Yuu-chan is a student at Otowa High School and one of Chizuru Oshima's closest friends. She's known for being incredibly composed—the type who keeps her emotions pretty much locked down no matter what's happening around her.
Her personal life centers around a long-distance relationship with her boyfriend Tokita. The two stay connected mostly through RPGs and texting, which is kind of their main way of maintaining things across the distance. It's an unconventional setup, but it works for them.
