[Not a harem story or a multiple-couple story, just a funny Batman-saves-the-world tale about being duped by a "System," with no romance!!!]
Bruce has lost his memory. He doesn't remember who he is or what he's been through. The only thing he knows is that when he opened his eyes, a crowd of people was gathered around his bed, all claiming to be his children.
But that's not the scariest part. The scariest part is that he seems able to travel between two worlds.
In World A, the amnesiac Determined One leads a group of monster kids, struggling to survive the apocalypse while fighting for control against the "Sickly System" in his head.
In World B, he's the amnesiac richest man in Gotham, having lost his memory in a car accident. With his family watching him with complicated expressions, he has a "Dating System" and plays around in the world.
Bruce: I don't think this is right.
System: I think it's correct.
Bruce never gives up on uncovering the truth, but the truth can often weigh even more heavily than reality.
When he digs up old friends and children from another world beneath the ice of the apocalypse, the soul of the Bat, spanning hundreds of years, finally opens its eyes once more.
This time, everyone will get a perfect ending.
