Nine Tails, Ten Nights

A Seoul murder case

Nine Tails, Ten Nights is a choice-driven interactive story for PC set in modern Seoul. Baek Yeoul is a gumiho, a nine-tailed fox from Korean folklore, who has vowed to harm no human for 1,000 days so she can become human. Ten days before that vow ends, a series of murders makes her a suspect. You investigate the case through dialogue, limited-action searches and decisions that shape the story.

Yeoul works as an investigator on Seoul’s Hidden Side, settling disputes among spirits while passing as human and keeping her hunger in check. The case also follows Kang Doyun, a detective looking for his missing partner, and Han Somi, who is seeking the truth about her sister’s death. Each character has different information: Yeoul knows the Hidden Side’s rules, Doyun can access investigation records, and Somi has footage her sister left behind.
