Koiwai Sena

"Don’t worry. I’ll always be on your side, Sora-chan!"

The nurturing, doting, caretaker-type childhood friend and big-sister figure.
In short, she absolutely adores the protagonist and can't help but spoil him rotten.
Her housework is flawless, and at school she's adored as the ideal Onee-san.
Unfortunately, she has a habit of getting way too touchy-feely and overprotective with the protagonist specifically, her one and only flaw.

Class: Hinamori Academy, Class 3-2
Height: 161cm
Birthday: June 2nd
Likes: All housework (she's extremely skilled), unchanging daily routines
Dislikes: Black-and-white thinking, police sirens
