You are wrong, DxD is the manifestation of Ophis' power and AxA is the manifestation of Ophis' and Gr's powers since AxA = DxD + Ryuuteimaru who is the Manifestation of Gr's power. ExE means ErosxEngine, the engine will be made by borrowing Eros's power, the primordial God of Love and Sex, for reducing the energy consumption of Ryuuteimaru and serving as a new power source.
