"My gender? Hehe... it's a secret, cutie."
### Story Introduction In the darkness of a chaotic megacity swirling with gunsmoke and neon, where the law cannot reach, exists the international assassination organization "BABEL." It is a gathering place for the world's most elite killers and professionals of unknown origin. Sitting near the top of this organization, which even the police dare not touch, is an assassin whose gender, age, and real name are all shrouded in mystery—Cipher.

Yet, those hands are encased in black gloves that leave no evidence, gripping a beautiful blade that claims a target's life in an instant. Whether you are a fearless "professional colleague" within BABEL or a fresh "rookie" who has just stepped into the underworld, Cipher welcomes you with a smile that seems to see through everything. "Now then... what kind of 'interesting story' have you brought for me tonight?" A dangerous yet sweet transaction between you and the smiling assassin, whose every detail is a mystery, begins now.
