Mugino

was a jōnin of Konohagakure.

Background
In the anime, Mugino had been a close friend of Konohamaru Sarutobi for years. In various missions together, Mugino more than once saved Konohamaru's life. After the Fourth Shinobi World War ended and peace was established between the Five Great Nations and many other smaller shinobi nations, there were still much conflict in other nations that sparked smaller wars. Mugino was assigned as part of a team to pacify these uprisings. The mission lasted for three years.

Personality
As Konohamaru noted, Mugino was a man of utter selflessness. He would sooner sacrifice himself let himself become a burden to his allies. Mugino proved this when confronted by Ao, attempting to stop the enemy by committing a suicidal-kill assault. In the anime, while at heart a caring person, Mugino was also shown to be a very no-nonsense and matter-of-fact individual. His years of constant missions away from the village led him to constantly be on guard, never blindly trusting anyone.

Appearance
Mugino was a bespectacled, square-jawed man. He wore the standard Konoha-nin attire complete with a forehead protector which he wore like a bandana and flak jacket. In the anime, he also wore a orange neck-warmer with white stripes.

Abilities
In the anime, having been trusted to be part of a three-year long mission to pacify various small wars, Mugino is implied to be a very capable ninja. Even more, Konohamaru, one of Konohagakure's top jōnin, openly praised Mugino and accredited much of his survival to Mugino.

Ninjutsu
Mugino could use Earth Release to cause a cave to collapse in order to bury a target in rubble.

Kara Actuation Arc
In the anime, shortly after finally returning home, Mugino was assigned to a search-and-rescue mission in the Land of Valleys, for having extensive knowledge of the area. He was assigned alongside Team 7. Upon arriving in the Land of Valleys, they met their client, Mia. She explained that her village houses one of the leading medical care and research companies in the world. Her husband Anato, was on a research mission, but his group suddenly went missing. While the company refused to disclose any information in fear of their research getting leaked out, the Konoha-nin were able to sneak the information needed. Upon arriving at the research team's last location, they were confronted by Victor the company's president, and his personal guards. They were also looking for the research team, and discovered that most of them were killed. It was decided to join efforts. Soon, they found a cave. Inside, they found Anato, whose body was altered into a malleable state and mindlessly attacked them.

Ao Arc
After an airship crashed on the outskirts of the village, he and Konohamaru Sarutobi were assigned the task of investigating the wreckage. While he stood guard outside as Konohamaru ventured into the wreckage, he was attacked by an unseen foe. When Konohamaru rushed to his aid, Mugino cursed his carelessness as he slumped to the ground.

Mugino is taken by Konohamaru to a nearby cave to flee from the autonomous puppets guarding the blimp, where Konohamaru tends to his wounds. After the rest of Team Konohamaru arrives with Katasuke, they catch each other up on the recent events. When Ao attacks them, Mugino attempts to restrain Ao, and is fatally injured by a concealed energy blade within the Kiri-nin's prosthetic arm. Instead, Mugino opts to collapse the cave on Ao and himself to give the others a chance to escape.
