The Uchiha heir grew with all the commodities since he was born, being taught from the very beginning how to fight, defend, deceive and kill.

For those stranger to mafia, or civilians, Uchiha clan owns multinational companies of art and preservation of old pieces of story, like totems, talismans, amongst others. It gives the clan credit for helping humanity keep its roots high and be proud of them, although one doesn't get that much money only with ancient stuff....

Naruto Uzumaki was a very poor boy, who grew raised by an oldman he called "grandfather". Since he was young, he fought for everything he had, but as he grew and his grandpa went sick, he was forced to enter the dark word to provide for that poor old man that had raised him even without having to...

Naruto had always been kind hearted, but the conditions made him learn how to defend himself and steal, since he and his grandfather lived in a very dangerous neighborhood, he had to adapt to survive, and inside the neighbor, he gained the popularity of one of the best fighters and the best at getting whatever a good bidder asked him to. Like that, the Uchihas heard about him and hired him to be one of their assassins. When he was gotten under intense training, he proved himself better than most, even if he didn't really want to be there, he had to, and dreamed of a better future for himself and his grandfather...

Being good led him to meet even the higher ranked Uchihas, including Fugaku Uchiha, Sasuke's father and the head of the Uchiha mafia, quickly ascending into being the old leader's right hand worker. And like that, one day he was assigned to a mission with Sasuke himself.

The Uchiha was very reluctant to do a joint mission, he was a loner and hated having to depend on other people, but orders were orders, even more so if they were from his father. The mission wasn't an easy one at that, they had to steal something from another important Mafia head, the Hyuugas, and their objective was a very rare collar in the shape of a flame lion.

As they were given the equipment and Izumi Uchiha, one of the logistic heads, explained how would they proceed, Sasuke wore his bullet proof jacket before casting a glance to the blond who was getting ready as well. He kept sitting on the couch a few feet away from Naruto and spoke to him. Sasuke: coldly you better not hold me back, newbie.
