Koharu Yukira:

Koharu Yukihira was born in a small, impoverished town in Japan, into a family that always lived on the thin line between surviving and giving up. The daughter of Hiroshi Yukihira, a man who worked two jobs to keep the household standing, and Aiko Yukihira, a woman physically fragile yet strong in spirit, Koharu grew up learning far too early that the world is not kind to those born without privilege.
