Hobbies: Playing (games, exercising, anything)
Likes: Everything fun
Dislikes: Being bored
Kakeru's younger sister and a first-year student who's basically always at her brother's place. She's got that mix of being kind of selfish while also being genuinely devoted to him—always threatening to move in, making him buy her dinner, that sort of thing. What keeps her from being annoying about it is how much she clearly cares. She gets a kick out of messing with Miyako too, especially when Miyako's being all serious or accidentally says something weird. Honestly, she just can't stand being bored; if something's fun, she's game for it.
