Cyaegha — FBD 12

• ▸Cyaegha is USAO's Arcaea crossover in the In Falsus track group — FBD 12, one step under the level-13 ceiling.
• ▸Its FBD chart carries 1,698 documented notes (489 taps / 494 holds / 375 field / 340 flicks); the difficulty is sustained overlap, not one impossible pattern.
• ▸Confirm your REFLECT loadout before the dive — encounter cards set the damage you can afford to trade across nearly 1,700 notes.
• ▸The source run cleared at 97,278,998 with full health deep into the final stretch — survival line first, score chasing after.

Frames come from たにし (Tanishy)'s Cyaegha run (2:49) — a DIVE CLEARED record at 97,278,998 whose video title lists the creator's own EX score of 98,411,476. This is a handcam view: the keyboard strip along the bottom edge is the creator's real hands, not part of the game UI. A burned-in Japanese spoiler warning covers the first eight seconds; every frame quoted here sits after it.

The final-gauge frame (2:32) and the CLEARED result (2:46) deep-link the creator's timestamps; the EX score in the title is the creator's best run, not the clear shown here.

Seven frames, one decision each: the loadout you bring, how the chart opens, the two pattern walls, the final gauge, and the result that ends the run.

1. 1

   Find the gate at FBD 12

   USAO's Cyaegha sits in the game's title track group and opens through normal story progression. On MUSIC PLAY its card reads FBD 12 with the sakura-blossom jacket carried over from the Arcaea version. If ULT 10 here feels stable, this is the chart to test whether the FORBIDDEN tier is within reach.

   

2. 2

   Confirm your REFLECT loadout

   Before the dive starts, the REFLECT encounter screen asks you to confirm your card loadout — five slots, and the last calibration point you get. Encounter cards decide your damage and color advantages, and at FBD density you will trade health constantly: bring the setup that keeps damage flowing, not the one that looks best on paper.

   

3. 3

   Opening: taps under a moving field

   The chart opens with keyboard taps on the floor lanes while purple field notes keep the mouse tracking from the first bar. Neither input is hard alone — the cost is running both at once. Settle your cursor hand during these opening bars, because the chorus assumes it never stopped moving.

   

4. 4

   Square holds under a curving laser

   The first real wall: a square purple hold runs while a laser bends across the field. One input has to stay pinned and steady while the other keeps moving — guess which hand is busier and route your fingers around it. Releasing the hold early is a BREAK, and BREAKs at FBD density are how health bars die.

   

5. 5

   The chorus pile-up

   The chorus overlaps tap and hold streams until the judgement line turns into a wall of green EXACT flashes — that green flow is the sign the run is healthy. Cyaegha's FBD chart documents 1,698 notes, and a large share of them land here; if a section is going to break you, it is this one.

   

6. 6

   Manage the final dive gauge

   The source run reaches the last stretch at full health with 98.4 million points already banked. That is the whole lesson of FBD 12: the clear was secured by protecting the gauge through the chorus, not by rescuing it at the end. Play the final bars the way you played the chorus — nothing heroic left to prove.

   

7. 7

   Reading a CLEARED result

   A surviving dive ends on the DIVE CLEARED banner, and the Encounter Result shows the run banked 97,278,998 of the 100,000,000 scale. Clears are survival-based — score above that is ranking territory. The creator's own video title records 98,411,476 for EX on this chart, which is the realistic next target after your first clear.

Tanishy's handcam clear above shows how to survive this chart; Hodor1355's Cyaegha (FBD 12) Perfect Dive (MAX -30)! [In Falsus] (2:50, 47,595 views as of 2026-10-04 — the most-viewed In Falsus capture this site quotes) shows all 1,698 notes judged EXACT. The upload has no caption track this page could quote, so every fact below is screen forensics cross-checked against the song catalog. Overlay disclosure: the capture carries the recorder's keyboard hand-cam plus a key-press panel as two fixed picture-in-picture windows in the top-right corner — recorder overlays, not game UI — measured on the 1600-wide stills at roughly 440×153 (x1162/y183, hand-cam) and 310×235 (x1290/y335, key panel). All five delivered stills are patched with delogo fills at those two rects; on the result card the windows sit over the jacket art, which the patch accordingly covers, while the red FBD 12 badge stays. The video itself is untouched and linked in full.

1. 1

   The loadout behind the Perfect Dive

   The run stages through the same REFLECT screen as the walkthrough above, score at 000'000'000: three cards linked — At The End (1,331/1,331), A Warm Gaze Seeking Others (500/500) and An Aberrant Freedom (1,115/1,115) — with the outer two slots unlinked. The result at the end of this section banks what this loadout dealt: ENCOUNTER RESULT 000'095'551.

   

2. 2

   The opening sail, judged EXACT

   At 002'320'174 the chart's opening triangle panel rides the S lane with three EXACTs posting across the line — the same opening the walkthrough reads at step 3 from Tanishy's run, here at SPEED 4.70 with combo 40 chained and ENCOUNTER SCORE at 1,250. The in-play panel states the terms: Cyaegha, USAO, the red FBD 12 chip.

   

3. 3

   The chorus wall, unbroken

   Mid-chart at 051'340'034 a cyan beam sweeps the F lane for an EXACT while the combo watermark reads 872 — the chorus density the walkthrough's step 5 warns about, taken without a break. ENCOUNTER SCORE has climbed to 44'245 with three of five stars lit, and the run sits in PHASE 3.

   

4. 4

   The banner: PERFECT DIVE

   The highway empties and the hexagonal banner names the run: PERFECT DIVE. With NEAR 0 and BREAK 0 across all 1,698 judgements, the banner subsumes any full-combo claim — this is the site's Perfect Dive definition, on camera, for a chart whose clear was already a gate. The recorder's two overlay windows ride through the banner frame; both are patched here as everywhere in this section.

   

5. 5

   The card: 100'001'668, EX+

   The card settles: SCORE 100'001'668, rank EX+, MAX LINK 1698, and four rows — EXACT 1668 + 30, NEAR 0, BREAK 0 — summing to exactly the documented 1,698 (489 taps + 494 holds + 375 field + 340 flicks). The arithmetic runs to the digit (100'001'668 − 099'883'879 = 117'789), and HIGH SCORE was already printed on the card, so this is a personal best by one hundred seventeen thousand seven hundred eighty-nine, not a first registration. The title's (MAX -30) tag is the card's second EXACT row, 30 — the convention the Greyscale City page documents for this channel's (MAX -31). ENCOUNTER RESULT 000'095'551 posts with a CENTERED chip and four of five stars over the AYAME rail at 688.18 %, and the IOTA strip reads 72 ×2, 70 ×3, 128 ×4, 109 ×1, 42 ×2, 102 ×4, with a seventh cell (113) behind the strip's arrow.

   

Two sources, one chart. Tanishy's handcam stays the page's walkthrough anchor — a survival clear with every pattern read at FBD density — and Hodor1355's run is the ceiling above it: the same 1,698 notes with nothing but EXACTs on the card. Survival first, then the ceiling; both are on camera.
