Demons Timeline Hint Guide – Every Case, Identity, Ending

If you’ve started playing Demons’ Timeline and thought “okay… what is actually going on here?”, you’re not alone. This game throws a mountain of accounts, hashtags, hidden identities, timelines, and deduction mechanics at you almost immediately.

And honestly? That’s part of why it’s so good.

The problem is that one missed hashtag or one overlooked comment chain can completely stall your progress for an hour. I learned that the hard way during Chapter 3 when I forgot to bookmark a random comment and had to scroll through half the timeline again.

So this guide is here to make things easier without stripping away what makes the game fun.

Instead of just dumping answers, I’m going to explain how the game expects you to think during investigations, why certain deductions work, and where most players usually get stuck. I’ll also cover all major hashtags, IDs, deductions, and ending requirements in a cleaner way than the in-game flow.

No robotic checklist format. Just a proper walkthrough from someone who spent way too much time staring at Parrotter posts.

Demons Timeline Hint Guide – Every Case, Identity, Ending

Before diving into the chapters, it helps to understand the core systems because the game never explains them clearly enough.

Every investigation is built around five “boxes.”

The first four boxes usually involve:

  • Unlocking Data Files
  • Identifying account owners
  • Finding quotes/posts
  • Connecting timeline evidence

The fifth box is always the final deduction where you answer using hashtags.

The important thing to understand is this:

The game hides critical clues inside comments more often than actual posts.

A lot of players focus too hard on main posts and miss the tiny replies underneath them. Some of the biggest reveals in the game are buried in comment chains with two likes.

Another huge tip:

Bookmark Everything

Seriously.

If a post mentions:

  • pupil colors
  • demons
  • deaths
  • rumors
  • relationships
  • experiments
  • EPORO
  • Gamma Assembly
  • Kasane Namba

…bookmark it immediately.

You’ll revisit old evidence constantly.

Chapter 1 Walkthrough and Answers

Chapter 1 is basically the tutorial, but it quietly introduces almost every important mechanic in the entire game.

You start by accepting the two calls and following the beginner task list.

The game teaches:

  • bookmarking
  • filtering
  • viewing profiles
  • using eye icons
  • identifying main/sub accounts

At first it feels simple, but Chapter 1 already hides important lore about Paradoxes and demon-related deaths.

Data File Passwords

These are straightforward if you read glossary entries carefully.

Data 1 Password
Paradox

This is the term used for bizarre incidents caused by demons.

Data 2 Password
Self-Drop

Internet slang used for suicide.

Chapter 1 Identity Explanations

The first investigation mostly teaches you how to pair:

  • age
  • occupation
  • posting style
  • birthdays
  • relationships

with the correct account.

The easiest example is:

Eporo Official

A company account run by:

  • Hikari Hamamatsu
  • Social Media Manager

The game intentionally makes this one obvious so you understand how “role-based” accounts work.

Meanwhile accounts like Kaitaro Tase are designed to trick you.

The profile says male, but comment chains reveal Kaitaro is actually a woman. That contradiction is the clue.

Owner:

  • Noriko Kurotani
  • Professional Illustrator

That’s the pattern you’ll use for the rest of the game:

  • compare public persona vs hidden truth

The Big Reveal in Chapter 1

The most important deduction is the victim’s death.

Everyone assumes:

  • suicide
  • overwork
  • karoshi

But the correct answer is:

#DiedByPoison

This is the first major sign that the “official story” inside Demons’ Timeline is almost always false.

The colored pupil detail also confirms the case is a true Paradox.

That tiny clue becomes massively important later.

Chapter 2 Gets Way More Complicated

This is where the game stops holding your hand.

Now you’re juggling:

  • A.N.C.L.E.
  • paranormal investigations
  • missing people
  • whistleblowers
  • old incidents
  • deleted accounts
  • urban legends

And this chapter introduces one of the game’s favorite tricks:

Process of Elimination

A lot of identities in Chapter 2 can ONLY be solved by ruling out everyone else.

For example:

Sub Account No.9

The account references:

  • three different people
  • streaming
  • age clues

So the owner has to be the one person NOT mentioned.

That ends up being:

  • Futa Kusuki

The game does this constantly after Chapter 2.

Important Chapter 2 Themes

This chapter introduces:

  • Megumi
  • Kasane Namba
  • Charles Science Museum
  • whistleblowers
  • rollback concepts
  • paranormal communities

Basically every major endgame mystery starts here.

The most important hashtag from this chapter is probably:

#9OClockGhostGirl

You won’t fully understand why until the ending.

Chapter 3 Is Where the Game Turns Dark

Chapter 3 is split into two parts, and honestly this is where Demons’ Timeline becomes genuinely disturbing.

The game moves away from simple murder mystery stuff and starts focusing on:

  • obsession
  • loneliness
  • stalking
  • online identity
  • escapism
  • parasocial behavior

Riki Furuta’s story especially hits hard.

At first you think he’s just another background victim.

Then you slowly realize:

  • he isolated himself
  • abandoned his creative work
  • lost relationships
  • disappeared into VR spaces
  • kept repeating harmful routines for years

The deduction:
#FoodComa

sounds silly initially, but the context behind it is actually depressing.

The game quietly shows a man destroying himself while everyone around him ignores the warning signs.

Chapter 3 Part 2 Explains Arato Furuta

This chapter changes how you view Arato entirely.

Up until now, he mostly feels suspicious.

