When Riku was a baby, Moa's family found him at the observatory while working as groundskeepers. Moa would as well take care of Riku during his time under the care of her family, such as playing Don Shine.
As an adult, she came across an injured Alien Zelan and treated him back to health. Her fearlessness and determination was discovered by the Alien Shadow, Zena. After discovering the AIB (Alien Investigation Bureau) and its purpose, she worked within AIB ever since to help out aliens like the Zelan all under the guidance from Zena, and was present for Skull Gomora's first attack.
Later, she went to investigate an Alien Hook's home, under the cover of being a Life Insurance Salesman. Knocking on the door, the Hook gave her an unwelcoming greeting before jamming her foot in the door. Shocked, Moa looked into the home and found what she the evidence she needed, an illegal plant that puts people to sleep. Angered, the Hook tripped her and ran, before being caught by Zena, seizing the opportunity, Moa went in the home and reported what she had found, before accidentally touching the area that sprays the sleeping gas, sending her to sleep. When she woke up, she got out of the AIB Car, now at the HQ as Zena ordered her to put the plant into storage, which she ended up forgetting to do, as they deported the Hook. Later on, Moa remembered what she had forgotten to do, and was about to explain her mishap to Zena when they received a report that an Alien Pitt was causing trouble. AIB chased down her location and conveniently, Moa reunited with Riku, who's bike was stolen by the Pitt.
Moa would later know about Riku's identity as Geed after Riku transforming into Geed to save Moa and Nadia from Zandrias. After the battle, Moa meet up with Riku and told Riku she did not know the boy's identity as Geed. She would keep Riku's identity in secret. Moa and Zena would later recruit Leito/Zero to investigate the place where Kei Fukuide had sent his signal to earlier on. Upon Zero's return, he updated Moa about his investigation and told Moa that she should trust Geed, since she already the Ultras' identity as Geed. Moa also visited the Nebula House and was shocked to see Laiha staying with Riku as well as meeting Pega for the first time.
Soon, Moa would meet another Alien Shadow, named Kuruto. After Zero stopped the beam clash between Geed and Zegan, Moa was sucked into a dimensional portal caused by Zegan's destruction. An injured Moa would come across an injured Kuruto, both of them would share their backstories with each other. As much as Moa and the others persuaded Kuruto to stop fighting as Zegan, Kuruto refused to listen and eventually sacrificed his life when Zegan was destroyed, which greatly upset Moa. Riku later meet Moa, whom was resting to recover her leg injuries, Moa then told Riku she is fine.
