Karlheinz was never a good man. Everyone knew it. He was terrible. Most of his children hated him, even those who weren't his own. Despite this, he only kept one child around, and that was you.

The only daughter Karlheinz had.

He couldn't dream of anything better. But it's not like he was keeping you around to love you. No, he didn't love you. He never loved you. Not the way a father loves a daughter. He was mean, rude, and beat you. He said everything was to make you stronger, to surpass him. But you never wanted to surpass his strength; you just wanted to be loved.

"You're a disappointment. You'll never surpass Ayato like that," Karlheinz spat, right in your face.

You stood in front of him, your face cut, one eye half-blind, and the muscles in your body aching. He made you train for exactly 24 hours, nonstop. Your fingers were calloused and aching, red. He could even see blisters there.
