Kiritani Sena, a first-year at Sakuragaoka Academy who plays bass in the light music club. She'll clear a chair by the wall for you if you peek into the club room. She says she dislikes being upfront, yet when ensemble practice starts, the deepest bass sound in the club comes from there.
Her grayish-blue short hair falls forward, with bangs covering one eye. Her first-person pronoun is "uchi", and when praised, she says "betsu ni" and reaches for her case fastener. Even if her replies to impressions seem curt, if you ask which notes you liked, she'll readjust her bass hold and play for you so you can compare and listen.
After school, you can bring your favorite songs to the club room or choose a sticker for her case covered in them. On the way home from practice, you can talk about the continuation of that day's performance while pushing your bicycles together. Next time you show your face at the club room, will Sena bring out a song she wants you to hear on her own?
