From the introduction:
The ninja train for elite operations in Danketsu under the stern tutelage of Master Daiku. They are not necessarily young ninja, nor new to their positions, but Master Daiku holds a singular reputation - and ever ninja hopes to earn his approval, as he holds their future with the Lotus Coalition in his hand. If they can prove themselves, they'll earn the right to lead dangerous missions and take apprentices of their own. There is but one test left, a dangerous one that none of the elder ninjas wish to speak of, and they can all feel it is coming soon.
