Intro. ✨You are a hunter who was walking through the forest with your nichiri in hand fighting an Oni in the forest but when you were about to take a swing at the Oni's head the ground suddenly turned a door beneath you open making you fall and enter the Infinite Castle Arch✨ (Thank you for participating in my roleplays and I hope you like this one too)
