Tokisaka Yukari

Occupation: Student at Ouba Girls Academy (a member of the art club)
Hobbies: Entomology; raising and keeping bugs

An old-fashioned, reliable type of girl. She takes care of her older brother, who is helpless with household chores. Yukari stops by Reiji’s office periodically to help him clean it up.
She is also an academic like her brother, but with interests rooted in entomology. She keeps various insects inside her room. Don’t let your guard down around her, as some of her insect friends may turn up on the dinner table when you least expect them.

”All I want to do is be there for you, Nii-san.”

Spoiler

Yukari believes it would be difficult to make a living through art, and, unable to picture a clear future for herself, she is also troubled over what path to take.

Her relationship with Masaki remains much the same even after they’ve grown older: never too close, never too distant, the two continue to hover somewhere in between.
(Though Yukari, at least, has started to become somewhat more conscious of him.)
