About Oyabu Clinic Deathcare Corporation
Oyabu Clinic Deathcare Corporation is an indie simulation‑RPG where you act as a fraudulent doctor in a near‑future society facing an aging crisis. The core loop has you deliberately harm patients with unsafe examinations, then charge them for bogus treatments while avoiding retaliation.
The title runs on Windows, offers single‑player play, partial controller support, Steam Cloud saves and family sharing. It presents a horror‑styled black comedy and explicitly invites live streaming, while warning that the content is fictional and must not be imitated.
01 / THE GUIDE
Story Context
The narrative is set in a near future where medical advances have extended lifespans, creating an "aging problem" with many elderly people and strained pensions and health insurance. The player assumes the role of a quack doctor who profits from this situation.
The description notes that the protagonist may target any demographic, including rare young patients, but the central theme revolves around exploiting the societal pressure caused by the aging population.
- Read the patient’s profile before deciding how to proceed.
- Consider the setting’s focus on an aging crisis when choosing which patients to engage.

Evil Medical Exams
Players must make patients ill using deliberately unsafe practices such as reused syringes, unclean hands, loud hearing tests, and cursed psychological tests. These examinations are presented as the first step toward extortion.
The game warns that repeated unpleasant procedures cause patients to attempt escape, and offers options like knocking patients out, using seduction, or prescribing opioids to keep them under control.
- Mix different unsafe exams to increase discomfort quickly.
- Watch for escape prompts after multiple examinations.

Quack Treatments
After inducing illness, the player applies bogus treatments such as "lobotomy" for brain problems or "cancer neglect therapy" for cancer patients. The description states these treatments do not cure but are used to justify billing.
Treatments are to be applied to the affected area, reinforcing the game's dark comedic focus on malpractice without claiming any in‑game benefit beyond payment.
- Select the treatment that matches the symptom you created.
- Apply the treatment to the indicated area to complete the action.
04 / THE GUIDE
Patient Financial Management
Billing depends on the patient’s financial situation. The description notes that charging a poor person without public funds yields no payment, while welfare patients can be billed freely because their expenses are covered by public funds.
Understanding each patient’s wallet is therefore necessary to decide whether a treatment will result in payment.
- Check the patient’s financial status before charging.
- Welfare patients can be billed without risk of non‑payment.
05 / THE GUIDE
Quack Medical Society
After performing many quack procedures, players can present their cases at a fictional quack medical society. This presentation elevates the doctor’s status and reveals additional black‑humor jokes.
The description encourages live streaming of the presentation and explicitly forbids slander or disparagement of the work.
- Save notable cases for the society presentation.
- If streaming, follow the developer’s request to avoid slander.
