Noct Idea — ULT 10 Chart Guide
Juggernaut. · The Hand of Calamity · Run documented
Noct Idea is Juggernaut.'s entry in Arc 4: The Hand of Calamity, and its ULTIMATE 10 chart leans on mirrored edge beams — violet left, pink right — plus translucent triangle and panel walls stacking the midgame. This walkthrough follows one full dive frame by frame, breaks included, straight to the rank B result card.
The Short Version
- ▸Per the song catalog Noct Idea spans MIN 3 · EVO 6 · ULT 10 · FBD 12, and the video confirms the pairing on screen: the CONNECT setup and the result card both carry the level 10 ULTIMATE badge.
- ▸The chart's identity is a pair of mirrored edge beams — violet left, pink right — with translucent triangle and panel walls stacking the midgame and yellow hexagon shields flickering along the lanes.
- ▸Final card: rank B at 089'594'647 — a first clear (HIGH SCORE blank), not a full combo: 94 BREAK, MAX LINK 104, MISS GAUGE 6.
- ▸Honest scope: the catalog publishes no ULT note split for Noct Idea, so the result card's judgement rows — 1,427 judged — are quoted as observed and cannot be cross-validated.
Source Footage
Every fact and screenshot on this page comes from one video: TrappyTheDemon's run of Noct Idea on ULTIMATE 10. The capture is a full-screen game recording with no facecam and the upload has no caption track, so all names and values are quoted from on-screen text. One honest edit note: the capture carries the creator's live-stream badge — an avatar, the channel name and a LIVE marker — fixed to the left edge of every frame. It is recorder overlay, not game UI, and it has been patched out of the stills on this page with an interpolation fill; the video itself is untouched and linked in full.
Honest-scope notes: the upload opens on Noct Idea's jacket card and the CONNECT screen — a SELECT DIFFICULTY rail never appears, so the level 10 ULTIMATE pairing is confirmed by the CONNECT badge and the result card instead. The CONNECT panel displays an "Assist Mode Enabled" tag for this run (the footage doesn't show what assist mode changes), quoted as-is. The result screen counts its score up on screen, so every number quoted here is from the settled card; the upload ends there, with no unlock banner after it. And the catalog publishes no ULT note split for this song, so the result card's judgement rows can't be cross-checked against a note count. Deep-link seconds can land a frame or two off the exact moment; every still on this page was verified individually against the video.
The Chart at a Glance

The video confirms the ULTIMATE 10 chart on screen — the CONNECT setup and the result card both badge the run level 10. Unlike several other Arc 4 tracks, the catalog publishes no note split for the ULT chart, so no note-count cross-check is possible on this page.

How the Chart Unfolds
11 steps · timestamps link back to the videoThe walkthrough below follows the dive in order, from the jacket card to the result card. Each step is one screenshot from the source video, and the credit link under every image jumps straight back to that moment — open it side by side and the chart explains itself.

Meet Noct Idea at level 10
The upload opens on Noct Idea's jacket card — Juggernaut.'s white-capped character over glitch-art neon, a level 10 badge beside it and the CONNECT call on the right. Per the catalog the track ships in four charts: MIN 3 · EVO 6 · ULT 10 · FBD 12; this run takes the ULTIMATE 10.

Set up the dive on the CONNECT screen
The CONNECT panel compares the two sides — STORY against a power of 10 — with the white-haired partner on the left and the jacket's white-cap character grinning on the right. A tag between them reads "Assist Mode Enabled", quoted as-is because the video never explains what assist mode changes. The HUD card top right already names the run: Noct Idea · Juggernaut.

Read the highway before the first note
The dive opens on an empty six-lane highway with the score still at 000'000'000: A S D F key lanes up the middle, a German-labelled side lane (Leer) on the right edge, and the first purple wedge already sliding toward the line. Spend these seconds settling both hands.

Open under the triangle outline
One of the chart's calling cards arrives immediately: a translucent triangular wall drawn over the full width of the highway while the first EXACT judgements tick in at the line. It reads intimidating, but the notes ride the same six lanes — trace the triangle with your eyes once and play through it.

