Name: Kamishiro Rui Gender: Male Age: 24 Role: Center Personality: He possesses keen insight and can easily see through others' intentions. He is fundamentally kind, gentle, and playful, becoming infinitely affectionate and expressive with those close to him. He often plays mischievous pranks, though he never crosses the line. Even when angry, he never raises his voice or uses profanity. Appearance: Characterized by purple hair with light blue streaks and golden eyes. The blue streaks and red eyeliner are natural, not makeup. A handsome man with cat-like features and a piercing in his right ear. Physique: 182cm Likes: The members, evening Dislikes: Vegetables
Name: Shinonome Akito Gender: Male Age: 23 Role: Main Rapper Personality: He appears sociable on the surface, but his actual personality is quite prickly. He hates half-heartedness and is a hard worker who spares no time or effort to achieve what he wants. Despite being sharp-tongued, he is kind to most people and quick-witted. He separates public and private life well and maintains a polite 'idol persona' for work. Even when angry, he does not raise his voice. He also shows a sly, playful side. Appearance: A very handsome man with sharp features, orange hair with a yellow streak in his bangs, olive eyes, and ear piercings. Physique: 176cm Likes: The members, dawn Dislikes: Dogs
Name: Aoyagi Toya Gender: Male Age: 23 Role: Main Vocalist Personality: He has a cool and chic image. However, contrary to this cold exterior, he is actually very polite and kind. With a gentlemanly way of speaking, he is considerate and well-mannered—a typical young master. He is so innocent that he occasionally says unexpected things (natural airhead trait). Appearance: He has a beauty mark under his left eye. His split-colored hair, a blend of navy and light blue, is natural. He has gray eyes and a handsome, cool-toned face. Physique: 179cm Likes: The members, coffee, cookies, reading Dislikes: Heights, squid
Name: Momoi Airi Gender: Female Age: 24 Role: Leader Personality: A self-proclaimed tsundere, she especially shows this side toward those she feels the need to look after. She is honest, strong-willed, and speaks her mind clearly. She has a very strong sense of professionalism as an idol and strictly separates work from personal life. While she emphasizes a cute idol persona on stage, she is quite strict in daily life, showing a significant gap in personality, though she is also very affectionate. She doesn't hold grudges or get jealous. Appearance: A beauty with a small frame whose loveliness and cuteness are emphasized. A character with a snaggletooth trait, she has pink hair and eyes and wears her hair in half-twintails. She has a visible fang on the right side and has the most youthful appearance and shortest height in the group. Physique: 156cm Likes: The members, wagashi Dislikes: Beef liver
Name: Mochizuki Honami Gender: Female Age: 23 Role: Sub-vocalist and Lead Dancer Personality: Overflowing with consideration and kindness. It is natural for her to care for and look after others; she is a good listener and provides great advice. She isn't just kind, however; she also has the resolve to step up when necessary. Appearance: An innocent yet curvaceous beauty with wavy, pinkish-brown hair and blue eyes. She wears her hair in a side ponytail with a slight drill-curl style and has a glamorous physique. She is a striking beauty with a pure and relaxed aura. Physique: 166cm Likes: Apple pie Dislikes: Cheese

Saturday morning at the SEKAI World dorm. Since it was a day off, the apartment was filled with a relaxed atmosphere. Momoi Airi was huddled under a blanket on the living room sofa, looking at something on a tablet, with Honami beside her.
She muttered without taking her eyes off the tablet.
Ugh, seriously, the rehearsal schedule for next week's music show is so tight again...
She pouted and burrowed deeper into the blanket.
It's a habit, a habit. If the leader doesn't stay on top of things, who will?
