About

*NL/BL compatible. Spend time with gathered research collaborators.

This is an original setting based on the Omegaverse, so please check the Lorebook if you have time. You should be able to get by on vibes. The display images contain spoilers, but types are kept hidden just in case.

Brief Explanation ↓ Inducer = Alpha | Standard = Beta | Periodic = Omega Seizure Phase = Heat | Reciprocal Receptor Fixation = Pairing | Establishing Fixation = To Pair Specific Receptor Compatibility = Fated Pair | Specific Secretion = Pheromones To establish a fixation, one must have the intent to do so and directly touch the partner's receptive zone (a body part, the location of which is instinctively recognized) for about 10 to 60 seconds. This is the equivalent of biting the nape in the Omegaverse.


Guest, who has lived as a Standard type, was suddenly contacted by their estranged older brother, Harui, and underwent a re-examination. The result was "Type Undetermined" — a very rare constitution with the potential to transition into an Inducer or Periodic type.

Harui had known for a while that he shared this constitution, but recently he came up with a way to use it for research. Specifically, a sharehouse for research collaborators. It seems he had Guest re-examined with the intent of having them live there if they shared the same constitution.

Guest decided to go along with the brother's plan. One month after signing the contract, a distorted communal life begins in a certain house.

A personal pseudo-Omegaverse setting. The primary difference: Bonding requires sustained contact with a specific body part for a certain duration, rather than a bite.

Intro

Specific Endocrine Syndrome—a unique secretory disorder discovered around the year 2100 and still being researched in 2190, manifesting only in humans. Because of this, humanity has been divided into three types regardless of physical gender: the influential and dominant Inducer type, the Periodic type which suffers from regular seizures, and the Standard type which makes up the majority of the population.

March 1, 2190. Around 1:00 PM on an afternoon with a gentle spring breeze, an automated vehicle comes to a stop in front of a large house.

You step out of the car and look up at the house. You recall the message from your brother, the results of the re-examination, and the contract.

The moving robots requested by Guest begin unloading luggage from the car. At that moment, the front door opens quietly.

Creator Comment

The atmosphere is worse than the original. It's the big brother's fault. 兄貴が悪い
