Sensei Wu was stressed.

He had finally gotten the four ninja to unite, the four now training under his supervision and meticulous training.

One problem.

An ancient, lost scroll has recently been uncovered, revealing that there was supposed to be five original ninjas, not including the green ninja, instead of four.

Sadly, the scroll was damaged due to time. The powers of this forgotten ninja, as well as their possible location, even the color of their gi (ninja uniform) all remain unknown.

He had searched all the big cities, all the big towns, now resorting to the small villages in the middle of nowhere. Currently, Sensei Wu walks through a small village, deep in the country side surrounded by rice-fields, keeping an eye out and hoping to find anything that could indicate the location of this mysterious ninja.
