What The Ownership Data Tells You First

Steam’s public achievement statistics for appid 2914150, read October 9, 2026, put the true ending at 24.5% (DONIDEMONARE). Three quarters of buyers never see it. The rows around it give you a difficulty curve no written guide can fake:

Row	Owners	Shipped description
YUNYUN DENPA OTW!	96.0%	“Get your kokoro going doki doki up the wazoo!”
Q † CHANNEL	56.3%	“Oyasumi Qtie!”
HALP!	28.1%	“Just hold on, Qtie-pie. Yunyun’s Denpa to the rescue!”
Yunyun Syndrome	26.3%	“Oopsies.”
DONIDEMONARE	24.5%	“Who’s the happiest weeb in the world? MEEEEEEEEEEE!”
Yunyun Logic	14.9%	“No matter what, I will always love you Qtie.”
Qtie Logic	14.9%	“These are Qtie’s truths.”
Engage Link	9.7%	(blank)

Read the cliff: 56.3% finish the prologue, 28.1% hit the 100% denpa row (HALP!), and 24.5% land DONIDEMONARE. The gap between prologue and denpa max is where most runs die - that is the DENPA grind, not the final boss. And Engage Link at 9.7% tells you that of the people who did get the true ending, roughly six in ten never went back to finish the trend list on that same save.

[Unverified - the mapping between these rows and specific story beats is inferred from names and descriptions, not stated by the developer.]

Preparation: What You Need Before the True Ending

The true ending route is the most fragile sequence in the game. One wrong step - a stat pushed to the cap, a diary read late, accepting instead of rejecting - and that save is finished for true ending content. The endings guide covers the full ending map and the counting problem behind the “39+” figure; this article is exclusively the DONIDEMONARE path.

Prerequisites Checklist

Requirement	How to Check
Fresh save file	Do NOT use a save where DOKIDOKI, HYPE or YUNYUN already crossed 999%
Q † CHANNEL completed	Prologue rhythm charts finished (the row’s own text is “Oyasumi Qtie!”)
Diaries read in the intended order	Save before touching any diary
Timing configured	Automatic audio latency adjustment on; per-song local offset available since Ver. 1.1.0

The save condition is the one that bites. A 999% meter is a bad ending, and the bad ending closes the true ending path on that file - documented in the soft locks guide.

One correction while we are here: this page previously told you to open “Settings > Audio > Automatic Audio-Sync” and set a judgment tolerance. There is no judgment tolerance setting. What actually exists, per the patch record, is automatic audio latency adjustment (in the demo since November 29, 2025) and per-song audio sync, officially called local offset, added in Ver. 1.1.0 (June 30, 2026). The rhythm gameplay guide has the calibration workflow built on those.

The DENPA TRANSMISSION Route: Step by Step

Phase 1: Build DENPA to 100%

DENPA LEVEL is the master gate. It caps at 100% (not 999% - that is the other three meters), and the HALP! row at 28.1% is the achievement attached to reaching it, with the game’s own text reading “Just hold on, Qtie-pie. Yunyun’s Denpa to the rescue!”.

Gain sources, ranked by what they actually are:

Source	What it does	Verified?
Chart clears, per difficulty	First-time clear plus rank, Full Combo and rate bonuses, each independent per difficulty	The bonus categories are the ones the achievement rows describe; the DENPA figure per bonus is not published [Unverified]
Conspiracy trend cards after clears	Feeds trend influence, which feeds denpa	Direction is community-reported; magnitude undocumented
Viewing new endings	Small cumulative denpa	Community-reported [Unverified]

Two patch facts change how you should read any DENPA table, including the one this page used to print:

• Ver. 1.0.7 (Apr 27, 2026): “Reduced the amount of DENPA LEVEL (Denpa Level) required to reach 100%.” The grind got shorter after launch. Any guide quoting a fixed total DENPA number is describing a target that moved.
• Ver. 1.1.0 (Jun 30, 2026): Songs menu sort and search expanded, rhythm start animation skippable, note speed adjustable during play. All three are farming-loop time savings, which is what a DENPA grind actually is.

The old version of this page published a threshold ladder (50% unlocks diaries, 80% preliminary transmission, 90% for Qtie Logic, 100% for HALP!) and a per-bonus payout. Withdrawn. No patch note or store text supports those numbers, and 1.0.7 proves the thresholds themselves were not stable. What survives: measure your own DENPA delta per clear, and treat 100% as the gate.

Phase 2: Read Diary Entries in Order

The diary sequence is the part of the route the community agrees on most and the developer has documented least.

