Yui Kashī

**Yui Kashī** (香椎結衣 *Kashii Yui*) is the classmate of Junichi Hashiba.

## Appearance

Yui's an attractive girl with waist-length or hip-length black hair, blood-red eyes and she has what appears to be a snake beret in her hair.

When dressing up as **Mistress BoA**, Yui has long blonde hair (red hair in the anime) that's tied up into twin-tails, blue eyes, and then the snake beret becomes a necklace to dissociate herself from her real-life counterpart.

In the anime, Junichi Hashiba's friends mention that Yui's the only girl, cause she doesn't have big breasts like the other girls.

## Personality

Yui puts on a public façade of being a nice and friendly girl who is excellent at academics. She is referred as the school's Madonna (an idealized virtuous and beautiful woman) by Junichi Hashiba's friends as she is smart and beautiful. She is trusted by almost everyone who is not aware of her true personality and this has given her certain privileges which she takes advantage off.

In the anime, we get to see Yui's inner psyche, which it shows her to be a highly narcissistic, manipulative and unstable individual who believes the world revolves around her. She genuinely believes herself to be a queen with her friends being numbered and Junichi Hashiba being her favorite lapdog, whom she has known ever since middle school.

She vindictiveness and emotional instability becomes evident when she becomes very angry when she doesn't get her way. This happened when she asked Junichi to go on a date, and respectfully declines. Her favorite song is TELL YA! by Sik K. The only thing stopping her from hurting Junichi was Ranko Honjou intervening and threatening to expose Yui as **Mistress BoA**.

Yui secretly dresses up as a twin-tailed, red-haired (blonde hair in the manga) idol named **Mistress BoA** who live streams under the alias in a way to vent her struggles and frustrations without consequence as well as collects financial donations from her followers online.

## **Relationships**

### Junichi Hashiba

Junichi and Yui have been friends since middle school, and she really likes him. She's wanting to be good enough to want to date him. Though Yui's obsessed with Junichi and she wants him to be her lapdog and servant.

### Ranko Honjou

Ranko is Yui's friend and rival. Initially, Yui had rough encounters with Ranko viewing her as an enemy, but when Ranko helped Yui sort out her feelings for Junichi, they started being more friendly with each other. Ranko would sometimes stream as a guest alongside with Yui as **Mistress BoA**, she also got to kiss Yui while under the influence of some poisonous mushrooms, making her all flustered and developing some feelings for her.
