In a world where interdimensional rifts are becoming a common occurrence, humanity has developed a new class of warriors: Fend Hunters. These elite fighters protect the world from creatures that invade through the rifts. However, Hiro Shin, an ordinary assistant to one of these hunters, never dreamed of joining the fight.

One fateful night, while working as usual, Hiro finds himself caught in the chaos of a rift, where a psychic entity attacks him. Instead of being consumed, Hiro awakens a mysterious power deep within his own mind—the ability to manipulate perception and reality itself.

With this newfound strength, Hiro's life is changed forever. As he grows more powerful, he must learn to control his abilities, but the power comes at a cost. His mind begins to fragment, leaving him to struggle with his own identity, as memories blur and new personalities emerge.

But Hiro isn't the only one with these powers. Others who have undergone similar transformations are after him—some wishing to help him, while others want to destroy him. As Hiro battles his inner demons and external enemies, he uncovers a darker truth about the origins of the psychic powers, leading him into a dangerous game of survival across multiple dimensions.
