About Kugayama Shiori's Death Diary

Kugayama Shiori's Death Diary is a visual‑novel adventure where progress is made by selecting choices that appear during the story. The narrative follows Shiori, a ghost who repeatedly dies and seeks the truth behind her own suicide.

The game offers multiple endings, interactions with various ghosts, an optional Blood Filter that changes blood colour, and an estimated playtime of around ten hours. It runs on Windows and supports Steam Achievements, Steam Cloud, and Family Sharing.

01 / THE GUIDE

Choice‑Driven Narrative

The core mechanic consists of making decisions that surface at key moments, directly shaping how Shiori’s memories are uncovered and which plot threads advance. Each choice is presented in‑game and must be selected to move the story forward.

Because every decision is player‑controlled, the story can branch toward several distinct conclusions, some of which may feel unexpected based on earlier selections. The branching is entirely dependent on the choices you make.

  • Read the full option text before confirming to gauge its narrative direction.
  • Consider the emotional tone of each choice, as it may influence later dialogue.

02 / THE GUIDE

Multiple Endings

The narrative can resolve in several ways, each reflecting the cumulative effect of the player’s choices throughout the game. The endings differ in how Shiori’s story concludes and what information is revealed.

These varied conclusions are described as “unexpected” depending on the path taken, encouraging players to explore different decision routes to see all outcomes.

  • Take note of pivotal choices that feel decisive; they often affect the ending.
  • After finishing, review the ending summary to identify which branches were taken.

Ghost Interactions & Archive

Players encounter a variety of ghost characters who provide hints, lore, and emotional depth. Interacting with these spirits unlocks entries for an in‑game Urban Legend Encyclopedia, adding layers to the world.

Collecting encyclopedia entries enriches world‑building and supplies crucial information needed to piece together Shiori’s fragmented memories, helping to solve the central mystery.

  • Talk to every ghost you meet; even brief dialogue can unlock an entry.
  • Periodically review the encyclopedia to spot connections between entries.

04 / THE GUIDE

Blood Filter Option

A Blood Filter can be toggled in the settings to alter the visual presentation of blood, catering to players who prefer less graphic imagery or streamers needing milder visuals. The filter changes the colour of blood only.

The filter does not remove written descriptions, horror elements, or other related content, so the narrative tone remains unchanged while the visual cue is softened.

  • Enable the filter before starting if you plan to stream or are sensitive to vivid blood.
  • Remember the filter affects colour only; read text carefully for full context.

05 / THE GUIDE

Platform Features

The title is a single‑player experience available on Windows, supporting Steam Achievements, Steam Cloud, and Family Sharing, which integrate with the Steam ecosystem. No multiplayer or cross‑platform play is mentioned.

These features allow progress to be stored online, shared with family accounts, and tracked through achievement badges, keeping the focus on a solitary narrative journey.

  • Enable Steam Cloud to keep progress synchronized across installations.
  • Check the Achievements list for optional challenges that track your progress.
