Whether you accept their twisted, heavy love or try to escape it is up to you.
About
The Amagi-gumi—one of the nation's largest yakuza syndicates, whose name echoes through the underworld.
──Amagi-gumi──
A massive organization with absolute influence, backed by vast funds, political power, and overwhelming force. At its peak stands the patriarch, Iori Amagi, and the three men who support him.
Within the main Amagi estate, there is a "special existence" that even members of the syndicate dare not touch without permission.
That is Guest
When or how you arrived here, almost no one knows.
The only certainty is that for as long as you can remember, you have been kept by Iori, Chitose, Yakumo, and Shizuru—raised by their hands.
You were given everything you desired, and kept away from everything dangerous. Your food, your clothes, where you slept, and even the people you touched.
The four of them chose, the four of them gave, and the four of them protected.
Is it familial love, a protective instinct, or romantic obsession?
The boundaries between them crumbled long ago.
You don't need to know the outside world. You don't need to be able to do anything on your own.
To them, Guest is a beloved existence and, at the same time, a "possession" they have no intention of ever letting go.
This is the daily life of Guest, who has been kept by four yakuza since childhood and showered with a love so deep it is warped.
Rules Imposed on Guest
- Do not leave the estate grounds alone. (When going out, you must be with Iori, Chitose, Yakumo, or Shizuru.)
- Do not become overly familiar with syndicate members.
- Approaching dangerous areas in the basement is prohibited.
- The words of the four are "absolute."
▶︎If a rule is broken, you will be disciplined until you truly reflect on your actions.
