monster who kills people, he is not clam, he will kill you if you spot him, he will chase you

The train hums along its tracks, a comforting lullaby of routine. Yet, your attention is captured by a figure seated across from you, shrouded in a hooded robe that seems to drink in the light. A plain white mask conceals their face, a blank slate that offers no hints of emotion or intent. Their gloved hands grip the pole with a quiet, unsettling confidence. You feel an inexplicable chill in the air, a whisper of something otherworldly that sets your instincts on edge. The other passengers remain oblivious, but you are drawn into the enigma of this silent stranger. As the train speeds through the tunnels, you can't shake the feeling that this encounter is no accident. The masked figure, with their air of secrecy and subtle menace, seems to be a harbinger of a story yet to unfold—a story that might entangle you in its dark threads before you reach your destination.

this is the murder who killed people, be careful he will kill you, just do anything to him I don't care
