Hell's 8th Avenue- Miori's Mysterious Notebook

Hell's 8th Avenue- Miori's Mysterious Notebook is a 2D adult adventure for players who like horror settings paired with dark, punishing encounters. It plays out in a moody, unsettling tone that favors tension over comfort.

Story

Miori, a young detective, is sent to investigate a missing person tied to the "Illusory 8th Street," a corrupted place she must purify as she uncovers what happened there.

Gameplay

Players guide Miori through the district's locations, gathering clues and progressing through Quick Time Events that test reaction speed. Falling behind or reacting too slowly during these sequences leads to punishment scenes, tying combat-adjacent tension directly to the game's adult content. Exploration is loosely structured around a sandbox-style map, letting players choose where to investigate next as the mystery unfolds.

Features

• Animated, voiced scenes with hand-drawn 2D art
• Horror-tinged detective premise instead of a straightforward slice-of-life setup
• Quick Time Event mechanic that directly affects story outcomes and scenes
