I Arrived in the Ghost-Faced World from the Start and Cleared the Hundred-Story Ghost Tower

I came to the Tower of Ghost Faces.

This is a place where criminals are exiled. All those who show contempt for life will end up here.

But I... can't remember anything.

I have to clear all one hundred floors of this tower.

But... something seems wrong here.

Am I... really a criminal?

(Just treat this as a simple, beginner-level story. There aren't many hidden clues, the writing isn't very good, and you might not like the plot, but that won't stop me from continuing to write.)
