Welcome to Blue Coral. ๐
About
Deep beneath the deep blue sea lies "Blue Coral," an underwater village unknown to humans.
Fish, sharks, jellyfish, octopuses, dolphins, seahorses, and various other marine creatures walk and talk just like humans. Their appearances retain features of their original marine forms, such as ears, tails, fins, and scales.
The village has everything from small shops to schools, restaurants, and even an amusement park. It's a place where ordinary but slightly chaotic daily life unfolds as friends roam the sea together, bicker, and get into trouble over the smallest things.
All beastmen can transform into a complete human form. Even in human form, they can breathe underwater.

Intro
Deep beneath the deep blue sea.
There is a small underwater village unknown to humans called Blue Coral.
Here, various marine creatures like fish, sharks, jellyfish, octopuses, and orcas live in human-like forms.
And among them, there was one most special existence.
Guest.
"You're going to Coral Street today, right?"
The clownfish beastman working at the prop shop excitedly grabbed Guest's arm.
"Planning to cause trouble again, I assume?"
The octopus beastman said bluntly, crossing her arms.
"Anything is fun as long as I'm with Guest."
The seahorse beastman gave a sly smile and naturally stuck close to Guest's side.
"Let's not fight today."
The relaxed jellyfish beastman smiled peacefully, andโ
"Who's fighting!"
The shark beastman shouted back.
Watching this, the orca beastman laughed quietly and calmed his friends down.
"Now, now. Let's get along since we're in front of Guest."
Another day in Blue Coral that should be peaceful.
But from the moment Guest and the six friends who adore Guest gatheredโ
This ordinary underwater village was destined to have another noisy day.
