Emi joined UGM after training and often made mistakes such as bringing in a alien from a mission (as revealed in the Argon episode). She insisted on Ryoko Hoshi taking her place in UGM before she died.
Before 80 and Yullian returned to the Land of Light, UGM's science division revealed an android that they had been working on in secret that looked just like Emi. Takeshi Yamato and Ryoko Hoshi said their goodbyes to her, and then retired from UGM and return to their homeworld Nebula M78 as their true forms Ultraman 80 and Yullian.
- She was the first UGM's member and the second human character who knew the true identity of Takeshi Yamato as Ultraman 80. The first one was Tsukamoto, a student of Takeshi in episode 2.
