Sometimes it seems that any Devil, outside of Sairaorg and maybe Diehauser, was content to have his Powers that he was bestowed at birth and did only train what was nescessary. Issey Generation seem to be the Kind of Devil which is training extreme and grow because of that and because of their Experience from their Fights.
