Help I Changed The Plot Of Demon Slayer

It's basically a fanfiction about my nonbinary, intersex, and asthmatic OC named T being a massive fan of demon slayer in their world, and one day while rewatching the show (ep 3, s1) they literally get sucked into the screen and land in the Demon Slayer universe. They are found by the flame hashira, Kyojuro Rengoku, and the sound hashira, Tengen Uzui. T makes a goal to become hashira level as soon as possible so they can save Kyojuro from Upper Moon 3, and make some killer friends along the way!

FUN FACTS:
The asthma is minor/mild
They have heterochromia (right blue eye, left red eye)
Pronouns are they/them ONLY
Memorized every Imagine Dragons song, and wrote them down too
Liked to run but due to a homo/transphobic state, they couldn't do cross country
Infertile
Speaks their mind, is NOT afraid to humble somebody
