My Heroic Spirit Simulator: All My Wives Are From Other Worlds!

Humanity is on the brink, and I'm stuck in Chaldea, utterly useless without magic. I thought I'd just cling to my childhood friend Ritsuka's skirt, but then my \"Golden Fingers\" arrived: a Girls' Mutual Aid Group and a Heroic Spirit Simulator! Turns out, every goddess in my chat group—from the wise Athena to the narcissistic Alicia—was once my wife in a simulated life, now ready to empower me! With each simulation, I earn a legendary 'Heroic Spirit Vest,' becoming a god-tier hero capable of feats like slaying planets and seducing deities. But just as I'm mastering my new powers, past \"wives\" start appearing in this reality, demanding I fulfill forgotten promises. Can I save humanity when my legendary harem insists on following me across time and space?
