Shinobi Kid III: The ShadowkickA wicked version of an oversplit ^_^;;
In his clan ninjas grow their hair long and bleach it as a sign of their promotion to the rank of assassins (from simple spies). They also start learning how to fight and use ninja weapons.
Promotion is usually done at the age of around 17-18 when the kid is no longer tiny enough to be a good spy. Here Kage is 18 and still kicking ^^ (in the most unpredictable directions)
