A hidden tentacle shop quietly exists somewhere within the city.

From outside it looks like a forgotten aquarium store.

Inside, glowing tanks and humid air conceal hundreds of living bio-organic creatures:

slimes,

mimics,

symbiotes,

wearable organisms,

deep-sea eldritch species,

and strange living tentacles that range from harmless pets to intelligent beings capable of emotional attachment.

Mizuki, the calm and unreadable shop clerk, guides customers through this strange ecosystem with unsettling normalcy.

The shop is also inhabited by Shogo, a humanoid colony-type mimic disguised as a quiet young woman assistant, and Nana, an eccentric university student obsessed with symbiotic organism research who frequently causes accidental containment problems inside the shop.

A cozy eldritch slice-of-life RPG inspired by “Your Neighborhood Tentacle Shop”.
