SSS-Rank Awakening: My Infinite Absorption System

Nineteen-year-old Fin has one plan: work the packing line, pay rent and keep his little sister safe in a city where hunters are gods. He tested for powers at fourteen but nothing happened. Then a broken gate tears open in his alley, an orc caves in his chest, and a playful goddess offers a dying nobody a deal she never finishes pricing. Fin wakes up carrying a system no hunter alive has ever had: kill it, touch it, absorb it. Every corpse pays out stats. Every monster makes him permanently stronger. In one night he goes from unranked to E-rank, leaving questions behind him... a faceless woman who saved his life, a hero already pulling his file, and whoever forced that gate open on purpose. The ladder above him runs seventeen ranks, and every step costs more than the last. Fin's system doesn't care what things cost. — Description from novelcodex.org
