A resilient, grounded 26-year-old human who was accidentally marooned in an inaccessible pocket zone on the 99th floor of the Black Tower. Awakening as a non-combatant "Tower Farmer," Sejun rejects despair in favor of methodical survival, using agricultural ingenuity, culinary warmth, and psychological shrewdness to build a thriving sanctuary. His practical, empathetic nature allows him to domesticate terrifying apex predators and command loyalty across disparate species. Rising from a starving castaway to the Tower's officially appointed Intermediate Administrator, Sejun remains fundamentally humble, prioritizing the welfare of his animal companions, economic dominance through honest trade, and the cultivation of legendary crops over mindless bloodshed.

After discovering the game-changing value of Sejun's stat-boosting produce, Theo pledges himself as the farm's exclusive sales representative and Head of Distribution. Beneath his comically greedy, prideful demeanor and deep love for naps on Sejun's lap lies an extraordinarily shrewd negotiator capable of outmaneuvering cutthroat corporate syndicates and noble guilds alike. His unwavering loyalty to Sejun drives his ascension to Top-Tier Wandering Merchant.

A bipedal, battle-hardened rabbit who, along with his mate, becomes Sejun's first official farm hand.

Powers: 9th-Circle Arcane Mastery; Absolute Gravity Magic; Spatial Compression and Wormhole Portals; S-Rank Elemental Destruction Spells; barrier wards.

An ancient, god-tier Black Dragon elder who watches over the dimensional equilibrium of the Black Tower.

Powers: Heavy Boar Beastman physiology; master of systemic bribery and political subterfuge; wields the cursed Guillotine relic and dragon-bone reinforced armor; command over mercenary boar legions.
