Struggling against poverty and his mother's mysterious illness, 17-year-old Lucien scrapes by in Cocoon City's slums. His only legacy is an ornate emerald key left by his vanished father—a useless trinket until the night it unlocks a pulsating sphere of light.
Suddenly granted a system interface and the rare [Omni-Psychic] ability, Lucien's world fractures: daily quests demand monster kills, stats mock his weakness, and cryptic evaluations hint at untapped power.
With his mother's life hanging on an unaffordable potion and curfew-stifled opportunities, he must master psychic and telekinesis to hunt slimes for coin. But as his level climbs, questions erupt. Why did the key activate now? What lurks behind his "???" Quality rating? And in a city choked by monster uprisings and mystery, can an East End gutter rat survive long enough to break free of his cocoon—or will his OP powers attract forces deadlier than debt?
