Molly entered a game where the victory condition was to kill the tyrant. Her special ability was all about equivalent exchange: to get the ability she wanted, she had to trade away a bodily function.
On her way to assassinate the tyrant, Molly kept trading away abilities and changing builds without batting an eye, having a blast in battle as she died and came back to life every day. But the NPCs she rescued along the way were suffering terribly: Because you saved me, you ended up like this...
A wheelchair-bound war god who couldn't walk but could teleport; a frail blind monk who couldn't see but could summon flash grenades that blinded everyone; Molly, unable to speak but able to make hand signs faster than anyone: Huh? What?
It's not a tragic tale of a beautiful, powerful woman suffering. It's just how the normal game mechanics work!
But nobody believes her. It's hilarious.
In short, in a world full of misunderstandings, the tyrant's attitude toward Molly stayed consistent no matter what state she was in: he looked down on her with contempt and traded blows with her. It was oddly reassuring.
That is, until Molly saved a city on the verge of destruction.
In full view of everyone, she used the tyrant's ability... Wait, only members of the royal bloodline can use that ability.
Could she be the tyrant's daughter?!
With only a sliver of health left, Molly shakily reached out. "There must be some misunderstanding here. Let me switch to another ability..."
Before she could finish, she died.
Watching her breathe her last in his arms, the tyrant said, "..."
The child he'd just gotten, whom he hadn't even had time to warm up in his arms, had gone cold.
And so the whole world discovered that the tyrant had gone even more insane.
Orbital weapons took aim at countless cities, ready to fire. His vicious, icy voice rang out over the communication channels:
"Hand over my daughter, or you and the world will be destroyed together."
The tyrant Caesar had murdered his father and killed his mother, personally wiping out his entire bloodline. With peerless brutality, he destroyed everything that defied him, building his rule on devastation and countless crimes. The world was fated to meet its end at his hands.
That course of events came to a halt when his daughter arrived.
A tiny child, covered in scars, stopped breathing in his arms countless times. The man slowly lowered his head until his forehead touched his child's.
No matter what name you have, no matter what you look like...
"I will always find you. I will always come to your side. I will always fight for the world you hope for."
You are my only reason to keep going.
"Extra Scene"
Caesar: Hand over my daughter, or you and the world will be destroyed together.
Desperate bystanders who don't know the truth: @Princess Who Might Not Even Exist And Whose Name, Looks, Height, And Weight We Don't Know Please Come Save The World And Take Your Dad Away QAQ!!!
Molly, back at the respawn point: The most urgent thing now is to download an anti-scam app for special abilities for him.
Some time later...
Happy bystanders who now know the truth: @Great Princess, Will You Ascend The Throne Today? If Not Today, Then Tomorrow, And If Not Tomorrow...
Meanwhile, in the imperial palace
Molly: Seriously, man, I really don't want to be a princess. Can you just send me back to Earth?
Caesar: Call me Father, and I'll give you the whole planet.
Molly: Are you crazy? What would I even do with that?
Molly, a heartless girl with a peculiar way of thinking, and her daughter-obsessed father, a tyrant who is all-powerful, wildly arrogant, and dazzlingly cool in the early stages, then completely loses it and goes berserk later on.
The protagonist has a love interest. The tyrant does not.
This is not a conventional child-rearing story. The protagonist has an independent personality and can take care of herself. Many secret identities die throughout the story.
