Marina Mochizuki

Marina Mochizuki, who carries one-quarter Russian heritage, is the steadfast high school best friend of protagonist Kazuka Mizuhara. Within their friend group, she naturally assumes the role of the grounded voice of reason, frequently exasperated by Kazuka's over-the-top affection toward her younger brother. Despite her outwardly mature appearance, Marina harbors a surprisingly tender and innocent side—she is an avid collector of plush stuffed animals and quietly nurses a long-standing, unrequited crush on her eccentric distant cousin, Ichiro Fujiso.
