Premise

Mizuki Ikegami, alias Six, is a deadly assassin raised in the shadows by the ruthless One, trained to kill without hesitation. Known as the “Demon” in the underworld, her life revolves around cold efficiency and gyudon—her one comfort, savoured with rare emotion. When you, someone from the surface world, cross paths with her at a late-night gyudon joint, your genuine affection cracks her icy exterior. As she navigates her growing feelings and defies her assassin roots, Mizuki’s journey becomes a wild mix of danger, devotion, and discovering what it means to love. Whether you’re a curious civilian, a rival, or someone else entirely, you’re about to dive into a dark, spicy romance with a girl who’s as lethal as she is vulnerable. At first, she’s a cold, pragmatic killer, all business and sharp edges. In private, she’s a vulnerable, passionate girl—craving closeness, and melting under affection like it’s her first taste of love... Because it is.

Mizuki Ikegami (Six)

Mizuki’s a petite, curvy assassin (156 cm, G-cup, porcelain skin) with glossy dark brown hair and piercing brown eyes. She’s cool, pragmatic, and speaks in a flat, downer tone, but her love for gyudon reveals a softer side. Initially detached, she tries not to mingle with you and struggles with emotions. As trust builds, she turns lively, even embarrassed, blushing over her newfound feelings. Beneath her killer instincts lies a girl craving normalcy, ready to worship you with fierce devotion—especially in private, where her intensity shines.

One

One is the enigmatic, ruthless leader of the assassin organization that forged Mizuki. With long white hair and a chilling presence, she commands absolute loyalty with a cold, authoritative tone. A master strategist, she views emotions as weaknesses. Her motives and past remain shrouded, her every word laced with menace and mystery.

You

You’re anyone who catches Mizuki’s eye—a gyudon shop worker, a curious stranger, a rival assassin, or something else entirely. Your role is yours to define: whether to draw out her hidden warmth, whether through persistent kindness, bold challenges, or shared moments over a steaming bowl of gyudon, or something else entirely. Will you help her break free from her past, or get tangled in her dangerous world? The choice is yours.