1. Diary 1 - early in the run, on Qtie’s desktop
2. Diary 2 - password reported as “Kurumi Kurusu” [Unverified]
3. Diary 7 - password reported as “0606”, found by dragging Yunyun around the screen until the number appears [Unverified]
4. diary.zip - password reported as “rim de lacent”, the title of Yunyun’s character song

The achievement evidence for the zip is genuinely interesting. Y-unzip! sits at 57.5% ownership with the description “ILLUSION? TEATIME!” - so well over half of players unzip something. Childhood Memz, described as “You found all the pages of Qtie’s diary!”, sits at 16.6%. And Rim de Lacent. - the row named for the character song and the reported zip password - is at 8.8%, in the game’s rarest band.

That spread tells you the real difficulty is not the unzip. Half the player base opens a zip file; under one in ten owns the row named after the password. So either the password route is gated behind something else, or the row triggers on the full diary collection plus the zip. [Unverified - which, exactly, is not documented.]

Phase 3: Trigger Denpa Transmission

At 100% DENPA LEVEL, the transmission becomes available and you send the signal to Qtie. Community guides consistently place the trigger in the Help tab. [Unverified - menu location reported by players, not by the developer.]

The transmission itself is a short cutscene across Qtie’s desktop, after which the endgame phase opens.

Phase 4: Build Conspiracy Influence

The reported requirement for the true ending path is conspiracy influence at a high threshold, commonly quoted as 70%+. The percentage is unverified. What is verifiable is the achievement that sits next to it: Clearly Paranoid Qtie at 9.1% ownership, and the related Yunyun Syndrome row at 26.3% whose entire shipped description is the single word “Oopsies.”

Two ways to get there, both community-reported:

Method A: Natural gameplay. Play charts, keep picking conspiracy cards, let influence build across several clears.

Method B: Intentional failure. Boot two different charts and miss everything so Patootie takes maximum influence - the deliberate-failure route the achievements guide documents for Clearly Paranoid Qtie. Slower to accept psychologically, faster in minutes.

Missing every note on purpose feels like a bug in your own discipline. It is not. This is a rhythm game that rewards deliberate signal corruption, which is also the plot.

Diary Entries: Reading Order and Passwords

The diary layer is the game’s hidden lore system: pages scattered around after milestones, some locked behind passwords.

Item	Reported password	Achievement evidence	Status
Diary pages, all of them	none	Childhood Memz - “You found all the pages of Qtie’s diary!” - 16.6%	Row verified, collection order not documented
Diary 2	Kurumi Kurusu	(none tied)	[Unverified]
Diary 7	0606, via dragging Yunyun	(none tied)	[Unverified]
diary.zip	rim de lacent	Rim de Lacent. - 8.8%; Y-unzip! - 57.5%	Password community-verified, achievement linkage inferred

Why the order matters at all is the shakiest claim on this page. The version I published previously asserted that reading Diary 7 before Diary 2 “corrupts the DONIDEMONARE trigger condition”. I cannot substantiate that, and neither can the patch record. What I can say from the ownership curve: 56.3% finish the prologue, 16.6% find every diary page, and 24.5% get the true ending - meaning a meaningful number of players reach the ending without completing the diary set. The strict-order theory is at best one route among several. [Unverified]

Practical version, which holds regardless: save before each diary interaction. The game’s own bad-ending behaviour proves it tracks state you cannot see, and a corrupt sequence is cheaper to reload than to diagnose.

The Patootie Confrontation

Patootie is the final rhythm battle, and it is the only chart where the failure is narrative rather than a meter penalty.

The specific parameters this page used to publish - a four-minute chart, 300-plus notes, a B-rank minimum, extra notes at high conspiracy influence - are withdrawn as unverified. No patch note describes the fight’s chart data, and the store page does not either. [Unverified]

What is defensible:

1. Treat it like any other chart. The same judgment behaviour, the same latency compensation. Practice on lower difficulties until the pattern is boring.
2. Do not walk in cold. Clear one or two regular charts first so your timing is calibrated to the track, not to the cutscene you just watched.
3. Bring the note speed lever. Ver. 1.1.0 lets you change note speed during play, which is the closest thing this game has to a difficulty knob mid-fight.
4. Bring the offset. If a specific chart fights you, local offset (1.1.0) is per-song, so fixing the boss chart does not break your other twelve.

The Patootie fight is hard mostly because you can see the save-state consequences of losing it. Note density is not the problem; the problem is that you are about to make a decision about a fictional character you have spent hours enabling.

The Final Choice: Accept or Reject

After the fight, Yunyun offers to delete herself from the drive.

