I don't usually read DXD fanfics, as they are usually somewhat boring, but this is gold in a coal mine, that Chinese touch although it is little makes me feel like in MTL, but as if it were not there, it feels good.
The MC is already a step below the peak of the mortal realm. Only certain people who touch the transcendent realm can beat him. And sorry Issie, that doesn't include a Heavenly Dragon that at most can match our current MC.
You know mc can’t kill issei but he can still rip off issei hand or leg or maybe his third leg right? As long as mc didn’t kill issei he can do whatever to issei so why don’t just rip issei balls and turn him into eunuch?? 😂
