Kosuke Maruboshi (�る��コスケ, Maruboshi Kosuke) is a genin of Konohagakure, whom others called the Ten-Thousand-Year Genin (万年下�, Mannen Genin). Kosuke has been a genin for over fifty years, thus the reason others called him the Ten-Thousand-Year Genin. When he was still a child, he made a reckless decision that cost him the lives of his teammates. Feeling ashamed of this, he felt he was not worthy of being promoted beyond the rank of genin. Despite this, he continued to train arduously to improve his skills, something that was insisted upon him by Tobirama Senju. During his time as a ninja, he had served under the Second, Third, and Fourth Hokage and now apparently even the Fifth Hokage. At other points, he fought alongside Jiraiya and Sakumo Hatake. Kosuke is an elderly man with his once black hair now grayed which he wears in a short ponytail. He wears a mesh armor shirt under a short brown sleeveless kimono as well as gray pants. He is usually seen with a smile on his face. He carries a metal pan that he uses for multiple reasons ranging from cooking in while out on missions to a weapon during battle. He also carries a ladle and a sword sheathed horizontally across his lower back. Even though his official ranks is that of genin, he is skilled enough to become a J�nin; a promotion he declined time and time again. He has shown considerable taijutsu skill, able to use only his cooking-ware to defend and maneuver against enemy attacks. He is also a skilled kenjutsu fighter and wields a sword and a hidden blade concealed in his prosthetic left leg, both of which he can use to strike with deadly precision. He also demonstrated the use of a unique technique which incorporated genjutsu along with kenjutsu to confuse and petrify his opponent, making it easier to strike them down. When he was younger, he was taught many techniques by the Second and Third Hokage. His training under the Second has given him highly proficient skill in high caliber water release techniques, allowing him to use techniques such as the Water Release: Water Dragon Bullet Technique and Water Release: Water Encampment Wall. He also learned the Shuriken Shadow Clone Technique from the Third Hokage. In addition to combat skills, Kosuke is a highly capable survival expert and cook. He was placed on a team alongside Hayama Shirakumo, Tekuno Kanden and Naruto Uzumaki to guard the borders of the village after Orochimaru and Sunagakure's invasion of the village. He remarked that Minato had left behind a fine son, showing that he was one of the few people who was aware of Naruto's lineage.
Kazuma also known as Furido, was a member of the Twelve Guardian Ninja, and eventually led half of the group to stage a coup d'etat against the Hokage. He was also the father of Sora.
While he was still alive, he was part of the Twelve Guardian Ninja. Ten years before the start of the series, when six of the members tried a coup d'etat, he alongside Asuma Sarutobi, Chiriku, Nauma, T�u, and Seito fought against them, only to be killed by Kazuma when Kitane and the three other lightning users tried to use Limelight on Kazuma. He along with Nauma, T�u, and Seito were known as the greatest lightning-chakra masters of their time. Like Asuma, his battle style revolved around combining superb taijutsu skill with his elemental affinity through a unique weapon. He used a three-parted metal staff to fight with, that is also able to conduct his lightning based attacks. Kitane could send lightning through the ground to attack by striking his staff into the ground. When separating his staff into three pieces he can use his jutsu Lightning Release: Thunder Binding to form a barrier around a target. When in one of the four cardinal directions, he along with Nauma, T�u, and Seito could use a jutsu called Limelight to destroy everything within that area to ash.
Yukimaru is a young boy (it is still unknown if he is a shinobi) who appears in the second Naruto Shippuden filler arc. He is a test subject of Orochimaru, because he has the ability to control the Three-Tailed Giant Turtle. Yukimaru is a quiet boy, probably due to his past, he constantly ask questions like "Is it going to be fun?".

There, Kabuto conducts an experiment where he forcibly releases the full power of Yukimaru's chakra. This results made the Three-Tailed demon to partial emerge before submerging again. Later, he is sent out again with Guren to complete a mission. During which, he succumbs to sickness, forcing Guren to care for him. As a result, he seems to have grown attached to Guren and possibly vice-versa. This is further emphasized from how Yukimaru reacted when Guren tells Yukimaru she has to head out in a manner similar to how Yukimaru's mother did before presumeably dying. He then gives her his necklaces with a special charm on it. Later, Yukimaru again bumps into Naruto, who offers for the orphan to join him in Konoha, to which Yukimaru politely declines as he feels his place is with Guren. Soon after, Kabuto returns to conduct another experiment with Yukimaru. He has Yukimaru take several medical pills. Ultimately, this finally causes the Three-Tailed Beast to emerge. He is able to controlled three-tailed beast, for the first time he has to drink the pills from Kabuto to release Three-Tails Chakra but later he manage to release it without pills. Yukimaru also has illusion technique, when he meet Naruto, white camellias appear on everywhere. Then he and white camelias (tsubaki) disappear on the same time.

Hotaru (ホタル) is the granddaughter of the former leader of the Tsuchigumo clan, En no GyÅ�ja. One day Hotaru was under attack by a group of ninja who were actually after Utakata. Utakata saved Hotaru from the ninja, but was wounded in the battle. Hotaru ran for help from her fort, saving Utakata's life, causing him to become indebted to her. After this, he became a sort of master to Hotaru in order to hide from anyone who is after him. Later she finds him sleeping under a tree and Utakata got angry when Hotaru called him master, saying that the relationship between a master and a student is not something you can count on. Utakata reluctantly begins to teach her the Water Walking Exercise first, believing that she wouldn't master it. In the morning, she shows that she was able to stand on top of the water by training all night. Next, Utakata taught her Water Release: Violent Water Wave, once again believing that she would not be able to master it without water-natured chakra only to discover she does possess water-natured chakra. She later found Utakata under a tree and showed him the she again mastered the technique much to his suprise. When a group ninja came looking for the Tsuchigumo clan's kinjutsu, Tonbee had Hotaru, along with Utakata, take the clan's forbidden jutsu so that ninja could not retrieve it. While traveling, Utakata got upset at Hotaru for calling him master (å¸«åŒ , shishÅ�), at which point Naruto arrived, believing Utakata to be attacking Hotaru. Hotaru broke up the fight and Utakata left her, deciding that Team 7 would be capable in protect her. As she watched him float away in a bubble, she tried to convince him not to leave, but was unsuccessful in doing so. While on the way to the clan's secret village, Naruto argues with her only for Yamato to devise a plan to convince Hotaru to accept their protection. Using his unique jutsu, Sai drew mountain leeches to fall on Hotaru, who freaks out and becomes afraid, causing her to accept Team 7's protection. When they reached the village, Team 7 leaves Hotaru with the Tsuchigumo clan and Hotaru thanks Naruto before he leaves. When Naruto left he saw the look on the peoples faces back at the clan's village, so he decided to return to check things out. Source: naruto.wikia.com

He is a subordinate of Guren He is unsociable and quiet, making people unable to figure out what he is thinking, but his battle skills are without a doubt very dexterous. He relies on taijutsu and brute strength and preferred fighting alone. He holds a special sentiment towards Guren and was her most loyal subordinate, even stating "I will accompany you no matter where you go". The reason for this was that Guren saved his life while he was imprisoned by Orochimaru, giving him water when he was dying of thirst.
