A duo of brother ninjas have taken over the city. Many have tried to capture them but have miserably failed. In preparation for world ninja domination, the brothers set up ninja camp to practice their swordsmanship and ninchuckisms. To guide themselves in the darkness, these night ninjas illuminate as they accumulate strength. It won't be long until the world is ninja stricken by fellow ninja brothers and sisters.
Each pocket ninja comes equipped with a weapon. When a user squeezes the stomach of the sword pocket ninja his eyes light up. The ninchuck ninja must block his hit by putting his hands together. If he does not block in time, the ninchuck ninja is hit and releases a cry of pain. In return, the ninchuck ninja can attack his brother when a user squeezes his stomach to build up enough strength for some serious ninchucking. The sword ninja can also block the hit by putting his hands together or else he whimpers like a baby if he's hit.
