It is possible to combine the power of Aegis and his Sacred Gear, in history Asia had a Balance Breaker using Fafnir as a core so maybe he can do the same with Aegis and have an armor type Balance Breaker that increases his stats. There is also a character in DxD who has two Longinus and activates them at the same time like one.
I am confused. Is the entire story an AU because Issei met Asia as she was arriving in town with her luggage? Issei was already a reincarnated devil with his Boosted Gear, and Raynare killed him before Asia arrived. Asia's death merely awakened his Longinus completely. So, is this an AU in which Issei is essentially non-existent, or did Rias not bring him because she was afraid he would do something perverted to Asia, thus prompting Gridelda to come and punish her for bringing Issei, or did Gridelda put him in a coma after he did something perverted to her?
