Shadows of Unknown — ULT 10 Chart Guide
Sad Keyboard Guy feat. vally.exe · The Hand of Calamity · Sightread documented
Shadows of Unknown is Sad Keyboard Guy feat. vally.exe's entry in Arc 4: The Hand of Calamity, and its ULT 10 chart is a wall-to-wall beam piece: curved violet panels, twin pink/violet side walls and yellow flick trios over a candle-lit gothic hall. This walkthrough follows TrappyTheDemon's full capture from the song grid to the result card, with every number read off the screen.
The Short Version
- ▸Per the song catalog Shadows of Unknown spans MIN 4 · EVO 7 · ULT 10 · FBD 12, and the video's SELECT DIFFICULTY rail reads exactly 4 · 7 · 10 · 12 — catalog and capture agree.
- ▸The chart's identity is twin side walls — violet left, hot pink right — under translucent field panels, with yellow flick trios and diagonal slashes over a candle-lit gothic highway (ULT 10 · SPEED 7.00).
- ▸Final card: rank A at 094'529'196 — a first clear (HIGH SCORE blank), not a full combo: MAX LINK 227, 56 BREAK, MISS GAUGE 15.
- ▸Cross-check: the result's judgements sum to 1,366 + 114 + 63 + 56 = 1,599 judged notes — exactly the catalog's ULT split (tap 251 + hold 555 + field 564 + flick 229). Two independent sources, one number.
Source Footage
Every fact and screenshot on this page comes from one video: TrappyTheDemon's sightread of Shadows of Unknown at ULTIMATE 10, a full-screen chart capture with no handcam. The deep link on each step jumps straight to the matching moment.
Honest-scope notes: the capture carries the creator's live-stream badge (a CrabbyTheDemon avatar with PKTR/LIVE chips) on the left edge of every frame — recorder overlay, not game UI — patched out of every still with a small interpolation fill; the video itself is untouched. The song card's partner chip reads "Assist Mode Enabled" and the result lists an empty ASSIST MODE slot; both are quoted as seen. The upload also closes on a SONG UNLOCKED card, which this page does not quote.

Pick Shadows of Unknown at ULTIMATE 10
The upload opens in Music Play with Shadows of Unknown already highlighted: jacket art by Toriki, title and artist underneath, PLAY on the right. The SELECT DIFFICULTY rail lists 4 · 7 · 10 · 12 — matching the catalog's MIN 4 · EVO 7 · ULT 10 · FBD 12 — and the purple 10 is the pick on this run.

Read the song card
Committing pulls up the card: DIFFICULTY ULTIMATE at level 10 and HIGH SCORE "-" — a first attempt. The REFLECT chip on the right shows the NIA partner pair with an "Assist Mode Enabled" line, quoted here as seen. The card then cuts straight to the highway — no CONNECT screen on this upload.

Read the highway before the first note
The dive opens on a zeroed 000'000'000 over a candle-lit gothic hall: four main lanes on A S D F, a purple Umschalt side lane on the left, a pink Leer lane on the right. The HUD card pins the settings — ULT 10 at SPEED 7.00 — and the score sits at zero through a quiet intro.

Ride the opening beam sweep
The first section is one wide violet beam sweeping from lane to lane, striking the line in triple EXACT flashes. The score here reads 000'990'819 — nearly a million points before the verse proper starts.

The quiet intro breaks into notes around the 17th second of the upload · TrappyTheDemon ↗ - 5
Read the curved violet panel
Past the opening, a translucent violet panel curves across the lanes while a fan of white trails fires underneath it. The green splash at the line marks a full EXACT cluster — this panel-plus-fan pairing is the chart's core texture.

Flick the yellow trio
Shadows of Unknown marks its flicks with yellow arrows, and here three arrive in one row across the lanes. Flicks are 229 of the chart's 1,599 notes — read the arrow direction and swipe; hesitation is what turns them into BREAKs.

Chain the yellow diagonals
The mid-section strings yellow diagonal slashes through the stream, each landing as another EXACT — five are visible in this single frame. The center line never cools down; keep the wrists loose and ride it.

Brace for the twin side walls
The climax builds the chart's signature picture: a violet wall on the left, a hot pink wall on the right and a dark center lane between them. The EXACT chain runs straight across the sandwich — the walls are the light show, the center stream is the trap.

Track the translucent panel finale
Late in the chart a blue translucent panel drops over the center while twin cyan beams descend on both sides and a green splash flares at the line. The final stretch alternates panels and bare beams right up to the last note.

Take the DIVE CLEARED banner
The last note lands and the cyan DIVE CLEARED banner slides over the highway. On this upload the final score had already settled at 094'529'196 during the last seconds of play.

Judgements: EXACT 1,366 + EXACT 114 + NEAR 63 + BREAK 56 = 1,599, exactly the catalog's ULT split. MISS GAUGE finished at 15 and the IOTA row shows an empty ASSIST MODE slot. A clear, not a full combo.