Reject (DONIDEMONARE - true ending)

• DONIDEMONARE unlocks, at 24.5% ownership, with the game’s own line: “Who’s the happiest weeb in the world? MEEEEEEEEEEE!”
• The true ending cutscene plays.
• The save becomes the correct base for Engage Link (9.7%), which is the row you clear by going back and finishing the remaining conspiracy trends on that same save.

Accept (alternate ending)

• A different ending plays.
• DONIDEMONARE does not unlock on that run.
• You reload or restart to get the true ending path.

The choice is presented without labels telling you which is “right”. The first time I reached it, I accepted, because it read like the compassionate option. That is the trap and also the point: the game is about whether a signal, once broadcast, gets to keep existing.

Important Notes

Save before the final choice. If you want both endings, keep two slots entering the end of the Patootie fight. I cannot verify whether the game offers a post-choice reload; plan as if it does not.

Engage Link requires the same save. After DONIDEMONARE, finish the remaining conspiracy trends on that file - which is why you should not start a fresh save for trend farming at that stage. Engage Link’s row ships with a blank description, so the condition itself is community-reported. [Unverified]

The true ending does not need 999% on any meter. It needs the opposite: keep DOKIDOKI, HYPE and YUNYUN below the cap on this save, because the cap is a bad ending that locks DONIDEMONARE on that file.

Patch record, October 2026. The route itself has not been restructured. What changed since launch is peripheral but real: Ver. 1.0.7 reduced the DENPA needed for 100%; Ver. 1.0.9 (Jun 1, 2026) unified the NORMAL / HARDCORE GAMER / TRYHARD ratings that were internally identical; Ver. 1.1.0 (Jun 30, 2026) added local offset, mid-play note speed, skippable start animation and judgment distribution; Ver. 1.2.0 (Oct 1, 2026) revised English text throughout; Ver. 1.3.0 (Oct 9, 2026) added five free songs and new DLC. A claim you may see repeated - that an update “added online ranking and new difficulty levels” - describes demo-era features (Monthly Ranking and TRYHARD both landed in the November 29, 2025 demo update), not a post-launch patch.

What The True Ending Actually Means

Interpretation section. Skip it if you want to form your own reading.

The DENPA TRANSMISSION route frames the game as a story about information control and digital identity. Qtie’s desktop is a constructed reality - the conspiracy trends, the denpa signal, Yunyun’s presence on the monitor. The store copy is blunt about it: Yunyun is “a fictional character that loves Qtie”, and “whilst the truth is unknown, most likely, she is just a figment of Qtie’s imagination”.

Rejecting her offer to delete herself is the game’s statement on digital permanence. Once a signal is broadcast, it cannot be un-broadcast. The conspiracy is out there. The only decision left is whether you keep it alive.

That reading is supported by the achievement text better than by any cutscene summary. Yunyun Logic at 14.9% reads “No matter what, I will always love you Qtie.” Qtie Logic at 14.9% reads “These are Qtie’s truths.” Two rows, same ownership rate, two incompatible positions - the attachment runs both directions, and the ending you pick decides whose logic wins. Yunyun Syndrome at 26.3% reading simply “Oopsies.” is the game telling you what the whole condition costs.

Engage Link (9.7%) - finishing every conspiracy after the true ending - is total information saturation: every trend maxed, every channel broadcasting, the digital puzzle closed. It is also the rarest story-adjacent row in the game, which is the joke. You saved the signal, then volunteered to moderate it.

Final Take

The condensed DONIDEMONARE checklist, with claims labelled:

1. Clean save where no meter crossed 999% — verified consequence, documented in the soft locks guide
2. Finish the prologue charts (Q † CHANNEL, 56.3%)
3. Build DENPA LEVEL to 100% (HALP!, 28.1%) - shortest path since Ver. 1.0.7 reduced the requirement
4. Find the diary pages (Childhood Memz, 16.6%); open diary.zip with the reported password “rim de lacent” (Rim de Lacent., 8.8%)
5. Trigger DENPA TRANSMISSION - menu location community-reported
6. Push conspiracy influence high — the “70%” figure is unverified; Clearly Paranoid Qtie (9.1%) is reachable via deliberate full-miss runs
7. Win the Patootie battle - chart parameters unpublished, so treat it as a normal chart with local offset and note speed available
8. Reject the deletion offer — DONIDEMONARE (24.5%)
9. Stay on that save and finish the remaining trends — Engage Link (9.7%)

Save before every step, and treat the acceptance path as a burn.

If you already have DONIDEMONARE and want the rest, the 49 achievements guide has the full ownership table and the multi-run plan, and the endings guide maps every branching point.
