[Western Crossover] Can a Nightmare Knight Have a Normal Love Life?

A drowned vengeful spirit who says one thing and means another × a straightforward-to-the-end Bruce

The drowned vengeful spirit, who should have died, not only receives a new life but also meets Bruce Wayne, who looks exactly like them but never became Batman. As the spirit vows to protect Bruce, they quietly fall in love with him.

Theme: Only by believing in yourself can you find salvation.
