Apocalypse AnswerArms

Summary
In True Volume 3, Issei went together with Rias and Ravel to visit the Grigori establishment to meet up with Shemhazai and check up on Ryuuteimaru which had undergone a metamorphosis and wrapped itself in a red cocoon, changing from it's giant ship form to a new smaller form. Seekvaira Agares, who was one of the leaders of the Grigori Research Team of Ryuuteimaru, explained that Ryuuteimaru had changed it's form from a flying ship to a flying unit and added new weapons to itself as well as a hole which appears to be piloting control space. Ophis later appeared together with Lilith at the establishment to explained that Ryuuteimaru transformation is the result of Ryuuteimaru mixing together Issei's power, Ophis's power and Great Red's power as a result of being Issei's Familiar.

During the fight against Tartarus, Ophis and Lilith teleported to the battlefield, bringing along Seekvaira and the evolved Ryuuteimaru, which had completed it's metamorphosis. Issei combined with Ryuuteimaru which enabled them to achieve AxA. Using this form and Ddraig's manifestation, Issei was able to defeat Tartarus,.
