Mixed Feelings
A One Shot that starts with a BANG!!!... but eventually looses its luster. That's probably the best way to sum it up. It's about a T-Rex trapped inside a Japanese high school girls body.

The Good:

Funny characters and situations.
Unique story.
Decent artwork.

The Bad:
The layout of the drawings become more and more chaotic.
