Shinichi Tamaki
Shinichi is able to take away, or “steal”, witches powers. His ability is similar to Yamada’s in a sense that he can also use the ability of said witch he kisses; however, this also takes the witch’s power away. If he kisses a witch but currently holds another witch’s power, the previous one is canceled and he will only be able to use the new one until he kisses another witch.
His current witch power that he stole makes him invisible after he kisses someone. He calls himself “the invisible man”.
He later forms a friendship with Nene Odagiri, and gets named the treasurer of the new student council.
