The Dorodoro Brothers' Provocation (3x9)

:

The Asmodeus and Sabnock pair and the Dorodoro Brothers were in the middle of hunting down a Hundred Flapple. The Dorodoro Brothers wanted to take back their master from Asmodeus and Sabro because they believed that they were their master's number one pupils. Both Asmodeus and Sabro end up falling for the brothers' provocation, but they didn't realize that the provocation itself had to do with the brothers' abilities. Asmodeus fights back by unleashing his evil cycle just the way Balam had taught him to. Also, what exactly is this history between the Dorodoro Brothers and their master?
