GetBackers: Dakkanya

Ban Mido and Ginji Amano run a freelance business of recovering anything lost or stolen from a client—and they claim a 100% success rate. They call themselves the GetBackers, and they're a super powered duo whose job lands them in dangerous predicaments. Although they have many adventures on their recovery quests, each has a mysterious past that rears its ugly head at the most inoportune moments. It's wild and crazy and one awesome anime ride!
