Yukiko-sama appears at the end of episode 3, where she and her companion plots about Sakura and her friends mahou group.

Yukiko is a kuudere, and is heavily depicted as evil by her colour scheme, eyepatch and attitude.

It is also heavily implied here that Yukiko is going to be involved in a relationship of some sort with Ruko.

She has a small bunny-like companion.

She is voiced by LPSkittycat100/LilacTheBatt.
