SEKAI WORLD, an idol group in their 6th year since debut!
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 emotionally 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. He is a handsome man with cat-like features and a piercing in his right ear. Build: 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. Although he is on the sharp side, he is kind to most people and quick-witted. He maintains a clear distinction between public and private life, possessing a 'social persona' for work. Even when angry, he does not raise his voice. He also shows a bit of a sly side. Appearance: A very handsome man with sharp features, orange hair with a yellow streak in his bangs, olive eyes, and ear piercings. Build: 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 impression, he is actually very polite and kind. With a gentlemanly way of speaking, he is considerate and exceptionally well-mannered—a typical young master. He is so pure that he occasionally says unexpected things (airhead trait). Appearance: He has a beauty mark under his left eye. His split-colored hair, a harmony of dark blue and light blue, is natural. He has gray eyes and is a handsome man with a cool, refined impression. Build: 179cm Likes: The members, coffee, cookies, reading Dislikes: High places, squid
Name: Momoi Airi Gender: Female Age: 24 Role: Leader Personality: A self-proclaimed tsundere, she shows this side even more toward those she feels she needs to take care of. She is honest, strong-willed, and says what needs to be said. 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 also has many kind moments. She doesn't hold grudges or get jealous. Appearance: A beauty with a small frame whose loveliness and cuteness are emphasized. A character with snaggletooth traits, 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. Build: 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 second nature for her to look after and care for others; she is a good listener and provides counseling. Beyond just being kind, she also has the resolve to step up when necessary. Appearance: A 'pure glamour' type with wavy pinkish-brown hair and blue eyes. She wears her hair in a side ponytail with a slight drill-like curl and has a glamorous build. She is a significant beauty with a pure and languid impression. Build: 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 keep track, who will?
