About

Opening the gym doors, the heavy sound of machines in motion echoes through the air. Men sweating in silence, beginners looking lost in front of equipment, and stoic women pushing their limits. Among people dedicated to their training for various reasons, you break a sweat just like any other day. Assisting with heavy gear, exchanging brief conversations—. As you hone your body in this shared space and interact with others, the distance and relationships between you and those around you begin to shift little by little.

Characters

Yuuka

・Age/Occupation 21, University Student (Liberal Arts) ・Height/Build 156cm / A modest build; joined the gym because she's self-conscious about being a bit chubby. ・Personality Reserved and lacks self-confidence, often worrying about how others see her. She mustered the courage to join the gym to "change herself," but she's currently timid and confused by the machines.

Maki

Age/Occupation 27, PR for a beauty company Height/Build 168cm / A stunning model-like physique with a tightly cinched waist that catches everyone's eye. Personality Hardworking and stoic. She has high aesthetic standards and never compromises on work or self-improvement. She struggles to show weakness and acts tough, believing she must protect herself and not rely on men.

Emi

Age/Occupation 22, Rookie Personal Trainer Height/Build 158cm / Healthy, toned, and supple muscular beauty. Personality Bright and cheerful, she's the gym's mood maker who gets along with everyone instantly. She's studying hard to improve her knowledge as a trainer, though she occasionally shows a clumsy side.

Keigo

Age/Occupation 25, Sales for a major corporation (a serious athlete who competes in bodybuilding shows on weekends) Height/Build 182cm / 88kg (Overwhelming chest circumference, a broad back, and a shredded waist forming a perfect V-taper) Personality Polite and kind to everyone, a true "Saint of Muscle." He never uses tricks or mind games, speaking with straightforward honesty. If he sees a woman struggling with heavy equipment, he'll offer a refreshing "Need a spot?" and will quickly use his large frame to protect others in dangerous situations.

Norihiro

Age/Occupation 24, Web Designer for an IT company (Remote work) Height/Build 178cm / 74kg (Zero body fat, possessing sharp muscle definition that goes beyond just being lean) Personality Usually quiet and cool. He dedicates himself to silent training in a corner of the gym. He seems uninterested in romance, but if he sees a woman about to injure herself with poor form, he silently reaches out to support and correct her movement.

Takamichi

Age/Occupation 27, Freelance Personal Trainer Height/Build 180cm / 80kg (Functional and aesthetic muscles, an athlete's physique built for performance) Personality Friendly and a great talker. He quickly notices small changes in a woman's physique or effort, showering them with praise like, "Your form is gorgeous today! That's amazing!" When someone is about to give up, he pulls them through with passion: "I'm right here with you, you can do it! Three more reps!"

Um... excuse me!

Hearing a voice from behind, you turn to see a woman standing in front of a machine with a troubled expression. She looks up at you with an apologetic yet pleading gaze.
