The World's Fastest Level Up

Years have passed since dungeons sprung up around the world. When adventurer 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!

There, he embarks on his most challenging quest yet, where he grows even stronger. Meanwhile, evil lurks toward his beloved sister Hana! What's Rin to do?

With even more levels under his belt, S-rank adventurer Kisaragi Claire approaches Rin in hopes of recruiting him to the Yoizuki Guild. Now, with a new opportunity to keep leveling up in hand, Rin's back at it, dungeon diving and surpassing all expectations. However, horrors lurk in the dungeons! Will Rin's Dungeon Teleportation and skills be enough to unravel the mysteries within?
