Bee

The Ninhachi, ( Literal meaning 'Ninja Bees',) are a species of Bees; these 'ninja insects' are bred and utilized exclusively by the Kamizuru clan as the focal point of their unique techniques. The Ninhachi have only appeared in the anime-only 'Bikochu Beetle Hunt' filler arc in Part I of the anime. In combat, the Bees are recognized as a kind of Ninja Tool, similar to the use of the Kikaichū used by the Aburame clan, the sworn enemies of the Kamizuru clan.

Unlike the Kikaichū, the Ninja Bees do not seem to able to drain Chakra, but rather their offensive capabilities centre around their stings, with attacks like the Thousand Bee Stings Technique. The relationship between the Ninja Bees and the Kamizuru Bee-user clan seem to mirror the symbiotic relationship of the Aburame clan with the Kikaichū Ninja Beetles, where-in the clan members allow the insects to nest within their bodies in exchange for their obedience and their services, but in the Bee-user's case, they seem to summon more bees, rather then house them within their own bodies.

Demonstrated in the 'Bikochu Beetle Hunt' filler arc, the Ninhachi seem to be easily used frivolously in tactics where the bees lives are sacrificed without concern for their survival; techniques like Jibachi Kamizuru's Bee Bomb Technique shows the bees being sent to attack with Exploding tags attached to them.

The Kamizuru clan seem to use their insects for tactics more like the Spider-user nin, Kidomaru of the Sound Four, then the Aburame bug-user clan. They instead summon their respective insects, they'll even summon queens/egg-laying females, like Kidomaru's summons, Kyodaigumo, to spawn hoards of bugs to engulf their opponants and helpless victims to obtain their victory.

The Ninhachi, unlike the Kikaichū, seem to be able to grow to a large size, as seen when Suzumebachi Kamizuru summoned her personal summons, a Giant Bee, to attack Shino Aburame, Kiba Inuzuka, Hinata Hyuga, and Naruto Uzumaki during her clansmen's mission to obtain a Bikochu Beetle uncover a scroll left over from their grandfather, the First Tsuchikage.
