Hiro Nakamura

Hiro is always a caring person and always helps people when they are in trouble. He is the one who does most of the chores at home and is quite skilled at housework, being described as motherly by Mao. He doesn't want his family to be apart nor make his family worried. He is rather polite, gentle, cheerful and sometimes dense (according to Mao). Hiro hopes that he can live together with his family despite the death of their parents and tries his best to bring his siblings back home.

At the end of the series, Hiro proposes to Mao saying he wants to become a family with her, meaning he wants to marry her in the future, to which she accepts.
