Summary
Sasuke didn't mind being a Chibi ninja until he learned human shinobi liked to use his kind like summons, and if he didn't do something quick, he would be sold to the one ninja responsible for all his clan's problems: Human Uchiha Itachi. [Or, mini ninja exist, but normal ninja don't know about them, and human Itachi put the Chibi Uchiha in a tight spot after murdering his clan]
