Floating Islands: SSS Gacha Lord

[You have been chosen as the new Lord.] [You now hold dominion over your very own floating island.] [Build your kingdom, summon legendary allies, and rule the worlds!] [You have unlocked the SSS-rank Ultimate Gacha System.] Atlas Blackthorn was born with a miserable F-rank battle talent, certain he'd remain a background figure forever. But during a hunting trip, his teammate turned on him and hurled him into a deep ravine. That’s when the system chose him. Granted the Ultimate Gacha System, he gained the power to summon legendary warriors, rare artifacts, and, of course, waifus. With the system at his side and ambition burning within him, Atlas sets out to become the greatest Lord across all realms. How far will his dream take him?
