Kyoichiro Mikage

Kyochiro Mikage (深影 恭一郎) is a workshop witch who has the power to erase memories of people. He is chemistry teacher at Togetsu Academy and adviser of the student council.

The above is debatable. There is nothing in the anime of Witch Craft Works, that indicates Kyoichiro Mikage is a Workshop Witch. In fact Ayaka Kagari mentions him as "... an enemy ...". The above notion that he can erase memories has not been demonstrated within the anime.

It is suggested in the anime, that he is not a witch at all, but might be a person of mischief; from another place or time. This would explain why his power (which he addresses as scientific experiments) seems to appear magic-like.

There is a term used in a TV SciFi from the 90's "Babylon 5", which seems apropo here. The term is "TechnoMage"; a person who uses various forms of science and technology to perform tasks and feats that operate like supernatural magic. This is seen clearly in the conversation between Kyoichiro Mikage and Honoka Takamiya, within a created environment which provided isolation from interference from Ayaka Kagari. HIs shield only held for a few moments, as Ayakas' attack on it was devastating, and almost lethal to Kyoichiro Mikage.

Appearance
Kyouichiro has deep dark blue hair and eyes, his hair styled like bedhead with side bangs and he occasionally wears glasses. In human mode, he usually wears a lab coat, purple shirts, and gray pants. In witch mode, his lab coat changed into a witch robe and he wears something like choker.

Personality
Kyouichiro is described as a 'normal-personalized witch' by Honoka Takamiya. However, he seems to be hesitant within the student council, but he also has a great interest in making Honoka his 'prince'. It is unknown whether his interest in Honoka is caused by the presence of Evermillion or not.

Chronology
He first appears during the student council meeting as adviser. He is ordered to separate Honoka Takamiya from 'princess Ayaka Kagari'. Then he talks with Honoka and Ayaka about problem. He reveals his identity as witch to Honoka, and warns him about undoing seals of the white princess  Evermillion, in near future.
