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 ...". 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.
