Those vile creatures are the epitome of foolishness.

Choosing the dark side when you can gain strength with a normal, difficult but pure path.

Huuuu...

Then, there was you." she stopped and looked at me with an impressed, intrigued, and joyous expression.

This was pure joy as if something she had never thought was possible had happened before her.

It disgusted her when talking about that slime and creatures like it, but there was a stark difference when it came to looking at someone like me or Celes.
