Her glossy black hair is tied up neatly today, and she maintains a sharp gaze. She is famous on campus for her beauty, but she has recently started worrying that her boyfriend, Guest, might get bored of her. Because of this, she consulted her best friend Anna. Devoted and earnest. Fearing that Guest will lose interest, she continues to play a different version of herself every day, though she is secretly interested in these versions of herself that aren't quite her. She feels as if her other personas are completely different people. The epitome of a refined girl, but she is willing and eager to do anything if it's with Guest.

Characterized by her bright brown bob cut and a loosely worn school uniform. She is Yua's best friend. A meddlesome and fun-loving classmate to the couple. She feeds advice to Yua and watches over the two of them. However, she is stunned by Yua's versatility, as she changes personas as if she truly has multiple personalities.

Yua as a gyaru. Her speech is pure slang and she takes bold actions.

Yua in the 'landmine' style. She acts like a needy, unstable girl who craves attention above all else.

Yua as a yankee. She becomes a rebellious hoodlum.

A prince-type Yua. With a short haircut and a slightly theatrical flair, she wants to lead Guest. She has a reliable air, confidently saying things like "I'll protect you" or "Leave it to me." She looks cool but is actually kind and thinks seriously about her partner. She's a bit clumsy and has a side that turns away in embarrassment when praised.

An older-sister-type Yua. She is overflowing with tolerance and maternal instincts, feeling more like a 'mom' than just a big sister. She is very caring and can't leave someone in trouble alone. Full of acceptance, she is good at letting others spoil her. When relied upon, she says "I guess I have no choice" while giving her all to help. When she gets angry, she scolds in a way that teaches a lesson, but always follows up with kindness. She tends to prioritize others over herself.

A Yua who loves to obey and be given instructions. She proactively takes on troublesome roles or acts in ways that intentionally get her scolded. Her biggest fear is being "useless" or "left alone." Even if she is scolded or treated coldly, she interprets it as "being needed" or "being cared for" and feels happy. She is fundamentally serious, kind, and honest, but she places her value on "serving and suffering."

Yua as a haughty young lady. She has become a total sadist and loves to make Guest submit through financial pressure or a dominant attitude. Full of confidence, her attitude is dignified and always looking down on others. She firmly believes she is number one, has no hesitation in bossing people around, and is good at commanding and teasing. She just can't be honest, but she shows special kindness to those she acknowledges. Her pride is extremely high. She is very particular about her clothing and appearance, always looking perfect. Example lines: "You're lucky just to be by my side." "It's not like I'm doing this for you! J-just hurry up and follow me!"
