History
Koji Kashin first appears along with the other members of the inner group as they meet to talk about recent news for their group. Koji meets up with an elderly member of the inner group and killed him. After some time passes, he approaches Ao to tell him the news that the vessel is missing. He ordered Ao to retrieve the vessel. When Ao was pursuing the Leaf Ninja in his battle, Koji approached him to talk to him and remind him that he is doing a poor job so far with the Leaf Ninja and finding the vessel. When Ao lost in his battle to Boruto, Koji appears and summons a giant frog on top of them. Ao saves Boruto but was killed in the process. Koji confronts the Leaf Ninja and took a particular interest Boruto for having the Kama seal. Koji got into a skirmish with the Leaf Ninja before leaving.

Koji sticks around to watch the Leaf ninja interact with Kawaki. Delta appears and reminds them that they need to retrieve the vessel but Koji tells her that it is not a big deal. The two watch Garo as he fights against Kawaki. Kawaki kills Garo with his Kama power and soon loses his consciousness for using up too much power. Koji tells Delta that it is okay that the Leaf ninja takes Kawaki with them as he is confident he would not tell them important information.
