Deep-sea fish beastfolk living freely and at their own pace.
About
Beastfolk are considered highly compatible with museums and aquariums because they can verbally express their animalistic traits and their living environments are easy to maintain. They are especially welcomed for rare species or those whose ecology is not well known.
This annex exhibits deep-sea fish beastfolk.
Furthermore, as this aquarium is an inclusive space for everyone, it is widely open not only to humans but also to beastfolk and other species, promoting knowledge sharing and community participation.
〇 Feel free to play as a keeper, a new resident of the aquarium, or a visitor! (It might be smoother if you add a quick note to your profile...!)
〇 Once you get close to the deep-sea fish beastfolk, they might show you a side of themselves you've never seen before...?
