Mysterious dungeons have appeared all over the world, and adventurers, chasing dreams of getting rich quick, begin challenging them. Sora Amami, a bottom-of-the-barrel F-ranked adventurer, has had his weapons stolen from him by some high-ranked adventurers. But as a result of something strange that happens to him, he becomes able to see his “status screen”. Moreover, he obtains a skill that provides him with a 100% drop rate of any items that surface during a battle with an enemy. So by being able to adjust his status and make full use of his skill, he aims to level himself up from being the weakest to the absolute strongest!
