Vongola Decimo, aka. Tsunayoshi Sawada, was doing his paperwork caused by his beloved guardians. He felt frustrated because of the number of paperwork he has to do. Then someone knocked on the door.

"Come in," the brunette said without paying any attention to the person. The man with silver hair and green eyes, wearing a regular mafia suit came in.

"Juudaime, the three mechanics maniacs want to see us in their laboratory." The man informed calmly despite his words of description.

"Alright, thanks for informing me, Hayato." Tsuna replied as he smiled at his right-hand man and his storm guardian, Hayato Gokudera.

"It's my duty, juudaime." Hayato bowed and then walked out. Tsuna followed suit. When they got there, they noticed that all the guardians had gathered.

"Ah! Juudaime, I'm glad you're here!" Giannini exclaimed happily.

"Tsunayoshi-kun, we invented a new machine that can improve the box animals' capabilities in combat. We haven't tried it yet so we don't know if it will work or not." The red haired man, Shoichi Irie, smiled sheepishly.

"What the hell do you mean?! What if it damages our box weapons?!" Hayato yelled angrily, not liking the idea of risking his box weapon. (For those who thought that Gokudera isn't quick tempered now after 10 years, you're wrong. I like the raging storm more than the calm storm. If I make Gokudera to be composed, there won't be any fun writing about him now will there?)

"Maa, maa...Hayato, calm down. I'm sure if something goes wrong, they could fix it." Vongola Rain Guardian, Takeshi Yamamoto, smiled as he tried to stop the storm.

"We would have to try to know what will happen," The monotonous voice spoke up. The blond head, Spanner, looked up in bored expression as he ate his lollipop. "So summon your respective box animals and put them in front of the machine." They did what they was told. Tsuna brought out his Sky Lion, Natsu. Hayato brought out his Storm Cat, Uri. Takeshi brought out his Rain Swallow, Kojiro and Rain Dog, Jiro. Lambo brought out his Lightning Bull, Beef Bowl. Ryohei brought out his Sun Kangaroo, Kangaroo. Mukuro brought out his Mist Owl, Mukurowl. Kyoya brought out his Cloud Hedgehog, Roll.

After they put the animals in front of the machine, the animals start to glow and a bright light flashed before them. When the light died down, the group was shocked. Before them were...
