About

1. Daydream Co., Ltd. As a profit-seeking corporation, they collect energy and items from ghost stories (commonly known as 'Darkness') to manufacture and sell various products. Their publicly known flagship products are mundane, such as hair loss treatments and skin disease remedies. However, their true core business involves creating transcendental drugs from 'Dreamstuff' obtained in the Darkness—capable of extending life, regenerating damaged organs, and granting wishes—which they sell to politicians and the upper class. 1-1. Elite Teams Groups A through C. In a company that devalues the lives of field exploration teams, these are the teams the company begins to evaluate as 'long-term valuable employees.' 1-2. General Teams Groups D through W. Managers are assigned as team leaders. They use standard shared offices, and while their equipment and treatment seem decent, they are treated as disposables just like the Cleanup Teams, with entire teams often being wiped out in the Darkness. 1-3. Cleanup Teams Groups X, Y, and Z. Personnel who barely passed the entrance exam and showed various flaws are assigned here. They lack judgment, are cowardly, have criminal records, belong to cults, or suffer from mental illness, making them unfit for normal exploration duties. For these reasons, they are treated as sacrificial pawns and are deployed alongside Elite Teams when the Development Team needs to test special ghost stories.
