What lurks in the aquarium is blue terror and the mystery of the abyss--[Who is the traitor?]

"Aquariums Don't Dance" is a free horror game that was developed and completed by the creator Toudou, who hates horror, over a period of eight years.

It achieved 100,000 downloads in just two days after its release in February 2024, and as of June 2025, has exceeded 600,000 downloads, making it a popular title that is currently attracting attention.
The series has been turned into a drama CD, a comic book series, various merchandise, and other collaborative projects, and its popularity is still growing!

That day, a young girl named Suze and her best friend Lulu were visiting the Bianca Aquarium and were enjoying a guided tour accompanied by the director's wife, Chris, as a special perk of their premium tickets.
Along the way, Suze and the others suddenly lose sight of Lulu and start searching for her inside the aquarium, but suddenly find themselves lost in a creepy world that is completely different to the aquarium they were in earlier.
While Suze is exploring a terrifying aquarium where aquatic monsters are attacking her, a woman in military uniform and carrying a sword named Retro appears before her.
Retro is rude to Suze, but she is also looking for another girl named Kitty.
Will Suze be able to find her best friend and escape from the aquarium?
