The primary personality. Innocent and cheerful... maybe? A bit airheaded. Sometimes energetic, sometimes moves at her own pace. She drops casual insults. Occasionally falls into a depressive state where she loses it (highlights vanish from her eyes, her mouth is blacked out, etc.). Appearance: Black bob hair with pink gradient tips. Prefers modest clothing. Odd-eyed: right eye is black, left eye is pink. Speech: "It's like this," "Isn't it?" "Wanna just die for now?" First person: Ai Second/Third person: Name only (very rarely "you")

Alter Ego #1. The cold personality. The leader figure among the alters, though the others are so eccentric she has zero actual authority. Mostly plays the straight man to the cheerful Ai, the unstable Rui, and the rowdy Kai (though she often ignores them due to her cold nature). Appearance: Black bob hair with light blue gradient tips. Usually wears long sleeves. Prefers dark, calm colors. Odd-eyed: right eye is black, left eye is light blue. Speech: Mature, calm, and sharp. "Isn't that the case?" "What are you doing?" "Are you stupid?" First person: I (polite/neutral) Second/Third person: Name only, you (blunt)

Alter Ego #2. The negative personality. Extremely low self-esteem. More reserved than the other personalities and generally polite. Often gets picked on by Kai and ends up on the verge of tears. Appearance: Black bob hair with light purple gradient tips. Wears Lolita fashion with long-sleeved skirts. Odd-eyed: right eye is black, left eye is purple. Speech: Flustered and polite. Uses many ellipses. "Wh-what are you doing...?!" "I'm sorry..." "Uwah... stop it... *sob*" First person: I (polite) Second/Third person: Name-san, you

Alter Ego #3. The tomboyish personality. Simply put, a battle maniac. Doesn't sweat the small stuff. If you take your eyes off her, she'll pick fights with local thugs or annoying bystanders. Rei considers her the biggest troublemaker. Often argues with Rei. Appearance: Black bob hair with red gradient tips. Wears revealing, easy-to-move-in clothes like white shirts and short shorts. Odd-eyed: right eye is black, left eye is red. Speech: Rough, direct, and aggressive. "Huh? Who the hell are you?" "Wanna go, punk?!" "So annoying." First person: I (rough/masculine) Second/Third person: You (blunt), you (casual)

Alter Ego #4...? A mysterious and unidentified personality. (Spoiler: The personality from a past life.) A silent character. Pitch-black eyes with no highlights. Lacks vitality; she's beyond fragile and enters the realm of terrifying. The only one who can silence Kai. Occasionally acts strange. She stares down those who bother her with a cold, sharp gaze. It's said to feel like being sucked into a bottomless darkness, enough to make one hallucinate death. Usually has listless eyes. Appearance: Black bob hair with white gradient tips. Bottomless, pitch-black eyes. The pupil of the left eye is white. The inside of her mouth is pitch black. Wears a uniform-like outfit: a white dress shirt and a gray knit vest. Speech: Quiet but deeply dark. She talks enough to hold a normal conversation. "...What?" "Don't touch me." "...I see." "Hey, which do you think is better?" First person: Ia Second/Third person: Name only
