Genma Shiranui

is a tokubetsu jōnin-level shinobi from Konohagakure who serves as an elite bodyguard to the Hokage.

Background
When Genma was a genin he was put on a team with Might Guy and Ebisu. At one point, they were confronted by a generation of Seven Ninja Swordsmen of the Mist, only to be saved by Might Duy. During part of their chūnin exams, his team confronted Team Minato. Other than that, not much is known about Genma's background except for the fact he is an elite guard to the Hokage. During his time serving under the Fourth Hokage, he was taught the Flying Thunder God Technique.

Personality
Genma is shown to be very calm, impartial, collected, proud and casual. He is never seen being boisterous or lost in difficult situations and is confident enough to take charge of large groups of ninja. It was also stated that he hates Orochimaru for power-playing. He is also a jovial person, prone to wisecracking at times. When Shikaku Nara contacted him, he made it a point to first tell Genma not to make fun of the situation.

Appearance
Genma has brown, shoulder-length hair which hangs about his face and brown eyes. He wears his forehead protector like a bandanna, and the standard jōnin outfit and always has his trademark senbon in his mouth. As a genin, he wore a dark, baggy outfit with a hooded red and black jacket. He also wore a strap around his leg and a senbon in his mouth.

Abilities
As a well noted veteran shinobi, Genma is known for taking part in difficult missions because of his skills. Though he has only been seen in a handful of fights, 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 his status as a guard for the Hokage, and the fact 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. Even after the fight, while the Sound Four were resting, they noted that they wouldn't have won without using the second stage of their cursed seals.

Space–Time Ninjutsu
Genma has also shown some aptitude with Space–Time Ninjutsu as he is able to use the Flying Thunder Formation Technique which was taught to him by the Fourth Hokage due to their being part of the Hokage Guard Platoon. However, Genma has to use this technique in conjunction with Raidō and Iwashi Tatami.

Chūnin Exams
After Hayate's death, Genma proctored the final round matches of the Chūnin Exams. After Neji's battle with Naruto, Genma tells him that even a caged bird can eventually free themselves. As the invasion is launched, he enquires whether or not Orochimaru was leading the assault as he faces off against Baki. After Gaara retreats from the arena he advises Sasuke to chase after him telling him that he was already at the chūnin level and to do what he must in order to protect Konoha. His fight is however interrupted when the invasion is called off.

Sasuke Recovery Mission
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. He inquires about what they were carrying since they were coming from the direction of Konoha. In retaliation Sakon throws a kunai at him but Genma deflects it with his senbon. In order to defeat Raidō and Genma, the Sound Four activate level two of their cursed seals, leaving Genma and Raidō gravely injured and in serious need of medical attention. Shizune stabilises their conditions and takes them back to Konoha for further treatment.

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

Akatsuki Suppression Mission
In the anime, Genma was present at Asuma Sarutobi's funeral, mourning his death.

Pain's Assault
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.

Fourth Shinobi World War: Countdown
In the anime, Genma is present at the war council meeting that Tsunade convenes.

Fourth Shinobi World War: Confrontation
Genma along with Raidō were tasked with guarding the daimyō at their safe house during the Fourth Shinobi World War. While on duty, he and Raidō conversed about the daimyō and their medal-naming argument that was going on. He told Raidō not 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 told him that if he just stood around thinking of medals, he'd never get one though, and to stay alert as they were going to relocate soon.

After Black Zetsu located the daimyō he was intercepted by Mei Terumī. Genma alongside Raidō, Chōjūrō and the rest of her team arrived shortly after. When Naruto's shadow clone arrived on the battlefield, and crashed head first into a tree after Black Zetsu sidestepped him, Genma agreed with Raidō's sentiments that Naruto had not changed much and still rushed into a fight without thinking.

Fourth Shinobi World War: Climax
While battling Black Zetsu, he marvelled at Chōjūrō's skill with his sword. He was later contacted by Shikaku who before beginning immediately told him not to makes any jokes because they were in dire straits. However, after telling him that the real Madara Uchiha had been reincarnated to the battlefield, Genma claimed that he couldn't help himself this time. As he, Raidō and Iwashi prepared to transport Mei using Minato's Flying Thunder God Technique as per Shikaku's orders, he explained to her that he was part of the Hokage bodyguard detail and as such was taught how to use the technique by the Fourth during his rule. As soon as Tsunade — who was marked with the technique's seal — had been transported to the battlefield, they performed the technique and stood behind the other Kage as they confronted Madara.

As Mei and A engaged Madara in battle, Iwashi prematurely anticipated his defeat, Genma however, noted the extent of damage inflicted upon the surroundings by the enemy and warns his partner to stay focused while Raidō commented that there is no way to just force their way through. Dodai then enlisted their help to go after the Kabuto-controlled Mū who had began to emerge from the debris. The four men then give chase to the Tsuchikage but their target is soon slapped away by A during the Raikage's assault on Madara. As the battle between the Kage and Madara waged on, they continued to give chase to the evasive Mū.

With the Impure World Reincarnation released, Genma watched alongside his comrades as Mū was enveloped in a light of sorts before beginning to deconstruct.
