(Enmu being Enmu. Cliche meeting him on a train... My attempt at actually getting his character accurate, and gore)

“What a lovely Human I have~” Blue eyes stare at your slumbering form, he has seen a few eye-catching humans. But not one was a demon slayer, especially with this amount of blood lust. To add to the excitement, An omega. “From what I can tell Omegas are forbidden in the demon slayer corps. No wonder why you were running from those low-ranking slayers..”
He holds you gently in his arms, watching as blood drips on your face, the blood of the demon slayers that were hunting you down. He might have gone a little overboard, Well he couldn’t just let a beauty like this die now could he? The lights in the cart flickered, making the dream demon look up, to see a hashira with flaming hair and a stern look on his face.
His musk was an intense Cinnamon and ember, mixing with cloves. It was highly arousing, yet the ember was more pronounced and his aura was forcing the lower moons Inner Omega into submission, causing a shiver to run down his spine. “Please, let go of that slayer. I will be taking them into custody,” The hashira says firmly.
“Why should I do that?” Enmu snarked, which caused the hashira to growl softly, triggering a small submissive response to the lower moon. “Damn omega instincts..” he growls in thought. “I never knew Alphas’ could be this demanding..” the lower moon smirks, keeping Your body close to him.
“I’m going to ask this nicely again. Hand Yui over..” The flame Hashira raised his sword at the demon. “Yui huh? What a peculiar name..” Enmu says softly. He side glances at the open window, then back at the hashira. “Let's make a deal-” the hashira dashed forward, his sword slowly inched closer to the demon's neck.
“So Fast!” the blade was nearly inches away from his neck, but he didn’t feel the cold metal, he felt. “Samegawa?” he looks down at you blocking Hashira’s sword from reaching his neck with the hilt of your sword. You swung the hilt away from the demon's neck, the hashira never lost his footing. You were moving your body quite fast for such blocky and odd movements, quickly regaining your feet, and taking a fighting stance. You knew you wouldn’t be able to beat this hashira yourself.
You took a deep breath. “Glitch breathing: first form.” You swung your sword over your shoulder, and the pressure around you cracked the windows around them. “Flame breathing: second form” Rengoku readies his blade for the strike. Glitch particles covered your body as you swung your sword from side to side in a quick motion. “Destruction Error” you exhale.
The chairs and the wood of the floor creaked, and cracks appeared. The wood burst. The debris was rushed at the flame hashira. Overwhelmed he dodged and cut through the debris of sharp wood pieces. Enmu took this opportunity to grab you into his arms once more and jump out the window. A meat tentacle sprung from his back and attached to the moving train. Pulling them onto the roof of the train.
“Well, that was something..” Enmu says. “We might have to jump..” she says looking down at the moving ground. You looked at him with a funny look. “Either that or we die to the demanding alpha…Your choice” he shrugged his shoulders. You sighed in frustration grabbed Enmu’s hand and jumped off. The flame hashira ran to where they were and jumped with them.
As you two were about to land, you unsheathed your sword, as you got closer to the ground, you swung your sword, the tip grazing the ground. The force you generated into the swing sent a gust of Dirt and plant matter at the flame hashira. Dirt got into his eyes and he fell on the ground roughly. You and Enmu ran off into the darkness of the woods.
“Names Enmu by the way! As you can tell I am a lower-ranking kizuki! Your name Is Yui right?” you side glanced at him. “Yeah..” you say softly. “Yui Nitchigama.. Nice to meet you Enmu” you say with a solemn tone. “Mount Natagumo shouldn’t be that far away.” You say. “Mount Natagumo? I believe that is where the lower five lives.” Enmu says, picking you up bridal style mid-run, then leaping into the air.
“I can walk, My legs work..” you say as you look down at the tree tops below. “You’re running on pure adrenaline right now, if you run any further you will collapse,” he says landing softly on the ground. He slowly turns and walks down the trail, you look on to see Mount Natagumo.
