Midori

was a chūnin from Kusagakure.

Chūnin Exam Arc
He and Shiba were the personal guards of an unnamed daimyō during the Chūnin Exams. They were assigned to make sure Gaara lost to Sasuke Uchiha, making their daimyō win a bet with another daimyō. When they threatened Gaara to lose, they greatly offended the young jinchūriki, who proceeded to brutally crush Shiba to death, and then Midori, who tried to flee in terror, died shortly after; his death was witnessed by Naruto Uzumaki and Shikamaru Nara, who were too scared to take any action as Midori screamed for help in vain as he was dragged back into the hallway to die like his partner. Shiba and Midori's deaths managed to quench Gaara's blood-lust, thus saving Naruto and Shikamaru from suffering the same fate.
