KIRETSU — ULT 10 Chart Guide
Laur · The Hand of Calamity · Sightread documented
KIRETSU is Laur's entry in Arc 4: The Hand of Calamity — the jacket reads 綺劣 — and its ULT 10 chart leans on wide purple hold walls plus a mirrored rail pair, one violet and one pink, running the edges of the highway. This walkthrough follows a first-attempt sightread frame by frame, breaks included, straight to the rank A result card.
The Short Version
- ▸Per the song catalog KIRETSU spans MIN 4 · EVO 7 · ULT 10 · FBD 13, and the video's SELECT DIFFICULTY rail and HUD confirm the sightread runs the ULTIMATE 10 chart at SPEED 7.00.
- ▸The ULT chart carries 1,573 notes (337 tap · 584 hold · 382 field · 270 flick), and the video's result card judges exactly that total — the numbers close.
- ▸The chart's identity is wide purple hold walls and a mirrored rail pair — violet left, pink right — with translucent triangle walls stacking the midgame.
- ▸Final card: rank A at 094'597'623 — a first-attempt clear, not a full combo (MAX LINK 372, 43 BREAK). The judgement rows sum to exactly 1,573.
Source Footage
Every fact and screenshot on this page comes from one video: TrappyTheDemon's sightread of KIRETSU on ULTIMATE 10, uploaded 2026-09-13. 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 — avatar, channel name and a LIVE marker — fixed to the left edge of the 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 first ~38 seconds are the song's animated intro before the menu appears — no frame on this page is sampled from it. The CONNECT screen displays an "Assist Mode Enabled" tag for this run (the footage doesn't show what assist mode changes), and the HUD reads SPEED 7.00 on a German key mapping (Umschalt/Leer side lanes). After the result card the upload closes on a "Song Unlocked" banner for KIRETSU — quoted as observed, with broader unlock specifics left to community wikis. 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
catalog data · ULT quoted from the videoLevels below come from the song catalog, and the video confirms the pairing on screen: the SELECT DIFFICULTY rail reads 4 · 7 · 10 · 13 and the HUD card runs KIRETSU · ULTIMATE 10 · SPEED 7.00. The catalog publishes a full note split for the ULT chart — 1,573 notes — and the sightread's result card judges exactly that total. The FBD chart exists at level 13 but is not covered by this footage.

How the Chart Unfolds

Pick KIRETSU at ULTIMATE 10
The SELECT DIFFICULTY rail reads 4 · 7 · 10 · 13 with the purple 10 picked for this run, and the song card names KIRETSU by Laur over the 綺劣 jacket art, illustrated by フリッツ per the on-screen credit. KIRETSU sits in Arc 4: The Hand of Calamity.

Set up the dive on the CONNECT screen
Before the highway drops in, the CONNECT panel toggles between the partners AYAME and LYNN, and this capture displays an "Assist Mode Enabled" tag — quoted as-is, because the video never explains what assist mode changes. The HUD card top-right already shows the run's shape: KIRETSU · ULT 10 · SPEED 7.00.

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, Umschalt and Leer side lanes on the edges (the capture uses a German key mapping). The first purple arrow note is already sliding toward the line — spend the quiet seconds settling both hands.

Open on cyan beams and EXACT chains
KIRETSU opens generous: a cyan lane beam sweeps the left side while EXACT judgements stack into a chain and the combo counter climbs through its first digits. The opening minute rewards keeping the beam hand glued to its lane and letting the chains build.

Combo 6 and climbing — the opening minute is generous · TrappyTheDemon ↗ - 5
Ride the mirrored violet and pink rails
The chart's signature figure arrives early: a violet rail runs the left edge while a pink mirror runs the right, EXACT labels popping along the line as the combo counter passes 126. One hand owns each rail — the middle lanes belong to whatever taps sneak in between.

Expect a BREAK mid-chart
A sightread is honest about its breaks: at this wall the judgement row flashes a red BREAK right next to an EXACT and the combo dies. This run finished with 43 BREAKs on the board — what matters is the recovery rhythm, not a perfect first pass.

Anchor the wide hold wall
The catalog puts holds at the center of this chart — 584 of 1,573 notes — and this frame shows why: a wide purple hold wall stretches across the lanes with an EXACT trail ticking along it. Press the anchor key and keep it down; lifting early to chase the next note is exactly how holds break.

584 of 1,573 notes are holds — anchor and stay down · TrappyTheDemon ↗ - 8
Read the translucent triangle wall
Midgame, the chart stacks a translucent triangular wall over the highway while a yellow burst fires at the left edge and EXACT judgements rattle underneath. Read the wall first, then let the streams ride on whatever fingers are free.

Close on the mirrored rails
The final stretch returns to the mirrored pair — violet and pink running parallel into the last seconds with EXACT judgements on both edges and the score counter at 094'448'866. Nothing new hides in the outro; it asks for stamina, not new patterns.

Read the DIVE RESULT card
The result card settles at rank A with 094'597'623 points under a DIVE CLEARED banner. The judgement rows — 1,310 + 136 EXACT across the two tiers, 84 NEAR, 43 BREAK — sum to exactly the catalog's 1,573 notes, MAX LINK capped at 372 and MISS GAUGE at 13. HIGH SCORE stays blank and DIFFERENCE reads the full +094'597'623: a first clear, honestly booked.

FAQ
levels, note counts and the honest scope of this runWhat song is KIRETSU in In Falsus, and who made it?
KIRETSU is a full-release song by Laur in Arc 4: The Hand of Calamity, added in version 1.0.2c per the song catalog. Its localized Japanese title, 綺劣, is printed vertically on the jacket art, and the video's HUD quotes the same KIRETSU · Laur credit.
What level is KIRETSU, and is ULT 10 hard?
Per the song catalog: MIN 4, EVO 7, ULT 10 and FBD 13, and the video's SELECT DIFFICULTY rail and HUD confirm the ULTIMATE 10 chart. Whether it feels hard depends on your hands — this page sticks to what the footage shows: a first-attempt run cleared at rank A with 43 BREAKs along the way, at SPEED 7.00. For placement against other charts, see the difficulty and hardest-songs pages.
How many notes does the KIRETSU ULT chart have?
1,573. The song catalog splits them into 337 tap, 584 hold, 382 field and 270 flick, and the sightread's result card judges exactly that total — 1,310 + 136 EXACT, 84 NEAR and 43 BREAK add up to 1,573 with nothing missing.
How do you unlock KIRETSU?
No unlock gate appears in the footage: the video opens the menu, selects KIRETSU and dives. The catalog lists it as a full-release Arc 4 song since version 1.0.2c. After the clear, the upload closes on a "Song Unlocked" banner for KIRETSU — quoted as observed; what exactly it unlocks (the FBD chart exists at level 13) is community-wiki territory, not something this footage shows.
What score or rank did the sightread get?
Rank A at 094'597'623 — a first clear, so HIGH SCORE stays blank and DIFFERENCE reads the full +094'597'623. It is not a full combo: MAX LINK capped at 372 of 1,573 notes, with 43 BREAK, 84 NEAR and a MISS GAUGE of 13. The CONNECT screen also displays an "Assist Mode Enabled" tag, so treat it as a documented casual clear rather than a leaderboard reference.
