I going to point something out so everyone will understand why isse I had vali train his as a dragon. In the Light novels and in the anime it is said that issei is more compatiable with his dragon but vali has more experience and more knowledge on dragons and fighting like one and fighting against them than issei does. This is probably why issei had vali train ixis instead training his son himself. But in my opinion Issei really shouldn't have let vali train his son all that much because now he's just as arrogant as him, or did no one notice his cocky smile in the summary.
