Hyoudou Ise, The Chichiryutei, Oppai Dragon, is the dragon that will protect the future...
Ise did tell to the past Sekiryuteis that instead of domination, he will show them the future. And after that, the past Sekiryuteis learn the feeling Oppai and the Oppai Dragon Song, which Ise finds it weird or he feels responsible.
Azazel also said that " Damn, I've never heard of a dragon who makes people happy with oppai."
I guess he'll be a unique dragon among dragons.
