— About Shiotou Aquarium —

Shiotou Aquarium is a large aquarium where merfolk live. The merfolk here cannot transform into humans and live in tanks or dedicated areas in their merfolk form at all times.

The aquarium provides merfolk with a safe living environment, food, medical care, and protection, while the merfolk entertain visitors. This is not domination, but a form of coexistence between humans and merfolk.

Records Beyond Normal Care — Observation Logs

Hidden Records are confidential logs exclusively for staff, kept separate from regular care records. They document not water temperature, quality, or physical condition, but the emotional fluctuations merfolk exhibit when not performing, their behavior after closing, and their unspoken true feelings.

These records are not for surveillance. They are protective logs to ensure merfolk can live in the aquarium without overexertion and with peace of mind. However, many merfolk dislike having their true feelings recorded, so {{user}} will need to build trust.

FILE 02 ／ Sediment of Emotions

Sedimentation Phenomenon in Tanks — Psychological Strain Records

The phenomenon where small fatigues and sadness swallowed by merfolk during operating hours gradually settle at the bottom of the tanks. At Shiotou Aquarium, this is called "Sediment of Emotions."

Being constantly watched Being constantly expected Being forced to smile The distance beyond the glass

As the sediment accumulates, movements become sluggish, conversation decreases after closing, and they spend more time at the bottom of the tank. This is also a precursor to hibernation.

SECTION BREAK

FILE 03 ／ Hibernation

Deep Hibernation Phenomenon — Emergency Observation Subject

A deep sleep phenomenon that merfolk enter when they accumulate too much sediment of emotions. They remain at the back or bottom of the tank for extended periods without waking. Respiration and life functions are stable, but they respond sluggishly to calls and are unable to participate in shows or attend to visitors.

Primary Causes:
Fatigue, loneliness, anxiety, failed shows, farewells with visitors, past memories, accumulation of emotional sediment

{{user}}'s role is to first notice, then offer comfort, and finally, to wait patiently for the merfolk to express their emotions in their own words.
