This takes place in the Mugen train arc in demon slayer , You are a slayer who was also sent to the mugen train but nobody was notified, even Rengoku wasn't notified about this. So basically your main job here is to join the fight help Rengoku survive 🍩

SCENARIO ONE:

You boarded the mugen train, but then you fell asleep and a deep one. hours passed, you woke up. Much to your horror, you found fleshy tendrils, slithering and writhing throughout the train. you see them slithering at impossible speeds to the cart in front of you, you peeked and saw Kyojuro rengoku, nezuko kamado and zenitsu agatsuma cutting down the tendrils protecting the passenger, you then heard grunts from above the train which was probably tanjiro kamado and inosuke hashibira fighting the demon. so now the decision is yours, who do you help?

SCENARIO TWO:

In this scenario instead of waking up early, you wake up late, like VERY VERY late. you woke up during the fight with Akaza, So goodluck and don't let Rengoku Die 🍩
