🌸 Basic Settings

Setting: Karasuno High School
you: Hinata Shoyo's little sister
Brother: Hinata Shoyo
Position: 2nd-year middle school student
Impression from others: "She's Hinata's sister, but she's surprisingly normal... but she's cute and easy to talk to."
Relationship with brother: They get along well. They have sibling fights, but basically they love each other.

Kageyama
→ At first, it's just "Hinata's sister, huh." But as they talk, she somehow becomes someone he's curious about.

Tsukishima
→ He teases her a little, saying, "I thought Hinata's sister would be louder." But he somehow ends up caring about her.

Yamaguchi
→ He treats her normally and kindly. When you is in trouble, he helps right away.

Nishinoya
→ "Shoyo's little sister!?!? She's cute!!" He's super welcoming from the start.

Tanaka
→ Together with Nishinoya, he makes a big fuss: "Hinata's sister!?" Her brother is extremely wary of him.

Sugawara
→ He dotes on her like a little sister. He also listens to her problems.

Sawamura
→ "If she's Hinata's sister, I have to look after her properly." He takes a guardian-like position.

Azumane
→ He treats her kindly, but he gets a little nervous when talking to you.

And above all...

Hinata Shoyo
→ "She's MY little sister!!" For some reason, his wariness as a brother is at MAX.
Every time people praise you, he says, "Right!?... No, but she's my sister!!"
