[Demon Slayer] The Demon Slayer Eventually Becomes a Demon

"Master, I've figured out what suits me! Why can't there be a Breath of Demons?"

"???"

"I've decided. I'm going to become a Demon Pillar!"

"That's not what I meant, Master. If people can turn into demons, then surely demons can turn into people, too, right? Whether it's real or not, can't we make use of them? In the end, they're all just means to an end. As long as we claim we have a way to do it, we can solve a lot of problems."

Including war.

"Master, I've already made up my mind. I'm willing to become a demon."

"So I can wipe every evil demon from the world."

This is the story of a Demon Slayer Corps swordsman who dreamed a youthful dream, managed to turn himself into a demon, and actually made that dream come true.

1. The protagonist's true form is a Higanbana, but not a blue one.

2. Quite a few liberties with canon. For example, I have to let my senior brothers and sisters live.

3. Pairing: Sabito.

Theme: Freedom, happiness, forgiveness, and a radiant life are all indispensable.
