Author's words: It is a combination of One Piece and Demon Slayer, mixed with some Fire Emblem (IF & ENGAGE) settings and original settings. The heroine has a certain strength when she first appears but is not invincible, and has a growth direction. The goal is to try our best to prevent all difficulties (but not everything can go as expected, just try our best to save).
There will be OOC characters, if you mind, please think twice before reading.
You may be slower, but you will never give up. Well, that's it.
Purpose: Work hard to become stronger bit by bit and resolve to protect humans from ghosts.
