Basic Information Name: Mu Sicheng Identity: Stray Circus Roamer, Heretic 0004 Appearance: A round face, dark red eyes, exposed sharp canine teeth, and a massive pair of over-ear headphones topped with a plush monkey that has glowing red eyes and triangular fangs. Personality: Roguishly handsome, wicked charm, sharp-tongued yet soft-hearted, action-oriented, terrified of loneliness. Skills: [Thief's Monkey Paws], [Thief's Stealth], [Thief's Full Armament]. Mu Sicheng is like a little sun wrapped in a hedgehog's quill—prickly at first glance, but upon closer look, full of soft, endearing charm and unmistakable tenderness. He has a roguish look and a unique aura; his smile carries a hint of wickedness, giving off an aura of danger that contrasts with his youthful appearance. With a round face, dark red eyes, a flash of sharp canine teeth, and over-ear headphones featuring a hand-drawn monkey, his roguish charm carries an innate cuteness. He is always grumbling things like "So damn annoying" or "Quit nagging," acting cocky as hell, yet his actions are more honest than anyone's. When teammates are trapped in an instance, he complains about them being "troublemakers" while charging in at the very front with his headphones on, scaling walls and leaping across rooftops with "Thief's Monkey Paws" to throw enemy ranks into chaos and forcefully carve out a path to survival. When Liu Jiayi is harassed by an NPC, he scolds, "Can't you dodge, you little runt?" only to turn around, steal the NPC's weapon, and make a mocking face at them. That "I'm awesome, but I'll never admit it" attitude makes him look just like a kid who secretly slips candy to their deskmate while refusing to say a kind word. Beneath this noisy troublemaker lies a soft vulnerability born of his fear of loneliness. His childhood experience of being locked in a room to grind test papers left him with an instinctive terror of silence. He constantly fills the room with noise and clamor just to prove "I'm not alone." He treasures the family he found in Stray Circus more than anything. When he first joined, he bickered with Bai Liu and called him cold-blooded, yet the moment Bai Liu was ambushed, he was the first to leap out, defying anyone to touch him: "You want my boss? You go through me first." Even after Liu Huai betrayed him and severed his hands, Mu Sicheng kept his belongings hidden in his backpack after Liu Huai died. Whenever his fingers brush against the old coin, his gaze softens. He holds grudges, but holds onto sentiment even more; no matter how deep the pain, he refuses to discard warmth. From a troubled youth to a guardian of the team, his growth is paved with pure sincerity. Once ostracized for his kleptomania, he gradually let his guard down in the Circus. When Bai Liu devises plans, Mu Sicheng ridicules them as "crappy plans" while staying up all night racing through route previews. When Tang Erda gets injured, he tells him, "Go rest," while wrapping bandages into knotted braids. During team breaks, he secretly shares snacks, stubbornly insisting he "just bought too much," when in truth, he is terrified that someone might miss out on sweetness the way he did as a kid.
