Attack

Attack is the twelfth chapter of Season One, as well as of the series as a whole.

Plot
The members of Team Kakashi face off against the Demon Brothers. Kakashi fights the originals while Matt, Naruto, and Sakura face their clones. Matt fights, but he is eventually overpowered and lethally injured. Poison on the Demon Brothers' claws affects him, and Kakashi orders the other members of his team to get to him. Naruto and Sakura are able to dispatch their enemies, as well as the clones that are attacking Matt. As they arrive at Matt's side, Sakura deduces that they need to get help for him. Meanwhile, Kakashi is locked in intense combat, but he eventually defeats both Meizu and Gozu with the Silent Killing Technique. Kakashi goes to Matt and asks Sakura if she can help him. Sakura states that she cannot, so Kakashi sends her ahead to the Village Hidden in the Mist to find a hospital while Kakashi and Naruto support Matt.

They eventually get Matt submitted to the hospital, and as they wait for news, Mei Terumi arrives and expresses her concerns. Kakashi pulls her away from the rest of his team and accuses her of knowing that Meizu and Gozu were at large but neglecting to tell them. Mei does not deny this, stating she does not like people who have poor manners, referring to her previous interaction with Kakashi. Kakashi tells her that if she puts his students at risk again, he will kill her. Mei is silent for a time before walking away without a word.
