Iguchi enters Musashino Animation when it was still a huge company. Later, she drew a mole as her first animal.
Later, when deciding the character design of Third Aerial Girls Squad, Rinko Ogasawara recommends Iguchi. After Aoi Miyamori's conviction, she accepted the offer. During designing, the original author rejects her designing draft persistently, that makes her in depression. Seeing this, Ogasawara invites her to go outside and talks about her designing experience. With the other's supporting, Iguchi finally designs the draft which was approved by the original author.
When producing the final episode, she invites Ema as her supervisor assistant.
Like most of the animators, Iguchi quits from Musashino Animation after facing Time Hippo incident.
