Story

PSYNCIN' IN THE SUSTaiN is a Somnium based on Matsushita Diner.

It is the thirteenth chapter, the fifth and final Somnium of Ota Route. It is a Somnium created from Mayumi Matsushita's dream by the Psync Machine. ABIS investigated this Somnium to gain additional information about Mayumi's involvement with the attempted murder of Iris Sagan and Ota Matsushita.

History[]

Aiba and Date entered the Somnium and found themselves, along with Mayumi, were in a blank space, and then the corner of Matsushita Diner appeared there. Date believed that they need to reproduce Mayumi's previous memories here to obtain important information, and Aiba called it as his "intuition."

Heard about Mr. Matsushita's death.[]

They first found themselves in a time 2 months ago, at September, and then investigated the Sliding Door, recreating the memory of when Ota came home one day from 2 months ago. He ignored his memory-impaired mother's greeting, responded to her badly and walked straight into the house.

Then, time started to go backwards, reached 5 years ago, 2014. Another corner of the house appeared, where Aiba and Date thought there was a sad memory of Mayumi. They investigated the phone at the bar and discovered a memory of Mayumi learning about Takero Matsushita's death over the phone call 5 years ago.

Cheered for Ota.[]

Time came 6 years ago, 2013, the year when Ota turned to 18 years old, and another missing corner of the room was restored. Aiba and Date investigated a cake that appeared on a dinner table, reliving memories of Ota's parents celebrating him when he was admitted to a university six years ago.

Determined to do my best.[]

After recreating this memory, the time came to 7 years ago, 2012, a year after the Kabasaki Chemical Plant explosion event. A bank statement, Matsushita family's loan, appeared on the desk in the corner. Aiba investigated it, recreating the memory of the Matsushita couple borrowing money for their livelihood during the year. They said they would work harder, stick to supporting Ota's dream.

Gave the chocolate to Ota.[]

Next, the time went back to 15 years, 2004, and Aiba wondered again whether reliving these unfortunate memories would have a bad effect on Mayumi, but Date insisted on continuing to investigate. They found and investigated some stickers stuck to a shelf before Ota, 8 years old at that time, appeared and said "did you get it for me?" Aiba asked if it meant some kind of chocolate, and Ota answered yes, the Odoroki-man Chocolate. Then, Mayumi appeared on the side and replied to Ota that she bought Momonoki-man chocolate back to him. Ota angrily said it wasn't the brand, and after his mother mistook the Odoroki-man as Momonoki-man again when reassuring him that she would bring the right one next time, he insulted his mother and ran away, leaving Mayumi helplessly begs her son to come back.

Turned the time forward.[]

After viewing this memory, Aiba and Date found themselves in a dark space. There was only a wall clock and Mayumi, kneeling down on the ground and confiding in despair that there was nothing she can do, begging her husband not to abandon her. Upon seeing this, Aiba accused Date of recreating all this trauma, but Date still insisted on his idea. He said that since Mayumi values her family so much even so, there must be a special memory hidden behind it, saying this was the intuition he mentioned at the beginning. Trying to calm Mayumi's trauma, Aiba found the wall clock in the darkness and turns its hands clockwise.

Mayumi found the most precious memory hidden deep in her heart.

A light appeared in the darkness, and Mayumi hurried towards the light. There she met her 8-year-old son Ota and her husband Takero, from 15 years ago, whom were presenting the Mother's Day gift as Ota's compensation for his rude attitude before - the floral pattern kitchen knife. Touched, the family hugged each other tightly. Aiba agreed with Date at the end that his intuition did work.

Name[]

  • The name "PSYNCIN' IN THE SUSTaiN" refers to Mayumi Matsushita's desire to sustain her ailing memories, disappearing due to her dementia.
  • The name of the Somnium's achievement, "SUSTaiN: Indelible Memories", means that the memory of receiving Mother's Day gift from Ota and Takero 15 years ago, as one of the only memories she cherish, will never be forgotten and erased in Mayumi's mind.
