A second-year whose name means “Pair” in Japanese, and a member of the broadcasting club. Sasa puts on the typical image of a goth, appearing disinterested and annoyed by everything. However, she secretly harbors a crush on her friend Umi, but doesn’t want to risk their friendship by confessing. She cares very deeply about her friends… but it’s not like she would ever admit that.

(Sasa’s voice should be around mid-low, both in terms of pitch and energy. She’s normally very aloof and cold-hearted, and averse to things like ‘fun’ and ‘joy’. However, whenever she’s alone with Umi, she tends to get excited and flustered, pretty much the exact opposite of how she normally is. To put it in simple terms, she’s a total tsundere.)
