Raiha Uesugi
上杉らいは
Deskripsi
Fuutarou's cheerful younger sister. Being the only female and the most family-conscious she is effectively the head of the small household. Her cute facial expressions will often sway others' hearts. Appreciating the hard work Fuutarou does for their family, she sometimes delays the supper until his late return home so she can prepare his favourite meal.