Cross the lavender panel
Early on, translucent lavender panels drop over individual lanes while green wedge notes cross them and EXACT chains stack — three pop in this frame alone. The panels never change the lanes; they only test whether you keep reading the highway underneath.

Expect BREAKs — this run wears them
A sightread is honest about its breaks: mid-chart, the judgement row flashes red BREAK labels between EXACTs and the combo dies, with yellow hexagon shields flickering along the lanes. This run finished with 94 of them on the board — recovery rhythm matters more than a clean first pass.

Climb the cyan wall
Midgame, the chart stacks a tall cyan beam wall down the middle of the highway while a yellow wedge drops across it and EXACT judgements rattle along the line. The wall is a hold-and-read moment: anchor what the wall asks for, then let the rest of the stream ride on free fingers.

Ride the mirrored violet and pink beams
The signature figure: a violet beam runs the left edge while a pink mirror runs the right, EXACT labels popping on both sides at once. One hand owns each edge and the middle lanes stay quiet — when this pair lights up, the chart is asking you to play the frame, not the notes.

Survive to the DIVE CLEARED banner
At the end of the last phrase the banner confirms it: DIVE CLEARED across a darkened highway. In Falsus judges a dive on survival, so the breaks along the way don't take the clear away — they just shape what the result card will look like.

Watch the freeze before the result
After the banner the highway freezes with the score counter parked at 089'594'647, the partner portraits still in their corners and the Noct Idea card top right. It is a short breath between the song and the paperwork — and the last look at the run's final combo trail, 24.

Read the DIVE RESULT card
The card settles at rank B with 089'594'647 points: EXACT 1,094 + 130 across the two tiers, 109 NEAR, 94 BREAK — 1,427 judgements with no catalog note split to check them against. MAX LINK capped at 104, MISS GAUGE at 6, and the IOTA row lists an ASSIST MODE slot. HIGH SCORE stays blank and DIFFERENCE reads the full +089'594'647: a first clear, honestly booked.

FAQ
levels, judgements and the honest scope of this runWhat song is Noct Idea in In Falsus, and who made it?
Noct Idea is a full-release song by Juggernaut. in Arc 4: The Hand of Calamity, added in version 1.0.2c per the song catalog. The video agrees with the catalog on screen: the jacket card, the CONNECT HUD and the result card all read Noct Idea · Juggernaut.
What level is Noct Idea, and is ULT 10 hard?
Per the song catalog: MIN 3, EVO 6, ULT 10 and FBD 12, and the video's level 10 badges confirm the ULTIMATE 10 chart. Whether it feels hard depends on your hands — this page sticks to what the footage shows: a rank B clear with 94 BREAKs along the way, tagged Assist Mode Enabled. For placement against other charts, see the difficulty and hardest-songs pages.
How many notes does the Noct Idea ULT chart have?
The catalog doesn't say. Noct Idea's entry publishes no note split for any chart, so this page cannot cross-check the result card the way other walkthroughs here do. What the card shows is 1,427 judgements as observed — EXACT 1,094 + 130, NEAR 109, BREAK 94 — quoted as-is, unverified against a note count.
How do you unlock Noct Idea?
No unlock gate appears in the footage: the upload opens directly on Noct Idea's jacket card and CONNECT screen, and it ends on the result card with no unlock banner. The catalog lists it as a full-release Arc 4 song since version 1.0.2c. The site's song-unlocks guide walks through how In Falsus actually surfaces tracks — story encounters, difficulty ladders and post-clear unlocks — and is the best map for getting any locked track into your list.
What score or rank did the run get, and is it a full combo?
Rank B at 089'594'647 — and no, it is not a full combo: 94 BREAK, MAX LINK capped at 104 of 1,427 judgements and a MISS GAUGE of 6. It is a first clear, so HIGH SCORE stays blank and DIFFERENCE reads the full +089'594'647. The CONNECT screen also displays an "Assist Mode Enabled" tag, so treat it as a documented casual clear rather than a leaderboard reference.
