World Ender — ULT 10
ARC 4: THE HAND OF CALAMITY · SASAKURE.UK × TJ.HANGNEIL · FIRST-ATTEMPT CLEAR
World Ender is sasakure.UK × TJ.hangneil's contribution to Arc 4: The Hand of Calamity — cataloged at MIN 4, EVO 7, ULT 10 and an FBD 13 top tier. This page walks the ULTIMATE 10 chart through TrappyTheDemon's first-attempt sightread: a rank A clear at 094'417'604 with the gauge still holding three points. Of the site's three top-end chart pages, this is the one that ends in DIVE CLEARED — the FBD 14 and FBD 15 walls above it are documented separately.

SOURCE FOOTAGE
Every frame on this page comes from TrappyTheDemon's World Ender ULT 10 sightread (~3 minutes): a full-screen chart capture with no handcam, no facecam and no commentary overlays. The upload records one continuous first playthrough — song detail, the dive from its first beams to the final burst, DIVE CLEARED and the frozen result screen — so every number quoted here is readable in the source.
Because the run is a sightread — a genuine first attempt, as the title declares — the capture shows the chart as a new player meets it, not a perfected route. 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 · v1.0.2cWorld Ender's catalog entry, straight from the site's song database (community-wiki data, game version 1.0.2c). Levels are documented for all four tiers, and the database also records the ULT chart's note split — 313 tap + 529 hold + 503 field + 231 flick = 1,576 notes — which the result screen at the bottom of this page can be checked against. The footage covers the ULT 10 chart only; no FBD 13 capture is quoted here.

Set the target: sasakure.UK × TJ.hangneil, ULTIMATE 10
The song detail screen states the scope before the dive: World Ender by sasakure.UK × TJ.hangneil, jacket art up top, the difficulty rail set to ULTIMATE 10, and a PREVIEW button for a first listen. The catalog files the track under Arc 4: The Hand of Calamity with four tiers — MIN 4, EVO 7, ULT 10, FBD 13 — the top tier sitting just below the FBD 14/15 charts documented on the site's other top-end pages.

The dive opens on diagonals
The first frame of play already has points on the board — 000'736'258 — and the chart's opening statement: purple and cyan beams cutting diagonally across the lanes. Nothing is stacked yet. Use this short runway to set your reading position low, where the beams land, not where they enter.

The signature: a trapezoid wide hold
Around score 008'560'721 the chart states its core idea: a purple trapezoid hold spanning several lanes at once, EXACT judgements landing as it releases. The shape is wide but slow — plant the finger, cover the span, and let the hold do the work while your free hand reads ahead.

Holds pressed over moving streams
The stacked read arrives at score 023'092'519: a long purple wide hold pinned down while white streams run underneath it. One hand stays planted, the other keeps scoring — this is where World Ender separates players who release early from those who trust the hold's tail. Hold through the note, not to it.

The quad-stream wall
The chart's densest idea, at score 042'986'071: four white streams falling side by side with gold hexagon rings spinning at the bottom of the field. The wall doesn't flicker or fake — it asks for even fingers at even spacing. Even pressure beats speed here; the rings mark the judgement line, so read against them.

The mid-chart breather
Past the wall the chart exhales: at score 058'595'874 a single purple stream runs down the centre lane with yellow side streams keeping the edges warm. This is the run's one honest rest — use it to re-grip, check the gauge, and reset your eyes for the closing stretch.

Green wedges, and the first NEARs
At score 074'087'523 the palette shifts: green wedge notes and a yellow guide line cut across the lanes, and the judgement rows show NEAR landing alongside EXACT. In a sightread this is expected — the wedges arrive from new angles late in the chart. They cost judgement points, not the dive.

The final burst
The closing stretch at score 093'768'219: white-gold streams and hexagon rings stacked together, EXACT judgements landing three at a time. It is the densest passage of the capture but a short one — the chart spends its last energy in one burst, and the run on this page rides through it with the gauge intact.

DIVE CLEARED on the first attempt
The banner lands over an emptied playfield: first play, no retry, DIVE CLEARED. The sightread framing matters — this is the chart as a first-time player meets it, and it still clears. ULT 10 demands precision for score, but clearing tolerates mistakes; the gauge is what you spend, not the dive itself.

Read the result screen
The frozen result confirms the run: rank A, 094'417'604, EXACT 1,360 + 99 split across two rows, NEAR 58, BREAK 59, MAX LINK 256 — 1,576 judgements in total, exactly the catalog's ULT note count. MISS GAUGE 3 is the sharpest number on the screen: the run cleared with three points of gauge to spare, and 59 BREAKs is what a sightread at this level looks like.

WORLD ENDER FAQ
SEARCH INTENT · ANSWEREDWho made World Ender, and which arc is it in?
World Ender is credited to sasakure.UK × TJ.hangneil — a joint track — and belongs to Arc 4: The Hand of Calamity, per the site's song database at game version 1.0.2c. The song detail screen at the top of this page shows the pairing on the card before the dive starts.
What levels does World Ender have in In Falsus?
Four tiers, per the catalog: MIN 4, EVO 7, ULT 10 and FBD 13. This page documents the ULTIMATE 10 chart through a verified capture; the FBD 13 chart is in the song database but has no verified capture quoted here. FBD stands for FORBIDDEN — the game's top difficulty family.
How hard is World Ender ULT 10?
Hard enough that a first-attempt sightread still finishes with 59 BREAKs and 58 NEARs — and gentle enough that the same run clears at rank A with 094'417'604. The pressure comes from wide trapezoid holds pressed over moving streams and a four-stream wall; trust the holds' tails, keep your fingers evenly spaced through the wall, and the clear is within reach of a strong level-10 player.
How much margin does the clear have?
Three points: MISS GAUGE 3 on the result screen means the run finished with three points of gauge to spare. The mistake distribution explains why — 59 BREAKs and 58 NEARs across 1,576 judgements is a lot of accuracy lost, and a slightly worse sightread would not have survived it. On a planned run, trimming BREAKs buys the margin back quickly.
What about the FBD 13 chart?
It exists in the song database — MIN 4, EVO 7, ULT 10, FBD 13 is the documented rail — but no capture of it is quoted on this page; everything above covers ULT 10 only. For the tier above it, the FBD 14 and FBD 15 charts, see the hardest-songs guide, where the game's documented walls live.
