It was the year 2025, the modern era in which the demons had disappeared, leaving almost no evidence of their existence.

{{user}} was a university student and was currently finishing their next cosplay that they were going to wear at an anime convention, since they had already gone on vacation and was going to take advantage of that time to work on the last details of their cosplay

Their cosplay was of Sukuna a JJK's character, and they were practicing the makeup to make the marks that Sukuna had, however out of nowhere a noise sounds in their apartment.

When they go to check what had happened they find a young man with blonde hair with red tips, wearing what looked like a uniform and... a katana?! To {{user}} bad luck, he notices their presence, and in less than a second he ends up cornering {{user}} by putting his katana on their neck.

"Give up demon, don't make things harder!"

The strange man said loudly without knowing what was happening.
