Early life[]
At various points in her life, Mayumi got married and established and/or became the owner of Matsushita Diner. Around 1995, she gave birth to Ota Matsushita.
Mayumi continued her work at the family establishment as her son grew older and eventually befriended Iris Sagan and Mizuki Okiura.
At some point in her life, possibly in the mid 2010s, Mayumi became ill with alzheimer's disease specifically resulting in progressing dementia.
New Cyclops Serial Killings[]
Ota Route[]
In the Ota Route, Kaname Date enters her somnium; PSYNCIN' IN THE SUSTaiN. This somnium allowed the player to experience her important memories. Her dementia caused her to forget Ota Matsushita's involvement in the attempted murder of both Iris Sagan and Ota Matsushita in the Okiura Fishery Cold Storage Warehouse. She later is able to remember the events that transpired, revealing that she had called a taxi to follow after Saito Sejima (In the body of Iris Sagan) and Ota Matsushita. This lead her to believe that Ota Matsushita was the culprit behind the attempted murder, which caused her to attempt to feign guilt to protect him.
Retirement[]
Mayumi retired after the case of New Cyclops Serial Killings solved, as her son took over the job of Matsushita Diner. What is known is that she received treatment at the Central Hospital after the case and was accompanied by a nurse named Hanayo Nasu.
Since then, Mayumi has often stayed in the rest area at the back of Matsushita Diner for her daily activities. After the Half Body Serial Killings occurred, she was not affected.
Six years later, Mayumi becomes 60 years old. According to a driver named Takushi Ibarado who patronizes Sunfish Pocket, she appears to want to apply for a Mermaid position there...

Trivia[]
Etymology[]
- "Mayu" in Mayumi can mean "eyebrows" (眉).
- The last kanji in Matsushita (真津下), read "shita," can also be read as "ge," making her family name "matsuge" (まつ毛), meaning "eyelashes."
General[]
- In a fan-made Character Poll for AI: THE SOMNIUM FILES held on Twitter, Mayumi Matsushita came in 11th place.
- In Day 2: Saturday —saikAI—, Date asked Mayumi if Ota had a cellphone, to which she replied that Ota wasn't allowed to own a cellphone. In the original Japanese text, Mayumi did not recognize the word "cell phone" and assumed Date was speaking a different language. This line is potentially an early hint at Mayumi's dementia, or an indicator of how out-of-touch she is with the youth.
