Freeze Them All

I'm a little wizard and

A chaser who catches monsters which have escaped from the magical world.

The magic I use is ice magic.

I can freeze anything just by touching it with a potion.

But there is one weakness.

Monster can't solve magic on its own, but other monsters can solve it.

Anyway

Shall we start now?

Ah... wait. I have to dress before I leave.

I actually just graduated from magic school.

I can't go around in training clothes.
