Numbers are read off the settled result card at t≈187 and its four-channel view at t≈189 (2026-09-21); the top-right song card pins bermei.inazawa feat. 乃花こより, the red FBD 10 badge and SPEED 5.80 on screen. MIN 1 / EVO 4 / ULT 8 match the existing songs-table row; their note counts stay unpublished.
papillon blanc is an Act 2.5 story-progress unlock. The frames below show chart mechanics only — no scenes, dialogue or endings — but the song's existence hints at mid-story progress; very new players may want to defer this page.

The ladder in one panel
The video opens on song select with the whole papillon blanc ladder in one panel — MIN 1, EVO 4, ULT 8 and the red FBD 10 — under an all-songs filter. The jacket hangs uncovered: the player has cleared the song before, and the card prints the proof, FULL LINK 099'966'858 EX+.

FORBIDDEN 10, in the open
The confirm screen names the tier outright: FORBIDDEN — the words behind the FBD abbreviation — beside the red 10 badge. On the right, the guide character あやめ waits with her encounter high score of 000'047'010, the CENTERED result this run will go on to beat.

REFLECT, from zero
The REFLECT screen wipes the score to 000'000'000 and lays the five-card loadout in a row, あやめ on guide duty at the left. These same five cards walk the whole dive with her — and reappear on the result screen at the end of the video.

Wide from the first bar
The dive opens with the field already broad: streams sweep all four main lanes inside the opening seconds, every judgment EXACT, and the clock reads 000'454'699 in PHASE 1. FBD 10 starts wider than most ULT charts ever get.

Hold country begins
A gold and pink hold rail rides the right lane at chain 415, its EXACT landing while cyan hold bars run the left. Holds are the backbone of this chart — keep the four-channel split in mind for step 12: the hold channel alone carries 665 of the 1,447 notes.

The mid-theme field
At chain 727 a wide gold field hold spans the lanes with 050'241'141 on the clock in PHASE 3. The mid-section's grammar repeats without apology — wide field, hold, tap pair — while the encounter gauge quietly climbs to 28,533.

PHASE 5's widest read
The final phase answers with the chart's widest read: a full-width violet field at chain 1,384, four EXACT judgments ringing the line, 095'614'941 banked. One more push and the run walks into its banners.

The banner at full screen
The screen floods violet: PERFECT DIVE — the banner an FBD chart only shows when a run ends with zero NEAR and zero BREAK. All 1,447 notes landed EXACT.

CENTERED pays out
The CENTERED banner sweeps the emptied field: あやめ's encounter surfaces to pay 47,071 points on top of the run. The encounter system counts under the score the whole dive — here it takes its bow.

Frozen at 1,447
The chain counter freezes at 1,447 — MAX LINK, a full chain — with the multiplier at ×5.0 and the encounter bonus at 680.37%. Every chain reading earlier on this page was a checkpoint on the way to this number.

The card that cross-checks
The DIVE RESULT card settles the account: 100'001'420, rank EX+, MAX LINK 1,447, EXACT 1,420 + 27, NEAR 0, BREAK 0 — 1,447 notes, the first published count for this FBD chart. The arithmetic cross-checks: HIGH SCORE 099'966'858 plus DIFFERENCE +000'034'562 lands exactly on the new score, and the timing box reads EARLY 26 / LATE 1.

The four lanes, counted
One click expands the judgment rows into the four-channel split: EXACT 277 tap, 662 hold, 243 field, 238 flick, with the 27 shiny EXACTs split 24 tap and 3 hold — and NEAR and BREAK at zero on every channel. Nearly half of papillon blanc FBD 10 lives in hold notes; that is the fact to know before you dive.

FAQ
Who made papillon blanc?
bermei.inazawa feat. 乃花こより — the credit is printed under the song title on the select screen and again on the top-right song card throughout the dive. The songs table lists the same pair (BPM 138) in its Act 2.5 block, shipped in the 1.0.2c wave.
How many notes does papillon blanc FBD 10 have?
1,447 — EXACT 1,420 + 27, NEAR 0, BREAK 0, summed from a settled PERFECT DIVE card whose MAX LINK 1,447 equals a full chain. The four-channel view agrees channel by channel: 301 tap, 665 hold, 243 field, 238 flick. It is the first published count for this chart; the songs table had carried no FBD note count before this page.
What settings does this run use?
SPEED 5.80 on the six-key FBD chart, with a five-card loadout assembled on the REFLECT screen. No Assist Mode tag appears anywhere at readable resolution — the IOTA particle row drops normally on the result card, and with NEAR 0 and BREAK 0 none would be needed.
Will this page spoil the story?
papillon blanc is an Act 2.5 story-progress unlock, so its existence hints at mid-story progress. Every frame here is a UI screen or gameplay field — no scenes, dialogue or endings — and the meta information above stays chart-only. Very new players may want to wait.
