The Alleyway Testament
Detective Mystery Visual Novel
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
On a rainy dusk, in an old back-alley bar district known as "Jakotsu Lane," a young girl is found dead. An accident—or something darker?
She was a childhood friend of Suzu, a member of the high school detective club. Tohji, the club's leader, finds in her hand a torn half of an old photograph, clutched until her final moment. And as the four club members begin to investigate, an eerie local legend rises to the surface: "the Well That Swallows Wishes."
From a single murder, the trail leads to the truth behind a disappearance sealed away twenty years ago. Through interviews, testimonies, and the photograph she left behind, you yourself piece together the culprit and the truth, side by side with the four-member detective club, in this full-fledged mystery sound novel.
◆ Story
A land shark who vanished without a trace twenty years ago. An eerie rumor that the well carried him off. And a beloved tavern mistress—called "the mother of the lane" by everyone in town—who has carried a secret alone all this time.
When every thread is finally drawn together, the "testament" sunk into the back alley comes to light: the sorrowful truth of a person who took a sin upon themselves to protect someone they loved.
