Birthday: 23 July
Zodiac: Cancer
Rank: Genin
From: Leaf
Teacher: Kakashi

Background: Sole survivor of the Uchiha clan when his elder brother went on a killing rampage.

The Deal with him: Sasuke was a regular adorable ninja student with big dreams of being an excellent ninja like his elder brother. But after Itachi killed their family and screwed up his mind to "live in an unsightly way", Sasuke became cool, and calls himself an 'avenger', whose purpose in life was to kill his brother. For some obscure reason, that made all the girls at the academy fall in love with him.
