I was just thinking about this. Why is it that there are only a few people who have brother's? (Tell me if i miss some) Garra has one brother and a sister. Sauske has itachi. 2 shinobi brother's (don't know their names) eaten by the 9 tails (Kurama). and 3 shinobi brother's (who are weak) that want to kill kakashi because he rescued a girl from them. sai and his brother. Is it to limit the # of characters they use? My point is why didn't they give like sakura a sister or anyone else? i dont mean if they had brothers or sister and are now dead.
