 * If you're talking about Issei's life-span being short as a result of using Juggernaut Drive in vol.6, then that is no longer an issue. After Issei gets a new body in vol.12, his life-span should be nice and long. In fact, since dragons have limitless life-spans, Issei's should be the same.


 * As for the nurfed power thing. Issei gets a new power-up in vol.21: DxD G. It's basically Ddraig's power (within the Boosted Gear) and Ophis' "infinity" power (within Issei's body) fusing together, resulting in a new, more powerful form for Issei's armor. However, Ophis' "infinity" power is too much for Issei's body to handle, resulting in him needing life-support after he deactivates the form. In fact, the only reason he can even survive using it is because his new body is made from Great Red's flesh. Ophis nurfed the form by removing the "infinity", at least until Issei trains his body to be able to handle it.
