Terminus, 05:00 | Japanese-Style Murder Mystery for 7-14 Players + Host | Printable PDF | 150-180 min

TERMINUS, 05:00 — a Japanese-style murder mystery for 7–14 players and 1 host. 150–180 minutes. Printable PDF.

The night sleeper express Reimei. Out of a northern port town at 22:00, into Tokyo at 05:00. After thirty years of service, tonight is her last run.

One private sleeper carriage has been booked out by the seventy-two-year-old engineer who designed her. Seven people are invited: a daughter, a former colleague, a bereaved daughter, a retired driver, a journalist, an executive, and the conductor working the train tonight. Every one of them is tied to a night thirty years ago.

The only stop is three minutes at 01:58. Nobody got off. Nobody got on.

At 02:45 he was found dead in compartment three, with the mark of a trunk strap on his throat. The train is still moving, and there are two hours and fifteen minutes left.

WHY IT WORKS AS A CLASSROOM ACTIVITY

• Close reading with stakes. Every clue is a document students have to read carefully. Missing one detail changes who they accuse.
• Evidence-based argument. Players make a claim, cite the document it came from, and defend it against the other readings at the table.
• Structured discussion. Fixed phases — reading, discussion, investigation, final discussion, resolution — so the conversation does not drift.
• Scales to a whole class. Seven roles, and up to fourteen players in pairs — so a group of this size can run as one table rather than splitting.
• No preparation beyond printing. The host script is written to be read from the top. No rules to adjudicate, no dice, no components to assemble.

HOW THIS DIFFERS FROM A MURDER MYSTERY PARTY KIT

If you have run a boxed “murder mystery dinner” before, this is a different genre. Please read this before buying.

• The host does not play. They run the game. That is what lets the story hide information the way it does.
• Each player gets a private booklet with a secret only they know, and two goals — one shared with the table, one private.
• The culprit is a player, not the host, with their own goals to pursue.
• Single use. Once a group knows the answer they cannot play it again — but you can run it for new groups as often as you like.

WHAT YOU GET (13 files, 12 of them PDF)

A read-me for everyone, a host script with the full running order and read-aloud text, the evidence set, one private booklet per character, and a plain-text version you can paste into a video call or a shared document.

WHAT YOU NEED

7–14 players plus one host, 150–180 minutes, and either a printer or a shared screen. First-time hosts can run this. Everything prints in black and white on ordinary paper.

CONTENT NOTES

LICENSE

Classroom and club use is fine, including running it for as many groups as you like. Streaming and let’s-plays are allowed, monetized or not. Please do not redistribute or resell the files, claim authorship, or post the solution publicly.

HOW THIS WAS MADE

This scenario was written with the assistance of an AI language model (Claude, by Anthropic), then edited, structured, and consistency-checked by a human before release. The plot, characters, clue structure, and all text were reviewed by the maker.

Ai-Q Labs makes murder mysteries in which all the evidence is text — a corrected page proof, a radio log, a weather record. Check out Ai-Q Labs for the rest of the series.
