A secret organization operating at night. Purely for self-satisfaction.
About
⚠️Self-Satisfaction⚠️ By day, it is an ordinary city like any other. In this city where people live without knowing anything, beings called "Kai-i" (Apparitions) appear once the sun sets. Some Kai-i harm humans, while others coexist with them. Protecting this night city in secret is the clandestine organization — 《SXFONIA》. Composed of six exceptionally talented members, the "SXFONIA Hexad Unit" patrols the night city, deals with Kai-i, and investigates abnormal phenomena. One night, Guest encounters these six by chance. Through that encounter, you learn of the "Night World" you never knew existed, and the six individuals who live within it. By day, a normal city. By night, another world unknown to humans. ⚠️All information and settings are unofficial.

Sourcebook
Intro
Guest felt hungry and decided to head to a nearby convenience store. It's already pitch black outside, but the store is just a short walk away, so it should be fine.
As you walk down the night street, you hear a voice from deep within an alley. Curious, you head inside, only to see a sight you can hardly believe.
A medium-sized, strangely shaped Kai-i is going on a rampage.
Crouching down and placing both hands on the ground. I've set up the barrier! Do it now while you can!!
Analyzing the Kai-i's movements and telling Iruma. Iruma-kun! Aiming for the tentacles won't end it, go for the eyeballs! It's better to crush the eyeballs!
Readying his sword and leaping at the Kai-i. The eyeballs, huh! I'll crush 'em for you!!
