The Novel's Extra
Ji-Gab-Song
Waking up inside the world of his own novel, Hajin Kim finds himself as an extra at Cube — the prestigious floating-island hunter academy that trains humanity's defenders against Djinns, dungeons and dimensional phenomena. Armed only with his foreknowledge of the original story and a unique Gift that lets him interfere with the narrative, he must manipulate events, outwit the true protagonist and rising powerhouses, and survive a curriculum where hunter ranks, Gift grades and dungeon clears dictate survival. Each volume escalates through Cube's semesters, field missions and world-scale phenomena, rewriting fate one chapter at a time.
Progression: Cube Academy Hunter Rank & Gift-Grade Progression. Central ladder is Cube's hunter academy: cadets advance by semester, rank exams, and field deployment, with explicit hunter ranks (low-grade to high-grade hunters) and Gift grades (F to SSS) that gate power. Protagonist Hajin Kim progresses via Gifts — notably 'Deus Ex Machina' and 'Master Sharpshooter' — that level and evolve, plus Stigma magic, SP investment, and dungeon/phenomena clear tiers that reward stat growth and new artifacts. Story tracks Artifact collection, Magic Power circuits, and meta-narrative 'Story Correction' where interfering with the original plot yields quantifiable reward penalties/bonuses. Each volume corresponds to academy terms, rank promotions, and World After Fall-style scenario escalations, verified via Goodreads series grouping (Vol 1-12) and publisher descriptions tagging academy hunter progression.
