Sekai Saisoku no Level Up

It has been twenty years since dungeons began appearing all across the world, an incident that coincided with humanity receiving supernatural abilities–all of which turned everyday life into an adventure. When Amane Rin awakens to a unique skill called "Dungeon Teleporting," the rules can't touch him anymore. This is the tale of how he races to become the world's strongest (and fastest-progressing) adventurer!
