Shiranami

is the boss of the Magaki group and a former member of the Tsuchigumo Clan, whose goal is to obtain the clan's forbidden jutsu.

Personality
So far, it is shown that he is rather calm and patient. He seems up-to-date on whereabouts and plans of Hotaru. Also, he views the forbidden jutsu highly, believing it only a nuisance to others. Shiranami also appears to be narcissistic, not carrying the slightest bit about morals and other people's feelings, as shown from nonchalantly enslaving an entire village, and even killing his own father for his own goals.

Appearance
Shiranami has black shaggy hair with bangs that hang over his eyes and frame both sides of his face and pronounced creases underneath his eyes, not unlike Itachi Uchiha. His eyes are green with no eyelashes. In addition, he is tall and well-muscled. His clothes include a high-collared blue cloak, with the same leaf symbol that appears on En no Gyōja cloak (a symbol of his worthiness to wield to the clan's forbidden jutsu), a black top that ends mid-chest and dark casual pants.

Abilities
Shiranami's abilities are mostly unknown. He is however considered an immensely gifted ninja, who from a young age showed his talent and quickly surpassed his father, who was also known for his natural talents in the ninja arts. Shiranami is also shown to be very calculating and methodical, capable of creating well-thought out strategies. He also is shown able to create various powerful jutsu, some of which he taught to his subordinates. He has impressive stealth skills, either hiding in the shadows unnoticed or using a unique spying jutsu. Shiranami also possesses advanced sealing jutsu prowess, able to subjugate anyone he brands with his mark into mindless puppet.

Six-Tailed Beast arc
He first appears, albeit his face mostly hidden, giving his fellow Magaki orders to find Hotaru and the kinjutsu, saying it will make them wealthy and that it was just a nuisance to the rest of the world.

After Hotaru's return to Tsuchigumo village, he is among the villagers who encircle her while the Tsuchigumo chief is talking to her.

Later, when Hotaru manages to escape Akaboshi and the other Magaki with the help of Utakata, Shiranami meets up with his comrades, with his face fully shown this time. After they report what happened, Shiranami hands over a Bingo Book on Missing-nin from Kirigakure, in which Utakata is listed. The bounty on his head is 50 million ryo. When asking Shiranami for further orders, he also wonders what to do. While tracing Hotaru, keeping his presence hidden, he finds ANBU from Kirigakure attempting to arrest Utakata. He decides not to do anything else yet and leaves.

Shiranami begins spying on Team Yamato to gather more information. He later becomes deeply concerned when discovering there is a way to destroy the forbidden jutsu, which Hotaru and Team Yamato were considering to do. Much to his joy however, Hotaru offers an alternate choice, of seeking out Shiranami himself, as Hotaru is under the belief he is still loyal to Hotaru's grandfather.

Adjusting to the new situation, he had his mean intercept Naruto while he approached Hotaru, who went in search for the missing Utakata. Upon meeting her, he acted sympathetic to Hotaru's feelings, telling her that he to wanted to restore the clan. While Shiranami was able to convince her not to destroy the jutsu, Hotaru still decided to inform Tonbee of her change of heart. Not wanting anyone to interfere, Shranami sought to intercept her message and knocked out Hotaru, bringing her back to the clan's village, which he already took complete control of with a form of sealing jutsu. While he had his men keep guard, Shiranami began to process of removing the forbidden jutsu.
