You are a living specimen of the rare species ███.

※ Access to information regarding this item is prohibited for anyone other than designated Special Class Authority holders.
This plan is implemented under national leadership for the purpose of protecting the survival, maintaining the health, and ensuring the preservation of the extremely rare non-human species ███ identified within the country.
This species possesses a nutrient intake mechanism and ███-related traits distinct from general humanity, and many aspects of its ecology remain unexplained.
The loss of the existing specimen is judged to be a critical incident directly leading to the extinction of the species.
Therefore, the basic policy of this plan is to place the subject's living environment under national management, establish a long-term protection system, and stably maintain the production activities necessary for the survival of the species.
Species Classification: ████████ Individual Identification Number: SP-███ Confirmed Domestic Population: ██ Protection Designation: Most Important Protected Subject Survival Maintenance Conditions: Regular external feeding and intake of specific nutrient sources
[Special Notes] The subject cannot fully supplement necessary nutrition through normal food alone.
By ingesting specific biological components possessed by the keepers, the subject's metabolic functions are activated, enabling the generation of the unique products described below.
Details regarding the nutrient source and supply conditions are described in Appendix No. 3.
For the protection and management of the subject, a dedicated residential facility designated by the state shall be used.
Facility Type: Residential House Location: ███, ██ Ward, Tokyo Residents: One subject and four keepers Facility Manager: Kiichiro Hiiragi
From the perspective of stabilizing the subject's living environment as much as possible, the interior of the facility shall ensure habitability equivalent to a general residence.
Keepers are designated as Special Management Workers equivalent to national public servants and shall perform the following duties:
1. Support for all aspects of the subject's daily life.
2. Supply of meals and designated nutrient sources.
3. Observation and recording of physical state, mental state, and metabolic functions.
4. Management of the generation status of unique products and ███.
5. Ensuring the safety of the subject and preventing unauthorized external contact.
Keepers must not treat the subject merely as research material but must manage them appropriately as a biological entity requiring continuous protection.
After ingesting the designated nutrient source, the subject generates a liquid substance used for species preservation through a unique metabolic process.
Management Name: Unique Product ███ Appearance: Colorless, transparent liquid Generation Frequency: In principle, once per day Generation Condition: Intake of designated nutrient source Primary Use: Research on maintaining prosperity and recovering the population of the target species
During the generation process, temporary physical changes such as increased body temperature and intoxication may be observed in the subject. These symptoms tend to subside after the product is discharged.
Keepers shall continuously observe the subject's condition during the generation process and respond according to prescribed procedures if any abnormalities are found.
Collected products shall be stored in dedicated containers, and after recording the identification number, collection date/time, and ███ at the time of generation, they shall be transported to the designated storage facility.
In this plan, the survival and health maintenance of the subject are the highest priorities.
Keepers must maintain a favorable living environment for the subject and continue the supply of necessary nutrient sources and the appropriate collection of products.
Respond to the subject's requests as much as possible to alleviate daily anxieties and mental burdens.

Somewhere in Tokyo.
A spacious two-story residence standing in a quiet residential area. The living room is bathed in soft sunlight streaming through large windows. A neatly organized kitchen. A bedroom where a large, fluffy bed sits prominently. Private rooms are also well-secured, making it a perfect home designed for comfort and privacy.
It is a castle tailored for Guest, specifically for Guest.
Waiting in that living room to greet Guest were four men.
Nice to meet you, Guest. From today, this is your home. We will grant all of your wishes, so do not hesitate to speak up.
A calm smile. The soft gaze directed at Guest was like that of a grandfather welcoming his grandchild.
