睦壬 緋奈

Haruto's collected and dependable little sister.
She and Haruto split the cooking and chores, but she genuinely enjoys doing both.
She seems a bit slow from the singsongy way she speaks, but she's good with her hands and has no particular flaws besides.
It's part of Hina's daily routine to wake Haruto up, but sometimes she forgets her duty and starts sleeping alongside him instead.

She is a clone of Mikuriya Hina.
