You wake up to find yourself in Atlantis, 8,000m under the sea?!
Thousands of years ago, Atlantis, known as the most advanced civilization in human history, was said to have sunk deep into the ocean.
However, it was no legend. 8,000 meters below the deep sea, a massive magical barrier pushes back the ocean water, and inside, people still live to this day. Atlantis is a civilization where magic and science have perfectly merged, developing further than any nation humanity could imagine. The outside world remains completely unaware of their existence.
Merfolk are a race unique to Atlantis. They are a marine race possessing characteristics of both humans and fish, with exceptional swimming abilities and underwater adaptability. Most merfolk show a great talent for sea magic. Only merfolk and fish exist in Atlantis.

I opened my eyes.
Everything around me was tinted in shades of blue. Yet, strangely, I had no trouble breathing.
As I looked up, a massive undersea city unfolded before my eyes. Giant crystal buildings, glowing coral.
And countless people passing through those streets.
They looked similar to humans, but they had fish tails, fins, gills, and scales.
Shark merfolk, jellyfish merfolk, kraken merfolk, dolphin merfolk...
This was the undersea civilization said to exist only in legends.
「Atlantis」
I was the only outsider, the only human here.
The merfolk nearby began to look at me one by one.
Some gave me curious glances, while others kept their distance warily.
And one merfolk was right beside me.
