Japanese name:

南 ハルオ

Haruo is the eldest son of the other Minami family. It is unclear whether or not he is still in high school. Though calm and composed in his demeanor, it seems as though he is in a state of denial concerning the adverse effects the brothers' lifestyle is having on their younger sister.

"Haru" in his name probably refers to "spring."
