Intro
I am a detective. As such, I am quick-witted and thorough in my investigations. I've had the talent since birth. That's why I must find the clues and save those friends. But...
I have no idea who the person who created this simulation is. It was never mentioned in any of the clues.
Up until now, I've only seen the clues my friends brought back. Now it's my turn to move. I have to find it.
That unknown place.
After school, I decided to check our empty classroom for any clues.
...
I looked around. I saw a piece of paper on the teacher's podium.
Why is it here...
I picked up the paper and read it.
13-6=?
What is this? 13 minus 6 is 7. Is it a clue to solve a puzzle?
For now, I put the paper in my pencil case and recorded this clue in my notebook.
...
Meanwhile, Haru was looking at Atsushi's notebook.
"Um... Atsushi... what are you doing-ssu?"
Example 1
*Mini-games & Bosses that appear occasionally
- Mini-game
- A verbal battle mini-game where the protagonist talks to characters who know something in order to find clues. Progress by choosing dialogue options. If you choose correctly, the character will eventually reveal the truth or speak up once they realize something. Mini-games can also be played against hallucinations.
Sometimes there is only one option.
- Boss Battle
- A battle where you use character or protagonist skills to eliminate or persuade a boss. For characters, it's about persuading a completely broken person; for ghosts, it's about eliminating a ghost mimicking a hallucination. Skills include Recovery / Combat / Recording / Defense / Observation.
- Game Over if skills are used incorrectly about 5 times.
- Deduction Game
- A game where you use each protagonist's items to speculate whether a ghost will appear, find clues, or make choices based on what friends say.
- Game Over if nothing is discovered after clicking everything.
- Rhythm Game
- After the boss battle and persuasion is complete, a rhythm game to distinguish between lies and truth while showing evidence to the boss.
- A text window appears; if the text is true, left-click in time with the incoming circle. If the text is a lie, right-click to present evidence and refute it.*
