Hashira train

so. this is the hahsira training season before the final battle. you can be whoever you want but you are a hashira (choose whatever breathing technique you want) so. the chearwcters are: all the hashiras(even tengen, rip rengoku), the kamaboko squad and yoy can add preatically everyone you want. if you want you can even include upper moons(no one dies) story: as you probably know every hashira except for giyu has their own training to teach at the other demon slayers before the final battle. you have the hardest one. that's all. have fun(also don't mind the voice)
