SeaBed is a yuri-themed mystery visual novel told through the perspectives of
three separate characters: Mizuno Sachiko, a designer plagued by hallucinations
of her past lover; Narasaki Hibiki, Sachiko's friend and a psychiatrist
researching the workings of human memories; and Takako, Sachiko's former lover
who has been rapidly forgetting her past, including how or why the two women
drifted apart despite being together since childhood.
All three live in different worlds, but seek the same goal. To separate truth from illusion. To make sense of their own lives.
I saw a ghost in the living room.
But as I was already used to the phenomenon, I did not let it interfere with the preparation of my evening meal.
The ghost ate my fried egg and commended its taste.
As I listened to her talk, my memories drifted back to the days we were still together.
Back when we were in school, she asked me what was necessary for the two of us to be together.
A small workplace that we could make a living from without relying on anyone.
A silent apartment where we would have the freedom to do what our hearts desired.
I told her that.
In the late eighties – during the economic boom – the small design company we founded was doing surprisingly well.
We visited all the places we talked about when we were in school – the southern islands, the old European cities, the West Coast. We went wherever we wanted, seeing whatever we sought.
Alone in that spacious living room, I attempted to figure out why it all ended this way. Why those days when nothing could stand in our way faded into the past.
I no longer felt like I could do everything.
The world had grown complicated. Even simple matters became difficult.
The rules we had established in the past no longer seemed to apply, and the castle we built for ourselves crumbled to dust.
"What is necessary for us to be together?" – the ghost asked me.
We need a make a new place for ourselves.
A place no one can destroy.
Let's make it a place that no one else can reach.
And so, I inconspicuously proceeded with the plan.
In a place so deep below the surface that no one else can find it.
"At times, I'd wake up at night and hear all the sounds around me as if they were amplified. I'd feel like my head could burst at any second."
Although she moved to Tokyo straight after graduating university in order to seek employment, Mizuno Sachiko soon quit her job to establish Clover Design with her childhood friend Takako, becoming its young CEO.
Her main hobby is reading, but only because nothing else manages to interest her. Although Sachiko used to be quite an avid reader during her school years, finding a job means she now only opens a book every once in a while, whenever her schedule allows it.
After meeting Takako – an inexhaustible source of enthusiasm, as well as a stark contrast to her own personality – during her childhood years, Sachiko’s interests began to shift to whatever the other woman was doing at a given time.
"This is as good a time as any, so let's check it out."
Endlessly interested in and enthusiastic about the world, Takako gives the impression of a woman perpetually stuck in her childhood.
She fell in love with Sachiko at first sight back when they first met at the age of five. However, she does not identify as a homosexual, stressing that Sachiko simply happened to be a woman.
Takako discovers that she suffers from developmental amnesia, a condition that severely impairs her ability to recall many of her memories.
"I just like observing people."
A psychiatrist at Narasaki Mental Clinic. She was Sachiko's classmate and friend during her elementary school years, but the two drifted apart as they enrolled in different middle schools. After learning that Sachiko has been experiencing hallucinations, she takes it upon herself to treat her.
She is extremely picky about her brand of coffee, perhaps because the beverage serves as her sole companion during those long hours spent immersed in research.
Though not religious, she is a strong believer that everything happens for a reason, and all things have their place and order in the grand scheme of the world.
