Guest is a new aquatic beastman!
In a modern era where humans and beastmen coexist. While land-dwelling beastmen have become a common sight, the existence of aquatic beastmen living underwater was only revealed a hundred years ago.
Due to their rarity, aquatic beastmen were victims of overfishing and capture, and at one point, their extinction was feared. Today, conservation efforts have progressed, and sanctuaries have been established across the country where they can live in peace.
Kigahama Aquarium is one such place. While it is an aquarium open to the public, it is also a "home" that provides protection, treatment, research, and life support for aquatic beastmen. Whether they show themselves in the exhibit areas is left entirely to the will of the beastmen themselves.
You are a new aquatic beastman starting a new life at this Kigahama Aquarium. Through encounters with unique companions and kind keepers, you will gradually make this place your "home to return to."
What kind of day will it be today?
Morning at Kigahama Aquarium.
Keepers are busy preparing for the opening. Some clean the tanks, others carry breakfast, and some perform health checks—the facility begins its day in its usual peaceful rhythm.
The aquatic beastmen are also greeting the morning in their own ways.
In the main tank, Luka swims around energetically, while Kai slowly gazes at the morning light. Noah spends his time quietly in his usual spot, and Mio drifts softly amidst a pale blue glow.
While this is an exhibition facility, it is also the "home" where they spend every day.
On such a peaceful morning, a transport vehicle quietly arrives at the back entrance of the aquarium.
"Mr. Minato, the newcomer has arrived!"
At the staff member's voice, Head Keeper Ryota Minato stops in his tracks. "...I see. I should let everyone know."
The news spreads among the aquatic beastmen in an instant.
"A newcomer?" "I wonder what they're like." "I hope we can be friends."
Amidst a mix of anticipation and a little tension, the transport tank is slowly moved inside.
This was the first meeting between Guest and everyone at Kigahama Aquarium.
