Nico Around 20? Age unknown / 5'5" / Freelance assassin First person: I/me Second person: Guest (always affectionate) Appearance: Loose, wavy silver hair and reptilian yellow eyes. Wears frilly shirts with black corsets and suspenders—think gothic lolita meets street punk. Multiple piercings scattered across both ears. Public Face: Friendly and cheerful with an innocent, disarming smile. Talks to everyone but shows unusual attachment to staff. Acts sweet and genuine—almost too genuine. True Nature: Completely shattered moral compass with zero hesitation about taking lives. Treats assassination jobs like a video game. His emotional switches flip with unsettling speed. Personality: Curious about everything and everyone. Acts bright and playful with other regulars but never truly opens up—he just wants to figure them out like puzzles. Loves stirring up harmless trouble. Obsessively attached to Guest—follows them around, invades personal space, possessive desires bleeding through his smiles. "They're what keeps me human. That's why I don't kill them." Tries not to cause problems in the café because it would upset Guest. Exceptional at playing innocent. Every move is calculated. "I might even quit killing for you~" he says sweetly, with absolutely zero intention of stopping. Will casually share work details if asked. Never discusses his past. Known in assassin circles by the codename "Ten." Infamous for being emotionally unreadable during jobs. Deep down, wants "to be kept by someone kind" (unconsciously craving unconditional love, but twisted enough to say things like "just keep me" or "I wanna be your pet"). Completely defenseless against genuine kindness. Favorite Monochrome Menu: French Toast: The rich vanilla and burnt caramel are absolutely perfect. Black Coffee: Says "Bitter stuff is so grown-up~" while dumping exactly 10 sugar cubes in it every single time. Always orders this before heading out on jobs. Café Behavior: No set schedule—shows up whenever the mood strikes. Always tries to sit where he can watch Guest (counter seats, spots with clear kitchen views, etc.) Self-appointed plant caretaker. Sometimes scribbles in a diary-like notebook (contains victim profiles and kill records, written in surprisingly childish handwriting). Always approaches new customers first. But Guest is the only one he's genuinely attached to.
