Hiro is the youngest of all the Mini Ninjas. He was found as an infant by the Ninja Master and has grown to be one of the most promising ninjas in hundreds of years.
His talents with Kuji magic are only matched by the Evil Samurai Warlord, and with time he could become the greatest Ninja of all. Now Hiro must go on his greatest quest to restore balance and harmony to nature.
Futo is not the fastest ninja in the village. During his training, it became obvious that Futo was never going to be particularly skilful with the sword but his raw strength was perfect for the hammer. His great heart should also not be underestimated.
Suzume is the master of the flute, and perhaps one of the most agile and swift of all the ninjas in the tribe. She is sweet and innocent on the outside, but if angered, capable of delivering a fearsome frenzy of attacks. Above all else, Suzume prides herself on being stealthy and only using force when absolutely necessary.
Tora thinks he is a tiger. Ever since he was a small child, left on the steps of the ninja village, he has been infatuated with being one. This particular trait in Tora annoys the Tengu, and his trainers have gone to some lengths to weed it out of him, with little success.
Kunoichi is the younger and less mature of the girls. She looks up to Suzume like a big sister and adores Hiro. She is very acrobatic and uses her Naginata (spear) as a prop in her agile moves.
Shun is a living contradiction. He's the most tense of all the Mini Ninjas but oddly, he still maintains the unique ninja skill of calming himself to utter silence when the situation requires it. Shun is the stealthiest of all the Mini Ninjas.
Hiro and the other Mini Ninjas get to confront a wide range of enemies on their quest.
Animals have been transformed into samurai and have taken a variety of shapes from archers to regular samurai and captains to bosses and other creatures.
