I like the sound of Issei and Gasper being connected. Too bad that may imply that Gasper does have feelings for Issei, lol.

But I think if Issei's Sacred Gear underwent some sort of evolution, it could become stronger than the Boosted Gear ever was. I mean Gasper's is changing so Issei's may take on a new change too.

The power to negate Sacred Gears is terrbile for Issei. Sure he can take down Magicians with his Dragonifcation and possibly his fire breath, but he can't go toe to toe with the major enemies without it in his current state. I get the feeling Great Red will appear again.
