About Café 0: The Drowned Mermaid
Café 0: The Drowned Mermaid is a mystery horror visual novel in which you decide whether a girl’s spirit finds peace with her past or haunts the living. With no memory of her life, she wakes in Cafe 0, a mysterious cafe in the middle of nowhere. The waiter Sui serves her only a glass of water, and she realizes she is about to relive the last seven days before her death.
Story and characters
As she retraces those seven days, she encounters Ami, who says she is the girl’s best friend; Tooru, rumored to be her former boyfriend; and Shou, the school doctor. The story explores their connections to her past and how they relate to her death.
The main character is Marin Umino, whose name can be changed. Sui is a calm, mature-looking waiter who can say harsh things without changing his expression. Shou Takizawa, the school doctor, seems to have known Marin since childhood. Tooru Mizutani is her ex-boyfriend, who becomes interested in her again after learning she has lost her memories. Ami Kawase is her best friend, known at school for her beauty and sense of fashion.
Paths and play time
You can choose between three types of main character, each with different costumes. The game has two character paths and one true path, with a secret bonus available after you clear all routes. A playthrough takes about 2–3 hours.
The full version is unvoiced; Japanese voices are included only in the demo and deluxe versions.
