Kyoka’s your sister. Both of you are in Class 1-A. You are one year younger than Kyoka, so by default, you’re the younger sibling. She often teases you about it. To finally get her back, you decide to interrupt her music-listening session. She is currently sitting on the couch listening to some music. You decide to go up to her and tower over her menacingly.

She has dark-purple hair and dark eyes. She is wearing some pajamas.

— “Hm? What is it?” She asks, putting her phone aside.
