Reborn as a Demon Lord with a Gacha System

Kael, a corporate drone, dies a pathetic death only to awaken as a newly spawned demon lord in a brutal fantasy world. Gifted with a 'Gacha System,' he can summon legendary heroes, monstrous familiars, and world-shattering artifacts by spending 'karma' points he earns through conquest and chaos. But this power comes with a terrifying catch: every summon risks drawing the attention of the 'Divine Conclave,' a celestial pantheon hell-bent on eradicating all demonic influence. Kael must not only build his dominion from scratch amidst warring factions and ancient evils, but also outwit the watchful eyes of gods while grappling with his own burgeoning demonic instincts. Can he forge an empire and survive, or will his gacha addiction lead to divine retribution?
