In DxD with the Lancer Template

I am sick of it. Every time someone writes a story in the DxD universe, it's the same old garbage: building massive harems, reincarnating as that perverted idiot Issei, or becoming a lapdog for some devil. But if you strip away all that trashy fan-service, the actual lore of this universe—with its Biblical wars and clashing pantheons—is incredibly fascinating. So, let's change the script. There will be no harem here. There will be no hormonal, brain-dead protagonist. Instead, I transmigrated with the template of the ultimate badass from the Fate universe: the Lancer, Cú Chulainn, the Hound of Ulster. Expect the harsh brutality of Biblical wars, the blood-soaked legends of Irish mythology, and a protagonist who solves problems by driving his cursed spear through the hearts of mythological beasts, arrogant devils, and so-called gods. And romance? Forget the cliché high school girls. In honor of all the badass mentors who are always unfairly "friend-zoned" in anime... there is only one woman for me. The immortal Queen of the Land of Shadows, Scáthach. This isn't a high school comedy. This is a myth forged in blood.
