One Piece? No! It's the Powerhouse Dad Piece!

Five-year-old Aier transmigrated. A voice in her head said it could help her find her family, and the orphan agreed.

[Beep~ Welcome, Host Daddy, to the "Pin Dad Together" System! You win by competing!]

Aier: Huh? Is Dad the one being bound to it?

The first person Aier sought out was a handsome young man with black hair and freckles. She had blonde hair, but they did have one thing in common: they both had freckles.

So this must be my dad!

Ace had assumed the little girl had mistaken him for someone else. He never expected she really was his daughter!

He brought her back to the ship, where the members of the Whitebeard Pirates crowded around to tease her. "Where'd this little girl come from?"

Ace scratched his head. "Uh... she's my daughter."

Everyone: Huh?!!! What do we do now that our new crewmate has a kid?!!

When they tried to eat and run, [Beep~ Triggered a ten-billion subsidy!]

Ace enjoyed a free, delicious meal, then ran off with Aier.

Meanwhile, Whitebeard sat on the ship, staring silently at the empty stash he'd been saving to buy booze.

One day, Aier transmigrated to the wrong timeline and found her second dad. This time, the man had the same hair color as her. He was a little clumsy, but he treated her well.

He worked nine to five and brought home tasty treats for her every day! She also had a kind old marshal grandpa to play with!

But one day, he disappeared. Grandpa said he'd gone on a mission.

Missing her dad, Aier secretly set out and eventually found him after a long journey.

But why were there two dads?

Doflamingo never expected his younger brother, whom he hadn't seen in years, to return with a child. Pointing at Aier, who couldn't tell the two men apart, he asked, "Is this your kid?"

Rosinante nodded hesitantly.

On Minion Island, [Beep~ Triggered: One more hit to defeat!]

Doflamingo, after firing several shots and realizing Rosinante was still alive: ?

The other dads are yet to be decided...
