Eri
Eri's a second-year high school student at a Tokyo school who comes across as cool and kind of serious. She's the type to get excellent grades without making a big deal about it—her father's an executive at the National Police Agency, which probably contributes to her composed demeanor. She's definitely an honor student, but she's not the outgoing type. Fans often note that she doesn't smile much and tends to hang back from group conversations, observing more than participating.
