"Robin, let me introduce you to Monet. From today, you two are sisters, so get along, okay?"
"Umu!! Okay, Dad. Come on, Monet, let me introduce you to Ai and the others!"
Robin quickly grabbed Monet's hand and led her to meet the other inhabitants of Laputa.
Monet, still not understanding what was happening, could only follow Robin's enthusiastic lead.
Meanwhile, Sora began to explain what had happened and how he had come to bring Monet with him.
-----
On a snowy island in the New World, Sora, detecting the presence of a devil fruit, casually explored the island.
However, when Sora used his Kenbunshoku Haki, he was surprised to sense a human presence on the island, especially since the aura belonged to a child.
Wasting no time, Sora quickly teleported near the dying child.
Upon arrival, although Sora was accustomed to death, the sight before him was deeply moving.
He saw the corpses of a man and a woman, smiling in death, but their legs were reduced to bones, and the blood around them had frozen.
There was also a small girl, perhaps the same age as Robin, with dirty green hair, flat orange eyes, and a face and mouth smeared with blood.
Just by looking, Sora knew that the adults were the girl's parents, who had sacrificed their bodies as food and energy for the child.
Sora quickly gave the girl a potion to heal her injuries.
After ensuring that the girl had only fainted from stress, exhaustion, and hunger, Sora decided to preserve the couple's bodies to bury them later.
He crafted various tools and turned the cave into a safe and comfortable hideout.
Some time later, Sora felt the girl starting to wake up.
"Calm down, child. You're safe now. I saved you, and I've kept your parents' bodies to bury later. Now, can you tell me your name?"
The girl, initially scared, gradually calmed down, realizing she was safe, and observed Sora closely.
With a flat tone, she replied,
"Monet, my name is Monet."
Hearing the name, Sora was slightly shocked as it was the name of one of Doflamingo's top officers, Monet the Snow Woman, whose body was modified to resemble a harpy and who possessed the logia-type devil fruit Yuki-Yuki no Mi. Monet was a formidable opponent for the Straw Hat crew.
If this girl was indeed that Monet, it likely meant the devil fruit on the island was the Yuki-Yuki no Mi.
Sora was delighted at this possibility, as he could gain a loyal follower and a devil fruit perfectly suited to its user.
Without further ado, Sora offered Monet to come and live with him, also mentioning that he had a daughter named Robin, the same age as her.
Hearing the offer, Monet, unsure where to go if left alone, chose the best option before her: to go with Sora.
After ensuring Monet's body had fully recovered, he took her to search for the devil fruit on the island.
Sure enough, it didn't take long to find the fruit, which had pure white scales that would have been hard to spot in the snow if not for its green stem.
Sora took the fruit, feeling the cold emanating from it.
Handing it to Monet, he said,
"Here, Monet-chan, take this. You can become stronger with this fruit, and you won't have to fear losing family members again if you're strong."
Sora's words ignited a surge of emotions in Monet's heart and soul.
"If I'm strong, I won't have to lose my family again... Alright, thank you, Sora-sama."
Monet accepted the devil fruit from Sora's hand and ate the whole fruit. Despite its terrible taste, Monet held back her tears, which flowed perhaps from the disgust of the fruit, the sadness of remembering her parents, or the joy of a new possible future.
Initially wanting to stop Monet, Sora decided against it when he saw that she had regained her will to live.
Thus, Sora decided to stay on the snowy island for a while to teach Monet about her new powers, as the island was a perfect place for her to learn.
-----
Hearing Monet's dark story, Sora's wives felt sad and decided to care for Monet together as they would their own daughter, letting her decide what she wanted to become in the future.
Although some of Sora's more perverse wives suspected that Monet would eventually become one of them, as Sora's future wife.
Sora decided not to travel again until the time for the assault and destruction of Ohara, about two years later.
Of course, having been away for a long time, Sora spent time together and satisfied the sexual desires of all his wives, letting the world turn and correct the mistakes caused by Sora's interventions.
