1. Arrival

In the world of demons, there are no mercy. No life to be spare. Either kill or be killed. (Y/n) knew that perfectly well and that's what she had taught to Tanjiro. She just hoped that this world could somewhat be different from the one she came from.

Apparently, Kira does not think so.

Thankfully, the great detective L is here to save the day.

Unfortunately, (Y/n) is just the Sun Hashira that accidentally caught up between these messes.
