Maybe the power of 12 heavenly breast + GR power = EXE form. Some time ago on twitter Ishibumi said that Issei will becoming the True Oppai Dragon and the girls turn into true oppai. Here what we know now about Issei's power: The Illegal Move Triana, CXC and DXD have triggered all Issei's pieces to turn into mutation pieces, according with Ajuka this could be realy change the world, Ophis and Lilith should be merged together in this way Issei can use again the DXD G but without dangers, the GR power is sleeping inside Issei's body. Issei have reach BXB and Triana touching Rias breast, and now trougth the Amrita he can use the Pseudo DXD for 88 minutes and can summon Ddraig for a short time after a countdown of 8 minutes. In the first volume of Shin Ingvild( the new girl that becoming his queen) have the power to controll dragons thanks her longinus and can increase the powers of the dragons using lavanda's particle when she singing. In conclusion Ajuka said that when Issei mastered the potentional of mutations pieces together with both GR and Ophis powers he should be reach AXA, and could get a taste of this power in this tournament.
