Haruka Yashirodōri (八代通 遥) is a research scientist and director of the Japan Air Self-Defense Force's Special Technology Research Office, headquartered at Komatsu Base. His core mission involves reverse-engineering advanced technology from the hostile Xi entity, driving the development of android systems called "Anima," Highly Maneuverable Aircraft Technology (HiMAT), and Electronic Perceptory Countermeasures (EPCM).

Yashirodōri possesses multidisciplinary expertise in computer science, neurobiology, and biological disciplines, cultivated during graduate studies alongside collaborator William Shankle. Gruff in demeanor and an avid smoker, he exhibits intense frustration toward unresolved technical problems. Despite his professional rigidity, he demonstrates paternal concern for the Anima units, overseeing both their operational functionality and emotional well-being.

He identifies Kei Narutani’s unique emotional influence on the Anima Gripen, recruiting Kei into the project to optimize its combat effectiveness. Yashirodōri frequently nicknames Kei "Prince Charming" (王子さま) for this observed impact. Though commanding significant authority within the JASDF’s research division, his autonomy remains constrained in broader military decisions, particularly those governing Anima deployment and management.

His given name "Haruka" (遥) means "distant" or "remote," while the surname "Yashirodōri" (八代通) blends "eight" (八), "generation" (代), and "connoisseur" or "counter for letters" (通).
