I hope he uses spell binding circle to capture them all before teleporting home with issei and then calling Azazel to see if he sent them after him and see if he can get a favor for the information. Issei can become a devil if you want him too but, I hope you keep Judai as he is or maybe become a Full Flesh and Blood Duel Monster ( or whatever the heck the Supreme King is) instead of just a Duel Spirit or a Hybrid like he is now instead of a Devil (it's soo cliche anyway).
