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 Tsuba to death, and then Midori, who tried to flee in terror, died shortly after. Their gruesome deaths quenched Gaara's blood-lust, which saved Naruto Uzumaki and Shikamaru Nara from the same fate.