Then you uncover:

  • scam involvement
  • desperation for money
  • family problems
  • dangerous associations
  • emotional isolation

The hashtag:
#EscapeFromParentsHouse

explains a lot about his motivations.

One thing I really liked here is how the game refuses to make characters purely evil.

Almost everyone feels trapped by something.

Chapter 4 Finally Connects the Bigger Conspiracy

By this point, the game starts linking:

  • media manipulation
  • AI
  • viral trends
  • observer theory
  • online behavior
  • supernatural incidents

And this is where Minorikawa becomes incredibly important.

The “This Eye Ad” detail looks random at first.

It absolutely is not.

That advertisement becomes one of the biggest clues in the entire story because it connects:

  • observation
  • visibility
  • eye contact
  • demon activation

Which ties directly into how abilities work.

The Most Important Lore in Chapter 4

The game quietly reveals that:

  • observation changes reality
  • widespread awareness affects timelines
  • supernatural phenomena can rollback

That leads into:

#SupernaturalRollbackHypothesis

This concept is basically the backbone of the entire plot.

Once enough people observe supernatural events:

  • timelines change
  • memories shift
  • history rewrites itself

That’s why the game constantly emphasizes:

  • social media
  • trends
  • mass attention
  • virality

Parrotter itself becomes dangerous.

Chapter 5 Finally Explains the Ernest Order

This is where the cult storyline fully opens up.

And honestly?
This chapter is chaos in the best way possible.

You’ve got:

  • amnesia powers
  • cult executives
  • fake identities
  • spies
  • supernatural gems
  • EPORO throwaway accounts
  • Fox Demon theories

The funniest part is that some of the most important clues are hidden inside competitive gaming posts.

Classic Demons’ Timeline.

The Fox Demon Mystery

One of the biggest ongoing mysteries is:
Who exactly is the Fox Demon?

The game spends multiple chapters building this figure up through:

  • rumors
  • fake accounts
  • organization ties
  • hidden deals
  • experiments

By now, you’re supposed to realize the Fox Demon isn’t just “a person.”

They’re deeply tied to:

  • Project MG ULTRA VEX-D
  • the Ernest Order
  • Kodama’s experiments
  • Kasane Namba
  • timeline manipulation

This is also where the game becomes openly sci-fi instead of just paranormal mystery.

Chapter 6 Changes Everything

This chapter is basically the “wait… WHAT?” moment.

You suddenly realize:

  • many assumptions were false
  • certain events were fabricated
  • timelines aren’t stable
  • memory manipulation is everywhere

The biggest reveal is probably this:

Nyasuteria’s Ability Is NOT Reading Minds

For most of the game, players assume Nyasuteria reads true intentions.

Wrong.

The final deduction reveals her real power is:

Behavioral Manipulation

That completely recontextualizes earlier chapters.

Especially:

  • synchronized timelines
  • forced actions
  • strange behavior shifts
  • contradictory memories

Once you understand this, earlier scenes suddenly make way more sense.

Yoko and Eleko

Another major reveal is:

#YokoAndEleko

The AI system helped fabricate Paradoxes.

Which is honestly terrifying when you think about it.

The game slowly builds this idea that:

  • AI
  • social platforms
  • observation
  • mass attention

can collectively distort reality itself.

And because Parrotter spreads information so quickly, supernatural effects spiral out of control.

Chapter 7 and the Six Nyasuteria Theories

This is probably my favorite part of the entire game.

Instead of one answer, the game presents six possible identities for Nyasuteria.

And the creepy thing is:
all of them make sense.

Each theory connects her to:

  • experiments
  • school incidents
  • cult activity
  • Kasane Namba
  • urban legends
  • personal relationships

The game intentionally makes reality unstable enough that multiple answers feel plausible.

It’s one of the smartest uses of unreliable timelines I’ve seen in a mystery game.

The True Final Answer Explained

Eventually the game narrows everything down to:

#Kasane_Namba

This answer works because the game isn’t asking:
“Who is Nyasuteria literally?”

It’s asking:
“What change could prevent everything?”

Kasane Namba represents the divergence point.

If synchronization changes her fate:

  • Kodaka avoids the experiment
  • demons never emerge properly
  • timelines stabilize
  • the entire chain reaction collapses

It’s less about identity and more about causality.

And honestly, that final realization hits hard after spending hours untangling the timelines.

All Missable Achievements Explained

Some achievements are easy narrative unlocks, but a few are very missable.

Contrarian Call Block

Decline Nyasuteria’s Disorder call seven times.

Yes, literally just keep rejecting it.

Gaming Urges Mid-Deduction

Minimize the timeline and click the EPORO icon during investigations.

Trendy Cyber Detective

Collect all hashtags in Chapters 1-6.

This one is brutal if you don’t bookmark constantly.

Sheltered Cat Girl’s True Feelings

View every True Intention entry.

Several are extremely easy to miss because they aren’t tied to mandatory deductions.

Best Tips for Completing Demons’ Timeline

After finishing the game, these are the biggest things I’d recommend to new players:

Read Comment Chains Carefully

Some of the most important clues are buried under random replies.

Track Ages Constantly

The game LOVES age deduction logic.

Use Process of Elimination

Especially after Chapter 2.

Bookmark Anything Weird

Even throwaway jokes can become critical evidence later.

Don’t Rush Final Deductions

A lot of the late-game answers only make sense if you think thematically instead of literally.
