Mushanokouji is the head of the research team at the 3rd division research center in the anime Coppelion. He serves as a supporting character who primarily works behind the scenes, using his expertise in computer technology and hacking to gather information and circumvent security systems. His skills are frequently called upon to aid Colonel Onihei Mishima and the Coppelion units in their missions within the irradiated Tokyo zone.

In terms of personality, Mushanokouji is portrayed as a quirky and somewhat eccentric individual. He has a notable fondness for food, often bringing up the topic during conversations with Mishima. Despite his technical prowess, he is sometimes dismissed or teased by others, such as Kanon Ozu, who calls him a gross otaku. This suggests that he is perceived as socially awkward or obsessive about his hobbies, yet he remains invaluable to the team because of his hacking abilities.

His motivations are closely tied to supporting the Coppelion operation and his friend Mishima. Mushanokouji does not appear in the field; instead, he provides critical intelligence from a secure location, enabling the frontline Coppelions to navigate dangers and locate survivors. His relationship with Mishima is one of mutual respect and long-standing friendship, as the two are depicted conversing casually about food and work. There is little information about his backstory or any significant character development over the course of the series. He remains a consistent technical support figure.

Notable abilities include advanced computer hacking and the capacity to breach high-level security systems. He has hacked into numerous secured networks to obtain data that assists Mishima and the Coppelion squads. His role is technical rather than combative, and he is never seen engaging in physical action. Mushanokouji’s contributions are essential to the plot, as the intelligence he provides often drives the next steps of the rescue operations.
