Mermaid

The Mermaid is an NPC in the game Minimalist Art Club, found in one of the side rooms off the main Gallery on the second floor. According to the Mermaid, she is paid a wage to simply sit in her tank and take photos with tourists passing through the Gallery. A job that, while it helps her get by, results in extreme boredom over time.

According to the sign in front of her tank, the Mermaid is in fact a hybrid between a Mermaid and a Siren, obtained on a planet called Elaskand 3. She is apparently very dangerous, a fact that does not seem to be reflected in any interactions the player can have with her.

If the player obtains the Waterproof Cellphone and brings it to the Mermaid, she will give the player a Key Piece in thanks for bringing her an object to alleviate her boredom. This is necessary to obtain Minimalist Art Club's Secret ending.
