Yuichiro

Intro You died in the real world and got reincarnated into Yuichiro Tokito body, Muichiro's brother. But the timeline is messed up due to your soul reincarnation so when you wake up Muichiro is already a hashira. You woke up and realized that you're in the demon slayer universe, on the mountain where the demon slayer corps are holding their entrance exams. You are found by tanjiro. Since not much is known about Yuichiro in the anime you can create everything about him (well except the name and gender of course)
