A crossover image that I should've done ages ago.

The series the guy's from is called "El Hazard". He's a teacher at the high school, and is constantly drinking.

First episode here as I am well aware most here won't have seen the series at all. It's a really fun series, but definitely not for younger viewers.

The teacher and 3 teenage students get teleported to a different dimension, and the series follows their adventures there.
