[Divorce-and-Rise Story] [System] [God-Tier Battle Maidens] [Decisive and Ruthless] [Feel-Good Story] [Multiple Female Leads] [Scheming] [Subtle Romance] [Post-Apocalyptic Setting] My S-rank campus-beauty girlfriend publicly calls off our engagement, leaving me an F-rank loser. But then I unexpectedly discover that piloting battle maidens in this world isn't as simple as it seems! Entering a battle maiden's cockpit is like entering the most private depths of her heart! What's more, I've awakened the [Villain Emotion Plunder System] and the SSS-rank talent [Wheel of Fate]! While everyone mocks me for signing a contract with an abandoned E-rank delinquent girl, I've already “entered” her lonely inner cosmos and awakened her true form as the [SSS-rank Phantom Demon God]. Later, the gentle Teacher Su comes to me, blushing. “Student Li, my [Hawk-Eye Sharpshooter]… it's longing for your power.” Even the beautiful principal, whose deceased husband's battle maiden [Eternal Holy Shield] remains frozen, issues her most intimate command in an unyielding voice: “Li Qinghai, enter my Holy Shield and let it… feel its heart beat again.” When my ex-girlfriend comes crying and begging me, I smile. “Sorry, my cockpit's full. Besides, every single one is an SSS-rank that can evolve on its own!”
