The Kimura Twins are characters, one of Katana School's students and Naginata's loyal followers (henchmen) and one of the antagonists from the animated series, Shuriken School.
They are both two 10-year-old ninja students of Katana and are followers of Naginata.
Describing their personalities, they are sneaky and mysterious and will usually gather information for Naginata.
Chauvinistic and conflicted, they act superior and tough when they are together (both have a very co-dependent relationship) but when apart, they weaken. They are also dependent on each other. They are sexists as well, which makes them hate Okuni the most.
They're both slender with fair skin and black spiky hair, and also, they both wear black and salmon-red ninja suits.
