First of all, ImperiexSeed, I had already told you multiple times not to answer other people's questions. Stop. And for the anon, the Knights of Hell aren't stronger than archangels, they just can't be killed by them. Btw, Lucifer didn't make them, Cain did. It isn't an opinion for you to have, it was confirmed that the Knights are the strongest demons.

Again, there IS proof that archangels can be killed by leviathan. A writer confirmed it for us, which is proof.
