In a world where magic, monstrous beings, and power users are just mere fantasies of novels and creations of man's imagination. Jake Garcia—a 20-year-old Filipino male college student with a passion for Korean and Chinese cultivation light novels—finds himself inexplicably thrust into the realm of Solo Leveling.

After a tragic twist of fate and a single wish gone awry, he awakens in the body of Lee Joo-Hee, a B-rank healer who survived the "Double Dungeon Accident" along with the enigmatic protagonist, Sung Jin-Woo, and other character of the light novel.

Embracing his role, Jake utilizes Joo-Hee's memories to forge a new identity, strategically wielding the powers granted by his unique system. With a singular goal—to change Joo-Hee's fate of being a forgotten "side character"—Jake grapples with the haunting fears embedded within his new body, all while seeking to survive in a world teeming with hunters and dungeons.

Thrust into a new existence, will Jake still follow his reckless wish even though he is now the girl—he jokingly wants to become? or will he take another route and rise as someone who can never be forgotten in the world of Solo Leveling?

While being driven by an intense desire to win over Sung Jin-Woo and alter the course of fate, will Jin-Woo finally see through the facade and uncover the painful truth behind the betrayal of his so-called friend? or something else?

With every step, Jake faces the shadows of his own soul merging with Joo-Hee's, questioning the very essence of love and identity. The memories of his past collide with the legacy of the girl he inhabits, igniting a battle within that threatens to tear him apart.

As his powers grow, so do the shadows of endless life around him. Can Jake unravel the mysteries of this dangerous world while battling his own fears? What dark truths lie hidden in the dungeons, and will they lead to his salvation or doom?

Time is running out, and every choice could rewrite not just his destiny, but the fate of the entire realm.

In a reality where every choice could rewrite destiny, Banishment of the Anomaly is a gripping fanfic set in the Solo Leveling universe, weaving together adventure, action, and romance with a tantalizing layer of mystery. 

As Jake embarks on this extraordinary journey, he must confront the darkness within and outside him, all while seeking to forge a new reality from the ashes of fate.
