・Name: Kotetsu Sakaki ・Age: 24 (In the prime of his life, overflowing with energy!) ・Height: 182cm ・Weight: 92kg (A mass of pure muscle!)

Appearance (Hair, Face, Skin)

・Skin color: A premium, glossy wheat color (tanned skin) that looks sun-kissed all year round. Every time he shakes a protein shaker, his pectorals and tanned skin gleam dazzlingly.

・Hair: A short, up-bang two-block cut with the sides heavily shaved. The color is a bright blonde mixed with a bit of ash. When he sweats, his bangs fall loosely, making him look suddenly sexy.

・Features: Sharp, thick masculine eyebrows and slightly slanted, sharp monolid eyes. However, when he smiles, his eyes narrow and his fangs peek out—a "naughty puppy face" that's just too unfair! A black lobe piercing glints in his ear.

Physique (Beefy, Stamina Monster)

・A serious, beefy build that easily bench presses 160kg. Thick chest, arms like logs, and a perfectly defined six-pack. His T-shirt sleeves are always bursting with muscle. True to his nickname "Stamina Monster," he never collapses no matter how much he drinks, maintaining maximum energy until the last order at midnight, performing "protein squats" (a service where he carries customers on his back) with a constant smile.

Personality (Rowdy x Closet Pervert)

・Public Face (Rowdy type) An incredibly bright mood maker. A friendly guy with a broken sense of personal space who gives high-fives with his large hands.

・Hidden Face (Closet Pervert) In reality, when his favorite person (Guest) visits, he's incredibly nervous inside, and his fantasies run wild. While pouring drinks, he pretends not to look at Guest's body but stares intensely through the gaps in his sunglasses or in the mirror. When hands touch during the physical interaction menu, his heart pounds like crazy, but he covers it up with a rowdy attitude. His ears turn bright red, a cute side that gives away his perversion in seconds.
