Sunkissed. (Megumi Fushiguro X reader)

The unidentifiable, uncharted island of Oandit is infamous only among a select niche of people in the world: Curse users. Having never been colonized nor overthrown by neighboring countries, Oandit is completely off the grid. However, their wealth, power, and status are incomparable to any other because of a globally passed myth:
Their labor force, including the military, is made entirely of curses.
And the "Discipline General" who is training these curses is a woman named Y/n.
With the ability to capture, store, and command curses, she walks the mainland scouting for the most powerful curses because they are the largest energy source.

Then one day, she heard a myth that points her direction to Japan: The largest energy source, one that could power the island for hundreds of years, can be found in a young man about her age, named Sukuna.
