I would like to make some clarifications before starting on the chapter.

Firstly, the Vongola I am using in my story is five years after where the anime stops and although I am only using knowledge up to the anime. (Which means that the Vongola gears are not used and the family is using the Vongola true form rings.)

Also, instead of the animal rings which were shown at the end of the anime, I have decided to carry on with the use of boxes instead of those animal rings.

In addition, the pokemon I am using is from the manga named "Pokemon Adventures" and I am only using up to where the Emerald arc ended. (Which means no pokemon after the Hoenn region would appear.)

Sorry if this disappoints any readers who are looking forward to those gears and pokemons but the reason I only write to this point is because I lack knowledge on those pokemon and gears. :(

Still, I hope that you all would enjoy the story! :)

Disclaimer: I do not own Katekyo Hitman Reborn or Pokemon.

"Ack! The pokeball bounced off it again..." A young boy, around the age of ten, said with much disappointment in his voice as he watched the sight re-enact before him once more.

A girl who looked around the same age, stared at the boy and asked him doubtfully, "Are you sure you can catch that Nidorina? You've failed to do so the last time." She giggled slightly as she mocked at her friend.

The boy immediately placed his hands on his waist and grabbed another empty pokeball from his belt while shouting loudly, "I'm gonna capture this Nidorina and train it all by myself!" After saying that, the boy took an aim at the wild Nidorina and gave another shot, hoping that he would succeed at this try.

Bounce! "Oh no! I failed again!" the boy grumbled at his failed attempt of capturing the wild pokemon, feeling slightly discouraged.

Just then, two tall teenagers stood beside the boy and the one wearing a red cap with a red rectangular box on his waist spoke, "Hahaha, of course you failed. You must battle it first." The teenager then pointed to the boy's waist and commented, "Oh, that's a strong-looking Gengar you have there! Why don't you use it?"

Heeding his advice, he sent out his Gengar to battle against the wild pokemon while the teenager watched on excitedly. At this moment, the other teenager with brown spiky hair and had the same red rectangular box who had accompanied the other felt annoyed at the childish nature of his friend. Unable to control it in, he burst out at him.

"Get over with it will you Red?"

"Hahaha, sorry Blue. I know we are sort of rushing for time but I couldn't help watching these kids..." the teenager called Red apologized to his friend.

"Eh, aren't you both the Indigo Plateau Champion and runner-up respectively?" the girl exclaimed in surprise.

"Yup, that's us!" Red told the girl as he was walking in the direction of where his friend had already left. "Hope we meet again!" the red-capped teenager waved back at the kids and ran off to catch up with his friend.

"Just a few more minutes and we will arrive at the island." Gokudera told the team. They had been riding on the air bikes for hours and were starting to get exhausted from the long journey.

"Is everybody feeling alright?" Tsuna asked his family members with much concern.

"Hai Jyuudaime!" Gokudera answered the boss at once with as loud as he could to try and show the boss he was not tired. However, Tsuna still knew that his right-hand man was actually very tired due to the fact he had hyper intuition.

Yamamoto gave a wide smile with a thumbs up at Tsuna as he said, "Not a problem here!"

"I'm extremely doing great here. But it doesn't seem the case for this kid beside me." Ryohei told the boss, then looked beside him. There laid the cow-shirt boy sleeping soundly in the carriage that was form after Ryohei and Lambo combined their air bikes. "He seems to be extremely tired from this journey."

The brunette looked at the sleeping boy concernedly and muttered, "Lambo..." while he thought to himself whether it was a right choice to bring Lambo along to this mysterious unknown island. Moreover, even though Lambo is his guardian and has been through numerous dangerous battles with him, he is only ten this year...

"Tsuna! Look out!"

ROAR!

"Turn your air bike Tsuna!" the infant shouted at once. The brunette immediately listen to the infant's command and made a 90 degree sharp turn and drove off to the other direction from the monster, narrowly avoiding it's monstrous bite.

"Are you alright Jyuudaime?" Gokudera shouted in concern of his boss and heaved a sigh of relieve when his boss nodded his head. "This looks like the mythological chinese dragon. Why did it appear here?" Gokudera muttered as he thought to himself.

"We are just so close to the island... Onii-san, can you bring Lambo to the island and protect him there? I can't risk him getting injured here." Tsuna told Ryohei who in turn nodded and drove at his fastest speed towards the island while trying to avoid the water creature. "Reborn, Yamamoto-kun, Gokudera-kun, let's prepare for battle."

"Open box!"

"Let's go Jirou and Kojirou!" Yamamoto shouted as he opened his Vongola box, letting the rain-attributed dog and swallow out, and wielded his sword which was transformed from the wooden stick at his back.

"Sistema C.A.I!" Gokudera shouted as he too opened his Vongola box with his storm-attributed cat, Uri, coming out of it.

"Leon!" Reborn shouted as the chameleon transformed into a green pistol.

"Natsu!" Tsuna shouted as he opened his box and summoned his sky- attributed lion out for battle. "Let the fight begin!" With that said, the four charged towards the sea creature.

Knock Knock.

"Professor Oak! Are you in? It's us, Red and Blue!" Red shouted loudly as he knock the door of the research laboratory.

The door opened and there stood a gray-haired man with a white coat. "Ah it's the both of you, come on in." As the man lead the two teenagers into his laboratory.

"Why did you suddenly called the both of us back so urgently grandpa? Is something wrong?" Blue asked the professor who had a grave look on his face.

Professor Oak gave a sigh and looked at the two for a few moments before telling them, "Something very serious has happened and I think that only the two of you are capable of stopping it..." Professor Oak hesitated for a while before continuing, "Team Rocket has once again been sighted in Kanto."
