The Novel's Extra (Remake)

Waking up inside a world you created might sound like a dream, but for author Kim Hajin, it quickly turns into a living nightmare. Without warning, he finds himself transported straight into his own web novel—not as the invincible protagonist or a revered hero, but as Chundong Kim, a completely nameless, talentless cadet at the elite Cube Hero Academy with no presence in the original plot. Armed only with a gun in a world where everyone else wields swords and magic, and possessing an omniscient author's notebook that grants him SP for influencing the storyline, Hajin must navigate the deadly dangers of academy life, demonic threats, and monster invasions. But as unexpected plot deviations and mysteries begin to unravel the narrative he thought he knew, surviving until the final chapter becomes a battle against fate itself.

Originally an ordinary web novel author, Hajin is transmigrated into his own story as a low-ranking extra cadet. He is highly pragmatic, cautious, and burdened by his meta-knowledge. Operating primarily from the shadows, he acts as an unsung guardian to prevent his creations from meeting tragic ends. Powers: Wields the "Settings Intervention" authority to rewrite object properties. His primary weapon is a customized Desert Eagle that transforms into a sniper rifle, augmented by his master-grade marksmanship. He utilizes "Stigma" to store star-mana for physical enhancement, barriers, and homing projectiles. Later, he operates under the terrifying mercenary personas "Black Lotus" and "Marang."

The destined main hero of the original novel. Suho is the epitome of virtue, courage, and justice. Guided and protected by Hajin’s subtle behind-the-scenes interventions, Suho grows into an unstoppable martial force committed to defending humanity. Powers: Possesses the supreme "Sword Saint" talent, giving him unparalleled mastery over blade arts and sword-qi projection. He later awakens and wields the legendary holy sword *Mistilteinn*, which grants him massive anti-demonic capabilities.

The fierce, short-tempered, and highly competitive heiress of the powerful Daejin Group. She struggles with immense emotional trauma after her family is struck by tragedy, transforming her from a proud rival into a vengeful warrior hunting her brother's killer. Powers: Originally trained in archery, she transitions to high-output swordsmanship after Hajin privately points out her true affinity. She possesses massive raw mana reserves, allowing her to project destructive, long-range blade energy.

The quiet, duty-bound Princess of England and a top-tier cadet at Cube Academy. She carries the immense weight of restoring her nation's fallen Royal Guild and protecting her people from hostile foreign elements and Djinns. Powers: An elite elementalist specializing in rapier-based combat. With Hajin's secret guidance, she unlocks her dormant "Spirit Summoning" potential, allowing her to command powerful elementals to turn the tide of high-level battles.

A brilliant, calculative, and highly ambitious cadet who rises to become the successor of the prestigious Essence of the Strait guild. She values information and efficiency above all else, using her razor-sharp intellect to manage corporate and political landscapes. Powers: Highly proficient in whip-based combat and mid-range crowd control. Her primary strength lies in her high intelligence, organizational leadership, and near-peerless asset management.

A sweet, innocent spirit child born from the Butterfly Sapling artifact on a remote testing island. She is incredibly attached to Hajin, whom she views as her father. She initially suppresses her own growth out of fear of being taken away from him. Powers: An incredibly high-potential summoner capable of creating and commanding magical spirit beasts. Under Hajin's nurturing, she learns to unlock older forms of herself, gaining massive stat boosts and the power to conjure mythical-tier creatures.
