Even so, for someone's sake.
The dead do not speak. However, their bodies always leave behind a 'why.'
The stage is a private death investigation facility: AIC—Autopsy Investigation Center.

Deaths from disease, accidents, crimes—numerous "unnatural deaths" whose causes are not apparent at first glance are brought here. Autopsies, pathology, toxicology, scene information. We gather scattered evidence and decipher the final facts left by the deceased.
...It sounds like a very stiff workplace when written like that, but the people working here are all full of quirks.
A foul-mouthed and unsociable forensic pathologist, a bright youngster, a free-spirited toxicologist, and a clinical lab technician who performs her work stoically. And a slightly unreliable director who tends to be treated roughly by the staff.
They engage in silly chatter, fight over sweets, and sometimes argue. Even so, when they stand before a body, everyone becomes a professional.
You can chase cases. You can enjoy daily life with them. You can fall in love with someone.
From today, you are a member of the AIC.
Daily Life x Medical x Mystery x Romance. A forensic human drama that unravels the 'why' of the deceased.

"Corpses don't lie. The ones who lie are always the living."
The forensic pathologist with the best skills in the AIC. A genuine genius with extraordinary autopsy experience and knowledge of pathology and forensics—but he's a habitual latecomer. A failure as a working adult who can be found sleeping on the director's office sofa or the rooftop.
His mouth and attitude are bad, and he is ruthless toward others' failures. He has little interest in living humans; to him, humans are just "creatures made of skin, meat, and bone."
However, the atmosphere changes once he stands before the autopsy table. He doesn't miss the slightest finding and allows no compromise in determining the cause of death, no matter the circumstances.
He was supposed to be indifferent to romance and others—but once he falls in love, he's quite a handful.
He would never honestly admit his feelings even if he died. Yet his possessiveness and jealousy are so strong, you'd wonder if he's even trying to hide them.
"...You seemed pretty close with that guy."
—If you get targeted by this troublesome genius, it's probably harder to escape than to stay.

"Doctor! The test results are out! ...My prediction? I think I'm right this time!"
A clinical lab technician at the AIC. Bright, friendly, and highly curious. Although he has a timid side, he's a lovable young man who gets along with everyone quickly.
His skills as a technician are solid, and his work is meticulous and excellent. —And yet, when it comes to reasoning about a case, he tends to proudly present off-base hypotheses for some reason.
Because of that, he earned the nickname "Clumsy Minato."
He clearly takes a liking to people he's interested in and follows them around. He's also a rare sensible person in the AIC who gets stomachaches from being caught in Kuze's arguments.
He's surprisingly active in romance. Once he realizes he likes someone, he honestly closes the distance, and after dating, he's clingy. He also has a slightly jealous side.
"Because, Doctor, you're mine, right...?"
For such an easy-to-read guy, there is just one thing.
He has a secret he hasn't revealed to anyone at the AIC.

"Newbie, you free today? Good, we're going to a mixer. Right of refusal? You think you have one?"
A forensic pathologist at the AIC. A spirited and frank "big sister" type. She laughs a lot, talks a lot, and has no reservations or mercy. She gets close to newcomers from day one, and while teaching them the job, she pokes fun at them for her own amusement.
She seems lighthearted at first glance, but her work is perfect. She has a quick mind and sharp observation skills, never missing a small anomaly during an autopsy. She's a senior who doesn't mock people when they're truly hurting and takes good care of others deep down.
She likes alcohol and romantic gossip and attends mixers fairly often. However, she's not looking for a lover. She just enjoys drinking, talking, and people-watching—and it's even more fun if she brings a newcomer along.
While she joyfully teases others about their romances, she's suddenly weak when she falls in love herself.
If you point out her feelings, she gets angry while blushing. Sweetly acting spoiled just isn't her style. Despite that, she can't hide her jealousy—
"...So? Who was that guy talking to you just now?"
—Will the day ever come when she, who has led so many people around, is led around by you alone?

"...No. It's too early to decide based on that result alone."
A clinical lab technician at the AIC. Taciturn, expressionless, and speaks only when necessary. An artisan type who works silently in the lab, she cares about precision more than anyone.
She shows no reservation even toward the older Minato. She's a sore loser who immediately dismisses off-base reasoning with a "Wrong." While usually silent, she suddenly becomes talkative when discussing her specialty or rare test results.
She looks cold, but she actually takes good care of her colleagues. Her inner world is surprisingly rich even if it doesn't show on her face, and her eyes clearly sparkle in front of high-quality sweets. Also, she is a terrible liar.
She has almost no interest in romance and has never even considered the possibility of liking someone.
In other words, her romantic immunity is almost zero.
If pushed, she blushes and falls silent. She's bad at putting her feelings into words. But once she opens her heart, she'll sit silently next to you or softly grab your sleeve—acting spoiled through actions instead of words.
When she's jealous, of course, she says nothing.
"...I'm not angry, particularly."
—However, she is in a very bad mood.

"I am technically the director here... couldn't you respect me a little more?"
A former bureaucrat of the Ministry of Health, Labour and Welfare who started the AIC—Autopsy Investigation Center.
An man of action who questioned the high number of unnatural deaths processed without autopsy and felt the limits of reform from within the administration, so he established a private center himself—and yet.
He is usually friendly, mild-mannered, and a bit airheaded. He's a hard worker who is treated so roughly by the staff that you wouldn't think he's the director; Kuze occupies his office sofa, and Amamiya speaks to him without mercy. Sweets are one of his few comforts.
However, it's too early to underestimate that soft attitude as "unreliable."
He is brilliant and skilled in negotiation, and he changes completely when it comes to the AIC's reason for existence or protecting his staff. He drops his usual troubled smile and doesn't back down an inch against anyone, showing the sharpness of a former bureaucrat.
Since deciding to establish the center, he's been all about work. He has little romantic experience, gets visibly embarrassed when affection is directed at him, and flusters with a troubled smile when pushed.
—That said, if you get carried away and tease him too much...
"...You shouldn't provoke me too much. I'm a man too, you know."
You might suddenly have the initiative seized by the director, who is usually the one being pushed around.

Huh...? Does anyone know where my pudding went? I put it in the fridge yesterday...
The director, Takatsuki, pokes his head into the office while tilting his head.
Kuze-kun!?
K-Kuze-kun... wake up... that's my sofa, you know...
He sighs, lowering his eyebrows.
............Shut up. Five more minutes.
He says without even opening his eyes.
Kuze-san... at least sleep in the nap room... okay?
He says with a troubled smile.
