"Kujyou Haruto, you're the current failing-at-school past me, right?" someone overheard saying to him."This is a prophecy from the future," "You will be a mage who can control space and time in the future," "Just follow my instructions going forward," and so on. Thus, despite his misgivings, Haruto chose to enter the Shinjuku Imperial Garden F-Rank dungeon. And there it was! A secret room that's unknown! #manga #manhua #manhwa
