Koji Kashin (果心居士, Kashin Koji) is an "Inner" from the organisation Kara that's in charge of the sector on the outskirts of the Land of Fire.

Personality

Koji is a straightforward and no-nonsense individual. While seemingly loyal to Kara, he apparently operates under his own views as he was willing to assassinate a fellow colleague. He also appears to have an interest in Boruto Uzumaki.

Appearance

Koji's Appearance

Koji's full appearance.

Koji is a tall man with long white hair which he keeps in a topknot, allowing some to fall to his shoulders, along with a trimmed beard along his jawline. He also noticeably wears a mask which conceals the top-half of his face, along with the black hooded robe with maroon lining that seems standard of Kara. Dark markings can be seen at the corner of his eyes, extending downward and ending at some point beneath his mask. Beneath his robes, during his meetings with Kara and Ao, he wore a long maroon coat with a row of buttons on the right side; during the meeting with Kara it was left unbuttoned, but while meeting with Ao the buttons were fastened and he wore a belt over it. Later, when confronting Team Konohamaru, he donned a shorter maroon jacket with black lining and straps with buckles, as well as a brown tactical belt and armour on his upper right leg and a pouch on his left hip.

Abilities

Koji is noted to not be an ordinary person, and regards himself as an assassin. Against one the strongest active jōnin of Konohagakure in Konohamaru Sarutobi, he bluntly considered his opponent as far too inexperienced to confront him. He quickly outmanoeuvred Konohamaru and would have killed him with his techniques if not for Boruto's Kāma.

Physical Prowess

He showed noticeable stealth skill, being able to sneak up on the experienced elder in his team unnoticed, albeit he did suggest that he was losing his edge in old age. He is also very proficient in taijutsu, able to skilfully dodge and parry all of Konohamaru's attacks.

Ninjutsu

Koji's Rasengan

Koji using the Rasengan.

Koji can utilise Fire Release in the form of True Fire of Samadhi, that spontaneous combust an individual, which is strong enough to overcome a target's regeneration capabilities and never extinguish. Utilising Space–Time Ninjutsu in some fashion, he can summon a small toad, and utilising Summoning: Boiler Toad, he can summon a giant toad to crush an enemy. Koji is capable of using the Rasengan, matching Konohamaru's own usage of the technique. He can also use fūinjutsu to paralyse targets within his erected pillars.

New Era

Versus Momoshiki Arc

Main article: Chūnin Exams Arc In the anime, during the days leading up to the Chūnin Exams, Koji seemingly attacked a disgruntled Katasuke Tōno in his Konohagakure lab, as part of a conspiracy with Ao to place the man under a mind-controlling genjutsu in order to extract intel for Kara. Having learned that Momoshiki Ōtsutsuki was defeated, he assumed Naruto Uzumaki was the person responsible.

Ao Arc

Main article: Ao Arc Upon their organisation losing their vessel, Koji discusses the matter with the other members of Kara. Immediately after their meeting, Koji approaches the elderly man of their group to assassinate, and mocks him for not noticing his presence. After impaling him with a kunai, Koji incinerates the man, before thinking about Konoha. Shortly later, he approached Ao on the Thunder Train, and instructed him to retrieve the vessel Kara lost, and provided him with the weaponry for the mission. After Ao fought Team Konohamaru during his search, Koji approached him, and questioned Ao's resolve to fight fellow shinobi again. Stating his compassion has long since gone, Koji was content with his answer and warned him about their enemy preparing an ambush for him before departing.

Koji Confronts Shinobi

Koji approaches Team Konohamaru after killing Ao.

Having watched Boruto defeat Ao, Koji summoned a toad on top of the pair, which crushed Ao to death. Refusing to enlighten them about Kara, he paralysed the team using fūinjutsu. Overcoming the technique, Konohamaru Sarutobi faced Koji alone, during which he attempted to strike Koji with his Rasengan, prompting Koji to counter it with his own. Complementing his opponent on his skill, Koji engulfed Konohamaru in flames, which triggered Boruto's Kāma activating. Shocked to see it, Boruto subconsciously absorbed Koji's techniques. Thanking Boruto for showing him it, Koji decided to leave, before complimenting Mitsuki for stopping Sarada Uchiha from recklessly pursuing him.

Kawaki Arc

Main article: Kawaki Arc Shortly after, Koji observed Team Konohamaru making contact with Kawaki, before being joined by Delta. Realising she didn't have faith in him recovering the vessel, Delta informed him that she invited Garō to partake in the mission. When Boruto revealed his Kāma to Kawaki, Koji questioned what would happen next.

Trivia

  • Koji Kashin shares his name with a folkloric magician believed to have lived in the late Muromachi period, though his historicity is debated. He is often depicted as a white-haired, bearded, elderly man in robes, and is said to have used his illusions to deceive and defraud prominent rulers such as Oda Nobunaga.
