Hmmm, I wonder if the world is trying to correct MC's influence on Rias and the other DxD girls? Basically, "hearing MC's inner voice" would pretty much remove Issei's chance of being a protagonist. To correct this, a future version of himself was brought back to compensate. This may be how MC can kill protagonists. The heroines hear enough to cause a butterfly effect. When the protagonist loses his ability to become one in the first place, the world corrects it. However, now the changes from the world make them no longer "canon" protagonists. This leaves them vulnerable to being killed without the reset.
Just today I started reading this fanfic and I sincerely thought it was going to be *cliché* but what a surprise I found. As the saying goes: "I went into the mine looking for copper but ended up finding diamond". equally putting that aside i wish the mc didn't care so much about the plot and make a move once and for all i kinda don't think the world resets with everything that's happening to currently, so with all that he should already realize that he can kill issei without repercussions . Anyway, keep it up author, this is a great story 👍
I honestly imagined that MC would have thought about killing issei to stop his inner voice transmission. And maybe treat heroines as just some kind of dolls without will at the start of the fanfic so there will be more space for character growth and some extra drama. But whatever, it's still good fanfic nonetheless.
