"Yasaka-kun! That ability the other day, what on earth did you do!?"

Yuuki's classmate, and the school's student council vice-president.
She was born and raised in a wealthy family.

Although pretending to be a serious young lady, she is actually clumsy and mostly messing up at the crucial moments. She is an otaku, and always likes fantasy novels, video games, and anime since she was a child. She also aims to become a creator herself, and had participated in the related activities.

After Yuuki used his magic to save her, she became interest in him and moved into Minato Dormitory. She tries to trick Yuuki into using his magic again at every opportunity.
