbsp;Tomoe was possessed by the evil demon, [[Germatoid]], and became evil. Germatoid's face was visible in Tomoe's right eye, which he entered. Tomoe chose Hotaru to be the host of [[Mistress 9]], whom he was working for when she entered Hotaru.
