The Ninja, whose specialty is swift movement, is a hybrid class that uses not only ordinary weapons but also throwing weapons and ninjutsu, allowing it to perform both physical and magical attacks alongside a variety of evasion skills.

Ninjas can defeat enemies using daggers, Wind and Demon Shurikens, throwing knife-type weapons, and "ninjutsu" which resembles magic.
