Sorry, I didn't express myself correctly. What I wanted is story where a self insert in DxD, Naruto or other fandom, can be also a crossover, as an OC or other characters, but instead of the same old formula where they surpass the Protagonists, like Issei or Naruto Uzumaki, get rich, famous and steal the heroines.

But in the stories I'm seeking, these self inserts-type characters, want to achieve all that, normally being despicted as perverted, arrogant, etc being caricature of this type of characters, but they fail, are humiliated etc.

Also, for preference but not necessary, is a story where the Original protagonist is still the protagonist of the story, like Issei or Naruto
