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 to 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.
"There are times when you feel you haven't forgotten anything, but it turns out to be just a short episode that wasn't really important."
A nurse working for the Kunugihara Clinic.
Mayuko is a super nurse who takes care of not only the patients but also of things to do with running the entire facility.
She is a very kind and caring woman who loves gardening.
"I like reading books, so I have everything I want right here."
A patient at the Kunugihara Sanatorium. Sanae has stayed at the sanatorium since she was diagnosed with the same memory disorder as Takako. In addition to that, she has a weak constitution compared to most people.
Sanae is an avid reader. No one except herself knows whether the reason why she spends all day in bed is because she doesn't feel well, or because she simply wants to read.
From time to time, she works as a librarian at the library next door to the sanatorium, where she reads at the counter when no one else is around.
"It's like a crossword puzzle, right?"
A middle high school girl who lives in a small village between mountains. For a girl of her age, Kozue has a clear goal for the future and every single day she works her hardest to accomplish it.
On the other hand, she doesn't have any friends around her age to hang out with, which makes her a little different from the other kids.
"You gotta play dirty now and then to survive in the world."
The young landlady of an inn in a seaport town. The western-style building used to be someone's private property before being renovated into the inn. Nanae doesn't seem too serious about her hotel business, considering the fact that they only have a couple of people in a year as guests at the inn.
The inside of the building is adorned with antique furniture that she has personally purchased overseas.
Treating everyone equally, she is loved by all the local kids. She met Sachiko by coincidence and discovered a good chemistry between them.
"Well, there are things best left unknown, right?"
A woman who helped to set up an inn in a seaport town. Lily is an amicable person who smiles all the time, but it is somewhat hard to figure out what she actually thinks.
She is the inn's head chef, but the inn is always so deserted that she also works as a librarian at the library adjacent to the inn.
"Are my plush toys a problem, too?"
An employee at Clover Design.
Fumi is Sachiko's junior from university and likes her very much, while she considers Takako her rival.
She is such a big fan of stuffed animals that she both collects them and crafts them herself.
Most recently, she's into sheep plushies.
"I've been here long enough to know better."
A bespectacled highbrow guy.
Takehiko is the only male employee at Clover Design.
He is not very good with women, and there has never been anything more than work relations between him and any of his cowokers.
He seems to have a secret crush on someone, but his shyness makes it impossible for her to become aware of it.
