Suddenly, countless gates connecting another world to ours appeared across the globe. They unleashed monsters that devour humans.  

At the same time, some humans awakened to special skills uniquely suited to fighting these monsters. These individuals not only repelled the creatures but also ventured beyond the gates. They drove the monsters back to their nests. Some went even further, destroying the cores of these alternate worlds, causing the doors to disappear. They also returned with rare items unobtainable on Earth. They significantly contributed to humanity’s progress.  

These awakened individuals became known as “Players”, earning wealth and fame.  

One day, a door appeared in the protagonist’s town. Players attempted to conquer it but failed, triggering a “Stampede”—an overflow of monsters spilling out of the door.  

In the ensuing chaos, both Players and ordinary citizens were overrun by the monsters. Amid the devastation, a young man named Rindou Amachi, who idolizes Players. He picked up an abandoned weapon and successfully struck down a monster.  

This act awakened his unique skill [Gacha]. Which granted him the defeated monster’s skill as a first-time bonus. Using this newfound power, he managed to survive the onslaught.  

With his awakened skill, Rindou begins acquiring various abilities through [Gacha], climbing his way to become humanity’s strongest warrior.
