Transmigrating to the world of DanMachi, Ron always felt that the dungeons he explored were different from everyone else's. From the spawn point to the boss floor, a 365-mile journey without a single rest stop; dungeon monsters setting up crossbows on narrow bridges; the despicable Sixth Brother lurking in dark corners, writhing and waiting to ambush; the indispensable treasure chest monsters of the Soul Wanderer; hidden paths...

Who the hell raised this monster?! Dungeon: Yeah, who knows... (stabs hand)
