Heavenly || Muichiro x Reader

── ❝ I know that I already disappeared from your heart. But please, don't forget my name. ❞

After y/n returns from their short break, they were only to witness a sicking scene where their loved ones die to blood thirsty demons. This leads y/n to fall into deep despair and give up on their life, only to be saved by a boy. Soon learning that the boy works under a corps called Demon Slayer. But before y/n could even show their gratitude to the boy, he suddenly vanished. Being driven to determination, y/n decides to work under Demon Slayer corps while having two goals in mind. First one was to help avoid individuals to experience the same pain y/n had to endure, and the second one being about meeting the boy who saved y/n to thank them personally.

As time passes, and y/n finally get noticed by the higher ups called the Hashiras. Being spotted from them, y/n coincidentally gets chosen by the Mist Hashira to be his tsuguko, who goes under the name of Muichiro. Turning out to be the same person who saved y/n many years ago. This gives y/n the advantage to get know Muichiro better, only for it to blossom a complicated relationship between each other.
