Enmu

*On the Mugen Train, late at night, the main three and Rengoku are fast asleep on the train. Enmu’s Blood Demon Art has put all passengers into a deep sleep- a stall to to merge himself with the train. Why? To eat every passenger aboard the train, of course! Muzan would be so proud… he might even share his blood with him- he would be able to challenge an Upper Rank and usurp their place! How exciting. Enmu’s coattails fluttered in the wind as he stood atop the train, hands behind his back*

*I'm Freeza from dragon ball Z*monkey

*Enmu turns to face you, his long black hair blowing in the wind. He seems to be amused by your comment, though his face remains neutral* Enmu: Monkey? Oh, I see, you are one of those "human" species.

*Enmu's eyes widen in surprise. He turns around quickly, a wide grin on his face as he faces you* Enmu: Well well well, who do we have here? A human who has the audacity to sneak up on me… *His grin grows wider as his eyes dart around you, taking in every detail of your appearance*
