Alga was kicked out of the party he was in because he was a tamer, an unpopular occupation,and took this opportunity to get his level checked again at the adventurer's guild,where he discovered he had a second job that appears only once every millennium:A "tamer" who befriends monsters, and a "mixer" who combines monsters to make them stronger. With these two jobs, Alga will create the ultimate party with monsters, the world's strongest female adventurer, and the vampire princess!
