Yes, it has ninjas.
From the campaign:
In Shuriken, players take control of 250 plastic ninja including unarmed, sword, shuriken, and master ninja. During the game the players place, move, and upgrade their ninja forces on the modular board as they attempt to learn new techniques and battle enemy ninja -- often destroying the board in the process.
The winner is the player with the most victory points when the sun rises at the end of the night.
