After a sudden appearance of “voids” 5 years ago, the world order went into chaos. A union of leaders from all around the world joined together to form a single government to serve and protect humanity. These voids created a rift between space, and through these voids came the monsters.

Suddenly some of the people started receiving power from which they can defeat the monsters which came through the voids, for these individuals were called “Adventures”.

These Adventures became the last line of hope, so Adventuring became the highest paying job. However, not all adventures were strong so an adventure world order was formed as an adventure’s guild and they gave ranks to all the adventures.

My name is Ron Stuart and F-rank adventurer. I recently received these powers and the adventurer who has ranked less than D has to visit the academy to learn the ways of adventurers and the only way to defeat monsters at my rank is to become an apprentice of an adventurer.
