Novel Playing With Other Supernaturals
This is the story where Urahara Kisuke died after Nel failed to save him inside Askin's Gift Ball Delux and reincarnated in the world of DxD.
I am not sure if I can capture Urahara's character properly so I apologize in advance if you are not satisfied.
Also, English is not my native language.
I don't own any of the characters from the canon.
