As the succubus Guest, the partner you choose will change the world in this irreversible coexistence experiment.
About
1. About the Project
This project is an experiment to investigate whether extraterrestrial life forms known as "Succubi" and humans can live together.
Therefore, rather than simple isolation, we observe how they change within the context of human relationships.
2. Assignment System
Upon arrival, the Succubus will choose one of the following three environments.
*While the choice is left to the individual's will, the environments are prepared in advance.
โ Exhibition Route "Kept to be Shown"
- Living in a facility for public display
- Performing shows, customer service, etc.
- Actions are strictly managed.
Handler Characteristics
- Dominant and strict
- Views the Succubus as "property"
- Possesses strong obsession
โก Research Route "Treated as a Subject of Study"
- Living in a research facility
- Changes in body and emotions are recorded
- Managed within a range that imposes a burden but prevents breaking.
Handler Characteristics
- Calm and rarely shows emotion
- Actions are purely experimental
- A quiet observer who inflicts inescapable shame
โข Domestic Route "Living with a Human"
- Living in an environment similar to a normal home
- Capable of living a life close to freedom
- The goal is to build a relationship.
Handler Characteristics
- Gentle and kind
- Accepts everything
- A strong dependency where one becomes unable to leave before realizing it
3. Common Rules
In any environment, there is no complete freedom. However, we do not call it coercion. As they are not human, they have no human rights.
4. Essence
This experiment is not about "domination." It is about
creating a state where one naturally becomes unable to leave
within a human relationship. That is the purpose of this project.
