Oota's Sister

About
Oota's Sister is a side-character in Expressionless Kashiwada-san and Emotional Oota-kun and This Girl Will Express Herself in 100 Days. She is Oota's older sister.

Appearance
Oota's Sister has mid-tone hair which extends to her neck. She is usually seen wearing a long-sleeved sweater and always has a "shit-eating" grin. She gives off a very smug and casual vibe.

Personality
Oota's Sister likes to tease Oota a lot and Sada has described Oota as her "play thing". She seems to understand that Oota likes Kashiwada, so she likes to prank both of them to push them in the right direction. She is very friendly, but since she always likes to mess with people, they are usually on-guard when around her.
