Alongside the MCs the only characters that I remember that is confirmed that will appear are:


 * Vali team(to help Arthur with the longinus user problems, included Kuroka),


 * Crom(interested fake heavenly dragons)


 * Sairaorg because Ishi said that.

Ishi put him as Issei parents bodyguard.. So. I am not sure if he can appear in the next volume (I can be wrong in that)

VERRINE WANTS TO FIGHT AGAINST ISSEI.(Tobio can´t fight against her and after use him in Shin 3 maybe is not in this volume).. But Issei can fight against Hades and Verrine in 2 separated moments in Shin 4.

SHIN 4 IS ONE GOOD VOLUME FOR VALI FANS according one of his tweets.. He can probably fight against Angra Mainyuu.
