Chapter 1: A Child's Resolve

A five year old Harry watched horrified as his best friend's mother was murdered right in front of them. Blood splattered the two five year-olds. They shivered as the man ran off after Takeshi's father came running in the room with a sword in his hands.

"Are you alright, Harri, Takeshi?" Tsuyoshi Yamamoto, Takeshi's father asked his son & his son's best friend. "Yyeah, tou-san." Takeshi stuttered so badly Tsuyoshi could barely understand his son. Harry didn't respond so he turn to the younger boy.

THUD

Takeshi screamed as he shot up in bed. Tsuyoshi ran into the room seeing his seven year-old son crying as he gripped his sheets in his fists. "It's alright, Takeshi, it was just a nightmare, it wasn't real." He comforted his sobbing son, as he hugged him.

The day had changed the boys from happy go lucky to cold and distant. It saddened Tsuyoshi to see his son and his best friend suffer so much from that dreadful day. He trained both boys with a sword in hope they would never suffer the same fate as his wife.

The boys were genius' with blades, but Harry preferred daggers over a katana. The two seven year-olds sighed as they walked through the streets looking for the place their target was at.

Heroshi Yanuki was their target. The two were assigned to kill him by their client; Jinko. The red-headed man was eating a bowl of ramen when a dagger pierced through his skull and killed him.

His face landed in the ramen, causing people to scream in panic. A blonde two year-old watch them and smirked. He followed them quietly as they made their way back to Takeshi's house.

Colonnello smirked as he watches his student's train. "Again, kora." He called out to the two seven year-olds. They had been training under him for six months. Harry groaned loudly as he struggled to stand. "Shimata!" Harry yelped as he rubbed his sore legs.

"I can't move, How am I supposed to do this when I can't stand?" Harry asked his mentor. "That's not my problem now is it, Kora?" Colonnello asked sounding sadistic as he did so, causing shivers to run down both Takeshi & Harry's spines.

"Now get back to you're training before I start shooting you two, you have two more weeks of training with me and you're not going to waste it lounging around, kora!" He shouted at them causing them to stand on shaky legs and get back to their training.

Harry stared at the picture of their target. "It's him, Keshi-kun." Harry whispered anger filling the seven year- olds body. "So he's the one that killed kaa-san?" Takeshi asked sounding angry. "Yep, and he's part of a mafia family known as the Gelios Famiglia." Harry said helpfully. "Anybody working with a man, whose so cruel he'd kill a five year old boys mother, deserves to die a painful death." Takeshi said in an icy tone of voice.

"So we will kill them all?" Harry sounded worried about something. "Don't worry so much, we can do it. I mean it can't be that hard to kill a bunch of cowards, right, Ha-kun?" Takeshi asked his best friend, who nodded his head unsure of himself.

Harry used a dagger to slice through a guys arm causing him to pass out from the blood loss. "HAVE MERCY? HAVE MERCY? DID YOU SHOW MY MOTHER MERCY WHEN YOU MURDERED HER IN COLD BLOOD! I WON'T SHOW YOU ANY MERCY WHEN YOU REFUSED TO SHOW MY KAA-SAN ANY. WHAT KIND OF PERSON MURDERS A WOMAN IN FRONT OF HER FIVE YEAR OLD SON AND HIS FRIEND! YOU DESERVE TO TO ROT IN HELL FOR WHAT YOU PUT ME THROUGH YOU BASTARD!" Takeshi Yamamoto screamed at the top of his lungs.

His voice was filled with hatred & malice. "I'll show you why they call me the Everlasting Rain, it's because all my victims have felt an endless despair, like it started raining and never stopped." He said in any voice filled with hatred which was directed at his kaa-san's murderer.

Takeshi used his Rain flames to kill the man that had pretty much ruined his childhood. "It's over, we need to leave before the Vindice arrive to arrest us." Harry said as he looked around the streets & inside the warehouse where the Gelios Famiglia had been in.

The streets were coated in a river of blood and flesh, as was the insides of the warehouse.

"You want to join the Vongola Famiglia?" The Ninth Boss of the Vongola Famiglia asked dumbfounded, but he hid well. Iemitsu Sawada seemed just as stunned as Timoteo was. Suddenly Timoteo started laughing happily. "You two will make fine Rain & Wind Guardians for young Tsunayoshi. Iemitsu give them the Rain & Wind Vongola Rings." Timoteo said firmly.

"Are you sure, they are only nine years old, they may not be ready for them, yet?" Iemitsu protested, until he saw the stern look on Timoteo's face. "They Personify what being the Wind & Rain guardians means. To become a blessed shower that settles conflict and washes everything away. To become the gentle breeze that buffers both storm & cloud and creates peace." Timoteo said calmly.

Iemitsu sighed but handed Timoteo his half of the Rain & Wind Vongola Rings. Timoteo connected it with his half and hand the two rings to their new bearer. Harry placed the Wind Vongola Ring on his right index finger. While Takeshi placed the Rain Vongola Ring on his left ring finger.

"Welcome to the Vongola Family, Harri-kun, Takeshi-kun. Harri-kun, you will one day take Iemitsu here's place as The External Adviser to the Vongola Famiglia & the Head of the CEDEF, do you understand me?" Timoteo asked the new member of the Vongola Famiglia.

"Ciaossu." A voice said causing Takeshi & Harry to look stunned at Reborn. "Why is there a baby here?" Harry asked annoyed at the hit-man in front of them. "I'm here to continue you're training. The Vongola Nono asked me to train you." Reborn said calmly, with a cute little smile on his lips.

"I am Reborn." The Arcobaleno said calmly, as Leon transformed into a gun, causing Takeshi to start laughing. "Hahaha! Look he's got a toy gun." Takeshi said laughing until a bullet nearly hits him in the forehead. The only reason he didn't get hit was that he had honed his reflexes to avoid even a bullet.
