Prologue

Screams echoed through the hospital hallways. "AH!" In one of the rooms, laid a young women with a man, most likely her husband, and a young child around the age of two.

"Come on, Nana! You can do it! Just breathe!" The adult man encouraged the young women, Nana, who was giving birth to their second child. "What do you think I've been doing?!" Nana shouted in pain, gripping the male's hand tighter, turning the skin a deep purple color. The child, not used to hearing his mom yell, jumped and ran to hide behind his father's legs.

Just one more-"The Doctor cut himself off. "What? What's happening?" The male turned to look at the Doctor. The Doctor was silent, in fact, the entire room was silent besides Nana's heavy breathing. "W-Where's m-my baby?" Nana stammered, exhausted. The Doctor stood up straight, gloves covered in blood, holding a silent bundle of flesh. Dread filled the two parents at the silence coming from the baby and the Doctor.

Nana immediately started crying, already knowing the answer. The male turned away and looked down at his oldest, only to see him blinking up at him with confusion in his doe-like eyes. The man opened his mouth, but a deep voice interrupted him. "Iemitsu….correct?"

The pair immediately looked where the voice came from, only to see a man with blonde hair and glowing orange eyes standing by the Doctor, looking at the silent infant. "You….." Iemitsu was shocked. 'Why is the Primo here? Or more importantly, how?' Iemitsu thought to himself. The man, known as Primo, just gave a small smile at the pair before raising his hands towards the baby still in the Doctor's arms. Flames appeared from Primo's gloves and he hovered them over the baby.

Crying soon rang throughout the room, bringing relief to the occupants. The Doctor began laughing in joy as he washed the baby and wrapped it in a pink bundle, "Congratulations, Mrs. Sawada it's a healthy baby girl!" The Doctor handed Nana the pink bundle, as the family gathered around; Iemitsu placing Tsuna onto the bed so he could see his new sibling. "She's beautiful!" Nana cooed, calming down the new addition to their family. The baby girl had a tuff of blonde hair, inherited from their father, but both parents were shocked when they saw her eyes. The shape was slightly narrow, but the color was a semi-dark orange with a very dark orange shade in the very center, surrounding the practically non-existent pupil.

'These are the Primo's eyes….did he possibly pass his flame onto her?' Iemitsu questioned. "Eh? Where did this necklace come from?" His wife's question brought him out of his head and stared at his youngest. There around her, was a beautiful pendent charm locket, and inside of the see-through and detailed locket was a bright orange light. 'That must be Primo's flame….' Thought Iemitsu. 'Why would Primo do all of this just to bring his child to life?' Was the big question running through his head. Not that Iemitsu wasn't grateful, opposite in fact, he was very grateful for what Primo had done for his family. He was just curious on how and why his family caught the attention and made Primo himself appear before them.

"What should her name be?" Nana asked her two boys. "N-N-Natsu…..suki." The two looked at their oldest, and smiled to see that the young boy was looking at his little sibling with awe. "Natsuki? That's perfect! Our little Natsuki." Nana cooed as she brought the newly named Natsuki to rub her cheek against hers.

Iemitsu smiled at the scene as he sat down beside his wife and brought their oldest closer together for a family huddle. Iemitsu could tell that Nana was going to be overprotective and cautious with Natsuki, so he'll only hope nothing bad happens in the future.

Meanwhile

"Oi Primo! Do you really think it was a good idea to give the brat a part of your flames?" A calm and deep voice called out to the blond as he returned. Primo glanced at the man, then gave a smile. "She's the one who's going to bring everyone together again, including them." He stated. "Really? Well, guess I can't complain. The brat has her work cut out for her." Primo chuckled. "I'll be with her every step of the way, G." "Hey Primo?" "Yes, G?" "Isn't that brat technically yours since she has the exact same flame and looks as you, not to mention the probability of the same personality as you in the future?" It was silent. "Oh…..I didn't think of that." "Idiot!" "OW!"
