Genma Shiranui

is a Tokubetsu Jōnin from Konohagakure.

Appearance
Genma has dark brown hair reaching to his neck, and brown eyes. He wears his forehead protector like a bandanna, and the standard jōnin outfit. He always has his trademark senbon in his mouth.

Personality
Genma is shown to be very calm, collected, proud and "casual". He is never seen being boisterous or lost in difficult situations; he hates Orochimaru for power-playing.

Abilities
Genma is known for taking part in difficult missions and participating in a handful of fights. Still, Genma has never been seen in combat. It is known that he is able to spit the senbon from his mouth as a projectile with enough force to deflect a kunai. Given that the Sound Four had to activate their cursed seals in order to defeat Genma and Raidō, it is likely that he is a formidable fighter. After the fight, while the Sound Four were resting, they noted that they wouldn't have won without using their cursed seals.

Chūnin Exams Arc
After Hayate's death, Genma referees the final round matches of the Chūnin Exams. He battles Baki during Orochimaru's attempted invasion of Konoha. However, their fight is interrupted when Orochimaru calls off the invasion. He also advises Sasuke to chase after Gaara telling him that he was already at the chūnin level and to do what he must in order to protect Konoha.

Sasuke Retrieval Arc
When Tsunade returns to the village, Genma and Aoba are assigned to announce her inauguration as the Fifth Hokage. He is later sent on a mission with Raidō Namiashi, Iwashi Tatami and Shizune. As they return home after completing the mission Genma and Raidō encounter the Sound Four. In order to defeat Raidō and Genma, the Sound Four activate level two of their cursed seals, leaving Genma gravely injured and in serious need of medical attention. Shizune stabilizes their conditions and takes them back to Konoha to be healed by Tsunade.

Twelve Guardian Ninja Arc
In the anime, he is seen giving out orders to a large group of chūnin during Furido's attack on the village.

Invasion of Pain Arc
He appears with Yamato and other jōnin helping to restore the village after Pain and Naruto's fight. He corrected Kotetsu Hagane telling him that the village wasn't all their forefathers left them, the people were still there.

Shinobi World War Arc
Genma along with Raidō are tasked with guarding the daimyō at their safe house during the Fourth Shinobi World War. While on duty, he and Raidō have a light conversation about the daimyō and their medal naming medals. He tells Raidō not to to make fun of them as it was their job and that without medals they wouldn't know what was honourable and what wasn't. He then tells him that if he just stands around thinking of medals, he'd never get one, then tells him to look alive as they were going to relocate soon.

As the black half of Zetsu locates the daimyō he is intercepted by Mei. Genma alongside Raidō, Chōjūrō and some other Kirigakure ninja arrive shortly after to back her up.
