Kosuke Maruboshi

Kosuke is an elderly man with his once black hair, now greyed which he wears in a short ponytail. He wears a mesh armour shirt under a short, brown, sleeveless kimono with a pair of grey pants. He carries a wok that he uses for multiple reasons ranging from cooking in while out on missions, to supplementary weaponry during battle. He also carries a ladle, and a sword sheathed horizontally across his lower back. In his youth, Kosuke had dark hair, tied in a ponytail. He wore a blue jacket along with a mesh shirt underneath.

When he was still a child, he made a reckless decision that cost him the lives of his teammates. 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. Kosuke would remain a genin for over fifty years, thus the reason others called him the Eternal Genin. During this time, Kosuke would serve under the Second, Third, and Fourth Hokage. At other points, he fought alongside the Legendary Sannin, Konoha's White Fang, and the previous generation of Ino-Shika-Chō trio. He also seems to be one of the few people who knew about the true identity of Naruto Uzumaki as the Fourth's son. At some point he lost one of his legs, presumably in battle, and had it replaced with a sword he conceals with a prosthetic foot. Six years after the Fourth Hokage died saving Konoha from the Nine-Tails, Kosuke was sent on a mission with Might Guy to complete a trading of secret scrolls with the Land of Wood's Prajñā Group to establish an alliance between the two countries. Along the way, Guy noted his suspicions that this mission was actually to test the trustworthiness of the other country. Ultimately, Guy's guess was right as the Prajñā Group betrayed the Konoha-nin after getting the scroll. As Kosuke and his team were nearly crushed by the enemy, Kakashi Hatake and Itachi Uchiha of the Anbu appeared to save their allies and swiftly defeated the Prajñā Group. Seven years later, 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. While on the mission, they realised that their borders were invaded by several Iwagakure shinobi. After being left by both Hayama and Tekuno, to report to the village what had happened while they held them off, they were confronted by two Iwagakure teams that had broken through the defensive lines. After defeating the teams with various techniques, Kosuke directly clashed with the attack force's leader who mistook him to be the leader of Konoha's defence forces as well. After Naruto returned claiming that he could never abandon a comrade on the battlefield, Kosuke declared that he would neither die, nor allow Konoha to be besieged by someone who would so willingly sacrifice their subordinates. With this, he defeated the Iwagakure kunoichi. He was later given a mission on retrieving valuabe infomation from Iwagakure. After retrieving information from the Three Brothers from Iwagakure, Kosuke rushed back to Konohagakure to relay the information. He was, however, overpowered by them and when seemingly trapped, Team Asuma arrived as back up and saved him with their Formation Ino–Shika–Chō.
