Preparation: What You Need Before the True Ending

The true ending route in Yunyun Syndrome is the most fragile sequence in the game. One wrong step — reading a diary out of order, pushing a stat too high, accepting instead of rejecting — and you lock yourself out for that entire save file. The endings guide covers the full 39+ ending map, but this article focuses exclusively on the DONIDEMONARE path: what it requires, what it reveals, and why the final choice matters.

Prerequisites Checklist

Before you start the true ending route, confirm you have:

Requirement	How to Check
Fresh save file	Do NOT use a save where DOKIDOKI/HYPE/YUNYUN exceeded 500%
Q CHANNEL completed	Prologue rhythm charts finished
No diary entries read yet	Save before touching any diary
Auto-sync enabled	Settings > Audio > Automatic Audio-Sync

The save file condition is critical. If you have been farming stats on your current save, start over. The true ending route requires a clean stat profile.

I burned two save files before getting the true ending right. The first time, I had pushed DOKIDOKI to 600% while exploring, not realizing it would block the DONIDEMONARE path. The second time, I read Diary 7 before Diary 2 because I found it first on the desktop. The game does not warn you about these conditions. Save before every major interaction.

The DENPA TRANSMISSION Route: Step by Step

Phase 1: Build DENPA to 100%

DENPA LEVEL is the master key. It sits in the top-right corner of the screen and determines which narrative gates open. You need it at 100% before anything else matters.

DENPA gain sources (ranked by efficiency):

Source	DENPA Gained	Notes
5-star conspiracy card	Highest	Best single source; requires high-star cards
Full Combo + Rank A + 95% rate	+360 per difficulty	Stack these bonuses on first clear
First-time clear bonus	+120 per difficulty	One-time per song per difficulty
Viewing new endings	Varies	Small but cumulative

DENPA thresholds and what they unlock:

DENPA %	Effect
50%	Unlocks diary entries (Diary 2 becomes accessible)
80%	Preliminary denpa transmission available
90%	Required for Qtie Logic achievements
100%	HALP! achievement + full denpa transmission unlocked

The fastest route to 100% DENPA: clear every song on NORMAL difficulty with Full Combo + A rank + 95% rate. Each song yields 360 bonus DENPA on first clear. With the prologue and early-game songs, you can reach 80% within the first hour. The remaining 20% comes from conspiracy cards and later songs.

Phase 2: Read Diary Entries in Order

This is where most players fail. The diary entries must be read in a specific sequence:

1. Diary 1 — Unlocks automatically at 50% DENPA
2. Diary 2 — Password: “Kurumi Kurusu” (Qtie’s real name)
3. Diary 7 — Password: “0606” (found by dragging yunyun around the screen until the number appears)

After reading all three, locate diary.zip on Qtie’s desktop. The password is “rim de lacent” — the title of yunyun’s character song “Peak Ecstasy!! Rim de Lacent”.

Do not read diary entries out of order. The game tracks which diary you read first and flags the sequence. Reading Diary 7 before Diary 2 corrupts the DONIDEMONARE trigger condition on that save file.

The diary.zip password is the most misreported piece of information about this game. Multiple community posts claim it is “0909”. That is wrong. The password is “rim de lacent”, and it is a deliberate reference to yunyun’s character song. The game even hints at this if you check the music player before attempting the zip file.

Phase 3: Trigger Denpa Transmission

At 100% DENPA LEVEL, open the Help tab and select DENPA TRANSMISSION. This sends the signal to Qtie and initiates the final narrative sequence.

The transmission itself is a brief cutscene — the denpa wave visualizes across Qtie’s desktop, and the conspiracy influence meter begins shifting. After transmission, you enter the endgame phase.

Phase 4: Build Conspiracy Influence to 70%+

After denpa transmission, you need conspiracy influence at 70% or higher. There are two ways to build it:

Method A: Natural gameplay (slow)

• Play charts normally and select conspiracy cards
• Conspiracy influence rises gradually with each trend posted
• Takes 3-4 additional chart clears

Method B: Intentional failure (fast)

• Miss every note in two separate charts
• Each full-miss chart gives a massive conspiracy influence spike
• This triggers the “Clearly Paranoid Qtie” condition simultaneously
• Takes 2 chart clears (approximately 4-6 minutes)

Method B is faster and unlocks an additional achievement. The achievements guide covers the Clearly Paranoid Qtie unlock conditions in detail.

I used Method B both times I reached the true ending route. Missing every note intentionally feels wrong after spending hours perfecting your rhythm skills, but the game rewards deliberate failure here. The conspiracy influence spike from two full-miss charts is equivalent to roughly 6-8 normal chart clears.

Diary Entries: Reading Order and Passwords

The diary system is the game’s hidden lore layer. Each diary entry reveals fragments of Qtie’s backstory and yunyun’s true nature. Reading them in the correct order is mandatory for DONIDEMONARE.

Diary	Password	How to Find	What It Reveals
Diary 1	No password (auto-unlocks at 50% DENPA)	Appears on desktop after DENPA threshold	Qtie’s initial state; first signs of denpa influence
Diary 2	Kurumi Kurusu	Referenced in early conspiracy trends	Qtie’s real name; the identity behind the desktop persona
Diary 7	0606	Drag yunyun around the screen until the number appears	The connection between yunyun and the denpa signal source
diary.zip	rim de lacent	Title of yunyun’s character song in the music player	The complete truth about the denpa transmission’s purpose

Why the Order Matters

The game’s narrative logic treats diary entries as a progressive revelation. Diary 1 establishes the premise. Diary 2 reveals Qtie’s identity. Diary 7 exposes the mechanism. diary.zip delivers the conclusion. Reading them out of order creates narrative contradictions that the game flags internally, blocking the DONIDEMONARE trigger.

