Manga Vanish (2022-)

Oliver Harrison was a mythical hero who slayed the greatest threat to his realm before even hitting puberty. But that was then. As an adult, Oliver leads an average cookie-cutter suburban life—aside from the fact that he's mentally unstable, massively paranoid, smokes like a chimney, and gets blackout drunk every night to hide from his horrific nightmares. Will the arrival of a superhero team called the Prestige prove the madness isn't all in Oliver's head? And what about all the epic fantasy crap from his childhood?
