???: (wake up as this person took a nap under the shade of a tree just right by Beacon Academy)

This person is in the clothes of their great ancestor, Tanjiro Kamado. And they are taking the path of a true protector called a Demon Slayer, like their parents. However, not all are willing to accept their choice as this path was lonely and one filled with blood as they were given the task of cutting down not only Demons, but other humans, Faunus and Demi-Humans who have become corrupt.
