AxA is basically Ise in Pseudo DxD G (Black armor is manefistation of Ophis power of infinity) piloting evolving Ryuteimaru (manifestation of the answer to Great Red power).

AxA mean - Apocalipse Answerarms (Answe + Arms)

Tartarus is 100 meters Ball with many eyes and tentacles. He is Primodial God of Abyss. Abyss is the world of darkness where is no light at all. Tartarus target is to seal all Longinus possesors into Abyss (cause if kill them Longinus just reappear in another possesor)

In AxA mode Ise has several moves:

1. Revelation Barrier - basically just a very strong barrier around whole body. Tartarus attacks couldn't penetrate it.

2. Revelation Blade - in AxA form Ise (his megazord) has four arms with Aura Blade in each hand. This blades calling Apocalipse Ascalon

3. Revelation All-Range Blaster - same as in Bioshop Triania, CxC, DxD forms - finishing move. Aura bombardiment that is strong enough to blast away more than half of Tartarus body. Has infinity and dream.
