Ajuka explained in volume 23, that Ophis and Lilth needs to resonated and Ise needs to awaken GR power in order to use his true DxD mode without problems. I guess, that when Ise master his true DxD mode and find away to combine Ophis and GR powers, in this regard he could unlock his AxA mode. But as I mentioned Vali and Ise needs to strengthen their base form, because they need to master CxC and EMJ.
