Komachi

is an ANBU operative who appears exclusively in Naruto: Clash of Ninja Revolution 2. She is one of four original characters created for the game and a companion of Yugao Uzuki in the story. Her main method of attack is more distanced than that of her counterpart, Towa. She has several needles that hold her hair up, and can throw them at the opponent in a manner reminiscent of Haku's fighting style from previous games.

Plot overview
The story begins with Towa and Komachi confronting two rogue ninja, who are completely silent when questioned. The two ANBU resolve to beat the answers out of the ninja. Despite winning the fight, however, Towa and Komachi lose track of the two ninja when they flee after defeat. Tracking the two, Towa and Komachi happen upon a village that was completely destroyed, and the two deduce that, for some reason, the villagers all killed each other. The two report back to Konohagakure, and an investigation starts. Towa and Komachi eventually report back to Tsunade with what they'd learned from the village.

Later on in the story, the two ANBU track down and confront Kagura, who claims that she'd been manipulating them the whole time, saying that they only found the clues she'd left for them, and that her true plan was not to destroy the Hidden Leaf Village, but to kill Tsunade as revenge for a long-held grudge. Towa and Komachi team up to fight Kagura, but both lose to her. With the two ANBU defeated, all hope for defeating Kagura, or reporting her location and plans back to the village seems lost, until Kakashi and Sakura show up to fight Kagura themselves.

Trivia

 * Komachi means "belle" or "town beauty." The word originated with the famous ninth-century Japanese poet Ono no Komachi, who was noted to be a rare beauty.
 * While there is no limit to the needles Komachi throws, she only has six visibly holding her hair up.
