A 4 year old brunette  was sitting in his room. He was using an old computer the boys name is Sawada Tsunayoshi  or Tsuna for short for short he is in the middle of hacking into the security files of the famous  mafia famiglia, the Vongola famiglia.

The boy leans back in his chair, smirking reading all the information that appears on the computer screen.

"I  see.... that's interesting who would have thought that father who claims to work construction but really  he is the CEDEF  Boss of the Vongola... very....amusing"

This causes a young boy to start his adventure in the world of hacking. Tsuna  is very very intelligent for his age. He loves to learn and absorb  things he sees. He is very calculate things mentally in seconds, decipher codes and solves them in an instant with in seconds he lays on them. All in all, he is a young genius. He even is learning foreign languages. Though he is a genius, he refuses to tell anyone  of his abilities he hides behind a facade of a dame child he does this for safty of his family  he knows if people knew people would seek him out for his abilities and  will even go as far as endangering his family to have him. Tsuna  copies all the information he collected after he copied all the  files he erases an trail of him so they couldn't track him back. He shuts the computer.
