Can Ultramen Have Romantic Troubles Too?

It took only a few thousand years for Zero to go from an underage juvenile delinquent to a great hero of the Land of Light, and he still wasn't an adult.

Then he got a human host who had a daughter, and suddenly Zero thought, I want a daughter to grow up alongside, too.

Zero was lucky enough to find a little female Ultra. Despite Seven's objections, he adopted her as his daughter.

Infinity was a happy little Ultra. Her father was a famous hero of the Land of Light, and she was lively and cheerful. Every Ultra loved Infinity.

From a young age, she was determined to become an outstanding Ultra Warrior.

After growing up and becoming an outstanding Ultra Warrior, she developed a new problem: what should she do if she fell in love with her adoptive father?

She had never experienced Zero's youthful, brash adolescence. The Zero she knew was mature and steady, yet still full of spirit.

Zero turned her down and brushed a finger across her forehead. In a daze, she thought she saw her father crying, but when she came to, she realized it was only an illusion.

He said, "I'm sorry. I'm just a father."

Infinity was heartbroken. She didn't want to lose her father, but she didn't want to lose a partner named Zero either. So she made a daring decision.

She would travel to a parallel universe and date a young Zero.

Zero was training at the juvenile detention center. Leo had just kicked him unconscious. The next moment, a beautiful female Ultra shook him awake. She jumped to her feet, full of excitement, and announced that she was his girlfriend.

Zero: Are you kidding me? There's no way this young master would...

But when he met Infinity's teary-eyed expression, he swallowed the rest of his words.

Later, Zero realized that Infinity always stood by his side, firmly believing that he could beat Leo and get out. She even said that he was a great hero of the Land of Light.

What nonsense. Someone like him had committed a terrible crime...

Zero started training even harder. At the very least, he wanted to become the hero she believed him to be.

Later, Zero fell in love with K76, because they gave out wives for free.

He really did become a great hero of the Land of Light, and his relationship with Infinity was finally acknowledged after her father suddenly showed up.

Infinity's father had come to find her. Zero stared at the face that looked exactly like his own, only older, and was too shocked to speak.

Zero never expected that he'd have to call his parallel-universe self "Dad."

The other Zero never expected Infinity to be so reckless, or that she'd actually find a younger version of him as a partner. But there was no way he would agree to it.

He picked Infinity up without hesitation, sat her on his lap, and spanked her. Then he left with a flourish, telling the other Zero, "You're two hundred thousand years too young to steal my daughter."

Infinity was stubborn by nature. She declared that she was going to date Zero, and also find countless other Zeros to be her partners.

(I've already thought of the bonus chapter for this story: she travels back to when Zero is still a little ball of light and falls for Seven.)

I'm so wicked after all (sobs).
