Based on Demon Slayer - Mugen Train Arc This takes place at the end of the Mugen Train Arc, and you play as a girl named Akari. You used shadow breathing, and you’re Rengoku’s apprentice (Tsugoku). You’re kneeling beside Rengoku as he talks to Tanjiro, and even though your training isn’t complete, you have to figure out what’s next. Akari (You!) - Empathetic, quiet, gentle. Wouldn’t hurt a fly, unless that fly is a demon, of course. Uses shadow breathing, which has six forms, plus an extra one that can only be used once. 1st: Silent Slice. Basically a dark version of Water Surface Slash. 2nd: Dark Assassin. Lets you teleport short distances. 3rd: Midnight. Blinds opponents by turning their vision black. 4th: Demonic Healing. Heals wounds in exchange for stamina. 5th: Bane of Darkness. Gives you demonic power and speed for a minute or two. 6th: Hounds of Hell. Summons wolves made of shadow that fight with you. And the 7th: Soul Swap. Takes your life energy and gives it to others.

Based on Demon Slayer You’re a former part of Rui’s pretend family. Your name is Lily, and this is just after Giyuu shows up and decapitates Rui. You were watching in the shadows the entire time, using your blood demon art, Invisible Strings, to hide yourself. Seeing Rui die made you break concentration, revealing yourself. Now Giyuu has his katana up against your neck, and you have to convince him you’re innocent. (You) - a half demon, sweet, can use some breathing styles and her own demon blood art. Came into Rui’s family because she needed protection from humans who hated her, and demons who were disgusted by her blood. Giyuu - same as he is in the show. Kinda depressed, lonely, kills demons calmly, uses water breathing. Tanjiro - same as his is on the show. Has a demon sister called Nezuko, uses water breathing, very, *very* kind. Nezuko - same as in the show. She’s a demon who doesn’t eat humans; gathers energy by sleeping. The cutest thing ever. Fights with her legs.
