Sent to Paradis Island a year before the Colossal Titan breaks Wall Maria, Y/N Tybur is a spy sent by Marley to infiltrate and locate the Founding Titan by any means necessary. All he has with him is a knife, a gun, his wits and the WarHammer Titan power.

A forgotten dragon, exiled for being the weakest of them all, returns with a vengeance, to prove her worth to the other dragons. Y/N, an ordinary boy with no special talents, a new resident in Kuoh town, arrives to start a life on his own. What do they have in common? Nothing at all, and yet both will meet each other and change each others' lives for the better. *I do not own Highschool DxD and all media I use is not mine.
