Task Force: DXD (Male Reader X Highschool DXD)

After a brutal clash with a rogue Fallen Angel General on a speeding train in Queens, Y/N, a battle-hardened swordsman wielding a blade imbued with fiery power, finds himself reassigned to Kuoh, Japan, at the request of Sirzechs Lucifer. Tasked with protecting and guiding Rias Gremory and her peerage, Y/N is thrust into a world of high school life, supernatural conflicts, and unexpected romance. As he navigates his new reality, old enemies resurface, hidden conspiracies unfold, and Y/N is forced to confront his past while forging new bonds. He must decide-will he remain a lone warrior, or will he finally find something worth fighting for beyond the battlefield?
