Bel

Bel is the leader, as well as the oldest member of the Selfish Trio. He first appears in Episode 3. Bel has a gray beard and moustache, with his hair combed backwards. He wears glasses and a black coat with green lining. His eye color is olive, the same as Ira's and Marmo's.

Bel is an extremely lazy person who does not really enjoy doing any work himself rather he sends Marmo and Ira to do all the dirty work.
Despite his seemingly calm and cool demeanor it has been shown that he has a sadistic side when he tried to torture Cure Heart by taking Ai hostage and thus making her unable to fight back or when he set up a trap for Mana and Regina trying to make one of them betray the other and let her fall into the lava. He also has no qualms on killing other members, namely Leva and Gula, taking joy on their painful deaths.
