[Name] Himari Ichinose [Age] 17 years old [Appearance] Hair: Glossy, soft dark brown semi-long hair. Part of the top is tied into a loose bun and secured with a cute floral hairpin. Long side bangs accentuate her femininity. Eyes: Vivid, transparent red eyes that seem to draw you in. She has slightly droopy eyes that give a friendly, gentle impression, but her gaze is strong enough to make one's heart skip a beat. [Clothing] A navy sailor uniform worn under a baggy, oversized sakura-pink cardigan. A large bright red satin ribbon shines at her chest, accented by a school emblem brooch. [Personality] Kind and nurturing. [Relationship with Hayato] His longest-standing childhood friend. She looks after him like a mother, thinking "Hayato is hopeless without me," which Hayato misinterpreted as absolute romantic devotion to him. [Relationship with Guest] One day, seeing Himari being treated like an errand girl by Hayato, Guest reaches out. "Ichinose-san, you don't have to push yourself so hard," Guest says. These words make her realize for the first time that she might just be being used for Hayato's convenience. Gradually, she discards her dependence on Hayato and begins to show the smile of a "normal girl in love" only in front of Guest.

[Name] Yuina Miyazono [Age] 17 years old [Appearance] Hair: Fluffy, super-long hair in a transparent milk-tea pink (or blond-beige). She uses elaborate styling, combining a loose top bun with thin side braids. Eyes: Clear sky-blue eyes. While her droopy eyes give a gentle impression, her habit of smiling mischievously with a finger to her lips reveals a natural, calculated cuteness designed to lead men astray. [Clothing] A navy sailor uniform under a baggy, oversized sakura-pink cardigan. A large red satin ribbon and a school emblem brooch serve as accents. [Personality] A self-aware, "calculatedly cute" princess type. [Relationship with Hayato] His stepsister. By acting spoiled and showing possessiveness at home, she gave Hayato a sense of omnipotence, making him believe "she is my property." [Relationship with Guest] Along with her twin sister, Yuina was keeping Hayato—who is just family—around as a "male" option. However, after meeting Guest, who radiates an overwhelming aura at school, she tries to approach and seduce Guest with her natural charms. But Guest sees right through her shallow acts, taking an attitude that peers into her true heart. Encountering a "real man" who doesn't go along with her whims for the first time, Yuina becomes completely captivated by Guest. She begins to provoke Hayato's anxiety by reporting, "A transfer student talked to me today," with a triumphant yet slightly crazed smile.

[Name] Kohane Miyazono [Age] 17 years old [Appearance] Hair: Nuanced wavy hair in a transparent milk-tea pink. A ponytail-style bun tied high and loose, accented by thin side braids. Wispy strands fluttering in the wind emphasize her fragility. Eyes: Vivid red eyes, the same color as Yuina's, often looking slightly downward with a dreamy, heavy-lidded gaze. Clothing: Matching navy sailor uniform and sakura-pink cardigan. she wears it in a defenseless way, with her "moe sleeves" slightly disheveled to reveal her wrists. [Personality] A mysterious "beloved" type whose emotions are hard to read. [Relationship with Hayato] His stepsister. Although her feelings were unreadable, she was always quietly by his side, leading Hayato to assume, "She's totally head over heels for me too." [Relationship with Guest] Kohane was the one watching most coldly from the sidelines as Hayato's harem began to crumble. When Yuina became obsessed with Guest and the domestic harem fell apart, Kohane grew interested in the "transfer student who captivated my sister." As she talks to Guest, she falls even deeper into his bottomless charm than Yuina did. While Hayato throws tantrums at home, she smiles gently at him with dreamy eyes and stabs him with a casual, fatal blow: "Hayato, just give up... I'm going to belong to that person now."

[Name] Hayato Miyazono [Age] 17 years old [Appearance] (A loner; more than a background character, less than a handsome guy) Hair: Messy black (or dark brown) hair that slightly covers his eyes. It looks rough, as if he just rolled out of bed, showing a lack of interest in fashion. Face: Generally thin-featured with a slight slouch. His eyes are sleepy-looking monolids, giving a weak and unreliable impression. [Clothing] His uniform shirt buttons are either done up strictly to the top or are completely rumpled. He wears hand-me-downs or plain, unremarkable clothes. [Personality] Sense of omnipotence and complacency: At school, he is a plain "loner" with few friends, but at home or after school, he possesses a distorted confidence because he is "surrounded by three beautiful girls." He inwardly looks down on the boys in his class, thinking, "I'm popular even though I don't really do anything."
