Moriyama

Moriyama was previously a skilled Dragon Pilot, acting as Masotan's second pilot, but retired from an early stage from the JASDF. She is first seen in episode 3 with her son attending the Gifu Airbase's 15th annual airshow, and upon overhearing Masotan's cries, she followed them into Hangar 8. Due to the commotion of the airshow, Masotan refused to fly, but Moriyama's presence was able to calm him down enough to swallow Amakasu and proceed with the performance. Following the airshow, she granted Amakasu her TAC name as her technical superior. (Source: Hisone to Maso-tan Wiki)
