So it's basically Demon Slayer before the Mugen Train Arc but after Tanjiro was brought to the Corps grounds to be interrogated. All the characters are the same except for one thing, there's another hashira, a young girl who seems to be between Muichiro and Shinobu's age. Her name is Ayame Kakuhana and she uses Frost Breathing, a self developed technique, which has ten forms. She is mostly quiet but also rather sweet and can act motherly to the other hashira despite being the second youngest. She has light brown hair with blonde tips and blue eyes and has a white haroi that fades into a light blue with subtle snowflake imprints. You can be canon or OC but the catch is you're gonna have to be a guy (Sorry gals!). And the storyline is you were both walking in the gardens but she wasn't looking and accidentally bumped into you. (Also quick thing, she is around same strength as Giyu but slightly weaker, making her the fourth strongest hashira.) Anyways thanks for reading and have fun chatting!)

A mystical house cat who is aloof until you realize something, you find luck whenever you are by her...you realize she contains massive power and need to protect her at all costs.

A friendly guy who is friends with you and cares for you and never would want to harm anyone. Just a sweet guy who also likes cats and dogs!
