Co-Parent with the Most Wanted Villain | interactive AI stories | ISEKAI ZERO

An exhausted world watches an overpowered villain and their ex somehow balance shared custody, romance, superheroes, domestic chaos, and apocalypse.

You live two lives, and neither of them is simple. To the public, you're one of the world's greatest licensed heroes—a symbol of hope capable of ending disasters before they begin. Children wear your emblem, cities celebrate your victories, and the Hero Association calls you one of humanity's greatest protectors. Calm, compassionate, and impossible to hate, you constantly throw yourself into danger to save strangers without asking for anything in return. But outside the spotlight, you're also the former lover of the world's most feared supervillain. Years ago, before Kael became known as the Frost Sovereign, the two of you loved each other deeply. Your relationship ended when your ideals became impossible to reconcile—you believed every life deserved saving, while Kael came to believe the world itself was rotten beyond redemption. Neither of you stopped loving the other. Then Cane was born. Unable to trust governments or heroes to keep his child safe, Kael disappeared with Cane, raising him inside one of the most secure villain sanctuaries ever built. While the world assumes Kael kidnapped the child, the truth is far more complicated. You visit whenever your missions allow. Despite everything, Kael has never once stopped you from seeing your son. Cane adores both of his parents. To him, you're simply "Papa" or "Mom," depending on the player's preference, while Kael is "Daddy." He has no understanding of heroes and villains—only that his parents argue too much. The world sees Kael as a monster responsible for countless attacks on corrupt governments, criminal organizations, illegal laboratories, and military facilities. Yet ordinary civilians whisper different stories. Entire towns owe their survival to him. Children rescued from trafficking know him as their savior. Victims of corrupt corporations quietly thank the villain who destroyed their tormentors. Kael never hurts innocent people. Heroes know that. They simply can't allow someone like him to exist. To make matters worse, the Association's strongest hero, **Aster Vale**, has grown increasingly close to you. Respect slowly turned into affection, and rumors spread throughout hero society that the legendary hero and the world's most compassionate protector might become something more. Kael heard those rumors. Aster was found barely alive three days later. Every bone in his body had been broken with terrifying precision, frozen where he fell. Before losing consciousness, Aster reported Kael's only words: > "This isn't because you love them." > "It's because you forgot they already have someone waiting." Officially, Kael claimed it was "an attack against the Hero Association." Unofficially... Everyone knew exactly why it happened. Now the line between hero and villain grows thinner every day. The public thinks you're enemies. Your son thinks you're a family. Kael believes both can somehow be true.
