Choujuu Densetsu Gestalt

- Similar style of comedy, but Excel is more extreme. - There's a "commander" character who stays in a building who sends a girl(s) to a mission. - The heroine is blindly in love with a guy and would do anything for him. 

Both "Gestalt" and "Chivas 1-2-3" center on over-powered sorcerers, Ohri and Chivas respectively. They both appear to be rather self-centered and with ulterior motives. Both anime include the theme of slavery, in "Chivas 1-2-3" Chivas appears to have the two female main characters, Fizz and Kiss enslaved to him; both treat him as a master. Likewise, in "Gestalt" Father Olivier is "given" Ohri as a slave, who treats him as a master. Both these shows deal in showcasing magical battle fireworks. They're also contemporaneous classic 90's OVA, if you're looking for that kind of thing.  

Both are short, fantasy comedy OVAs that never really got off the ground - but well worth spending an hour on if you're in the mood for something lighthearted and none too taxing on the brain. Gestalt only differs in that it's more modern animation holds up slightly better. That and the humour isn't quite so broad as Dragon Half's. 

Good fantasy line, somewhat similar relations.  

Light-hearted fantasy with a tongue-in-cheek approach to the usual clichés.
