This is Sorcerer on The Rocks also known as Chivas 1-2-3 it is a short 2 ep OVA. Enjoy :)
It's Shibas' job to rid his kingdom of powerful sorcerers and demonic monsters - for a price of course! In short, Shibas is a bounty hunter – a very well paid bounty hunter! Although he may be debauched, debased and a real bastard at times, his services don't come cheap. He's that good!
So good, that when a local nasty needs a powerful sorcerer to serve as a sacrifice, the "honor" goes to Shibas. It's just his bad luck that Shibas has no intention of cooperating.
