The Witcher of Kuoh (Male Witcher Reader x Highschool DXD Harem)

(Y/N) was a Witcher in the Kingdoms. But when tracking a Monster, (Y/N) was transported into a world where Fallen Angels, Devils, Angels and Sacred Gears exist, but monsters like Griffons, Werewolves & Nekkers don't. Now, in a world that's slowly being invaded by the monsters from his world, (Y/N) must help the people of the Supernatural to defend their world. However, with several girls falling in love with (Y/N), betrayal could occur.
