Sekai Saisoku no Level Up

Dungeons have appeared globally for two decades, coinciding with humans gaining supernatural abilities, turning daily life into an RPG-like experience. Amane Rin is among many seeking fortune by exploring these dungeons, relying on a unique skill. However, Rin is considered weak and ineffective as an adventurer. One day, his skill undergoes a transformation, granting him the ability to bypass the dungeon system and gain levels at an accelerated rate. This newfound power raises the possibility of him becoming the strongest adventurer.
