I-Ninja is an action video game developed by Argonaut Games and published by Namco. It was released for the Microsoft Windows, PlayStation 2, Xbox and GameCube (in Europe, the game was available only for the PlayStation 2 and Microsoft Windows). A Game Boy Advance version of the game was announced, then later cancelled. Plot The game starts with the protagonist, a hot-blooded yet very rude Ninja in training (simply named Ninja), who comes to rescue his Sensei (simply named Sensei) from the Ranx sent by Ninja's nemesis, Emperor O-Dor. Ninja saves Sensei by defeating the Ranx. Then, a creature comes to attack Ninja which he deals with easily. The creature then spits out a Rage Stone which Ninja touches and goes into a fit of rage and accidentally kills Sensei. Sensei comes back as a ghost and tells Ninja that there are more Rage Stones and with their power, he can defeat O-Dor. Sensei then sends Ninja to find the second Rage Stone in Robot Beach.