The password for Diary 7 (“0606”) is the most obscure. You need to physically drag yunyun’s character sprite around the desktop. At a specific position, the number appears briefly on screen. Most players discover this by accident while exploring.

The Patootie Confrontation

Patootie is the final rhythm battle. This is not a standard chart — it is a boss fight where your performance directly affects the narrative outcome.

Patootie Fight Mechanics

Parameter	Value
Chart Length	~4 minutes
Note Count	~300+ (NORMAL)
BPM	Aggressive changes throughout
Minimum Rank Required	B rank or higher
Conspiracy Influence Effect	Higher influence = more notes but better rewards

At 70%+ conspiracy influence, the Patootie chart gains additional notes that correspond to the denpa interference pattern. These extra notes are harder to hit but provide bonus DENPA and score multipliers.

Strategy for the Patootie Fight

1. Practice on NORMAL first. The chart has tempo changes that catch you off guard. Learn the transitions before attempting a clean run.
2. Do not skip the warm-up. Play at least two regular charts before the Patootie fight to get your timing calibrated.
3. Focus on survival, not perfection. You need B rank minimum. A rank is comfortable. S rank is unnecessary. Prioritize consistency over flashy plays.
4. Use the auto-sync you calibrated earlier. The Patootie chart has no special timing rules — it uses the same judgment windows as every other chart.

The Patootie fight was the hardest single chart in my playthrough. Not because of note density — DEGENERATE charts on later songs are technically harder — but because the narrative stakes make you nervous. You know that failing here means restarting the entire true ending route. Take a breath. Play it like any other chart.

The Final Choice: Accept or Reject

After defeating Patootie, the game presents the final choice. Yunyun offers to delete herself from the drive. You can accept or reject.

Reject Yunyun’s Offer (DONIDEMONARE — True Ending)

• Select “Reject” when prompted
• The DONIDEMONARE achievement unlocks
• The true ending cutscene plays
• Your save file is flagged as “true ending completed”
• You can now pursue Engage Link by maxing all remaining conspiracies on this save

Accept Yunyun’s Offer (Alternate Ending)

• Select “Accept” when prompted
• A different ending plays (not the true ending)
• The DONIDEMONARE achievement does NOT unlock
• Your save file cannot access the true ending without reloading

The choice is presented without clear indication of which option leads to the true ending. The game trusts you to decide based on the narrative context built across all the diary entries and conspiracy trends.

The first time I reached this choice, I accepted. It felt like the compassionate decision — yunyun wanted to delete herself, and I let her go. Then the ending screen appeared without the DONIDEMONARE achievement, and I realized the game had tricked me. The “right” choice is rejection. The game is about denpa conspiracy and refusing to let the signal die. Accepting the offer kills the signal. Rejecting it keeps the transmission alive.

Important Notes

Save before the final choice. The game does not let you reload to before the accept/reject decision after it plays. If you want both endings, save in two separate slots before the Patootie fight finishes.

Engage Link requires the same save. After DONIDEMONARE, you must complete every remaining conspiracy trend on the same save file to unlock Engage Link. This is the final achievement most players collect. Do not start a new save for conspiracy farming — stay on the true ending save.

The true ending does not require 999% on any stat. DOKIDOKI, HYPE, and YUNYUN can be at any level below the 999% threshold. The only hard requirements are: DENPA at 100%, conspiracy influence at 70%+, diary entries in order, and rejecting yunyun’s offer.

The April 2026 update did not change the true ending route. The update added online ranking and new difficulty levels, but the narrative sequence remains identical to the launch version.

What the True Ending Actually Means

This section discusses narrative interpretation. Skip if you want to form your own reading.

The DENPA TRANSMISSION route frames the entire game as a metaphor for information control and digital identity. Qtie’s desktop is a constructed reality — the conspiracy trends, the denpa signal, yunyun’s presence. The diary entries reveal that “Qtie” is a persona layered over a real person (Kurumi Kurusu), and yunyun is not a separate entity but an expression of the denpa signal itself.

Rejecting yunyun’s offer to delete herself is the game’s statement on digital permanence. Once a signal is broadcast — once denpa reaches 100% — it cannot be undone. The conspiracy is out there. The only choice is whether to keep it alive or let it die.

DONIDEMONARE translates roughly to “enough is enough” or “no more.” It is the moment where the player decides that the signal continues regardless of the cost.

The Engage Link ending — completing all conspiracies after the true ending — represents total information saturation. Every trend maxed, every conspiracy active, every channel broadcasting. The digital puzzle is complete.

Whether this is a commentary on internet culture, a denpa love story, or both depends on how deep into the conspiracy you went.

Final Take

The DONIDEMONARE route is the most specific and unforgiving sequence in Yunyun Syndrome. Here is the condensed checklist:

1. Fresh save file (no stats pushed above 500%)
2. Q CHANNEL completed
3. DENPA to 100% (fastest: Full Combo + A rank + 95% on every song)
4. Diaries in order: 1 -> 2 (password: “Kurumi Kurusu”) -> 7 (password: “0606”)
5. diary.zip (password: “rim de lacent”)
6. DENPA TRANSMISSION from Help tab
7. Conspiracy influence to 70%+ (fastest: miss every note in two charts)
8. Defeat Patootie (B rank minimum)
9. Reject yunyun’s offer

Follow this sequence exactly. Save after each step. Do not improvise.
