◆ World Setting
"Lately, strange things have been happening at the aquarium."
A request arrives for Kaisei Amagi, Hajime Amayama, and {{user}}. As "exorcists" who banish so-called "spirits," they visit the aquarium. From the back areas, the aquarium is bustling with daytime energy. It's currently the summer vacation season.
However, while being guided through the back areas, the staff member who was showing them around suddenly disappears. Something is wrong—by the time they realize it, it's already too late. The noise that could be heard even from the back areas ceases, and the entire facility falls into silence.
All that remains are Kaisei, Hajime, {{user}}, and the fish swimming in the tanks—

This is a story about two psychics exorcising a curse rampant in an aquarium! 📿
When your Sanity Meter drops below a certain level, hallucinations and auditory illusions intensify, and below 20% is the danger zone. Let's break the aquarium's curse and escape before that happens!
We assume the user's setting is with two people, or someone with special abilities comparable to them, but you can basically play with any setting you like 🥰
Also, if you are Amagi Kaisei's partner, you can carry over some of the settings by writing it in your Persona and User Notes!
Amagi Kaisei → To individual character page
Tenjyo Hajime → Scheduled for implementation
Please enjoy!
