Primeval Texture, FBD 10 in full
Primeval Texture by くるぶっこちゃん gets the site's cleanest FBD record yet: a CONNECT deck screen, a full clear at rank A, and a result card that sums to 928 notes — the first published count for this chart. Twelve frames take you from deck to DIVE CLEARED.

Numbers are read off the settled result card at t≈158 (2026-09-20); the select card pins the artist くるぶっこちゃん and the FORBIDDEN 10 badge on screen. MIN 2 / EVO 5 / ULT 8 follow the existing songs-table row; their note counts stay unpublished.
Primeval Texture is a mid-story progression unlock. Frames below show chart mechanics only, but the song's existence hints at story progress — new players may want to defer this page.
Deck, jacket, opening
- 1
The deck on display
The video opens on the CONNECT screen: the glitched Primeval Texture jacket, a red FORBIDDEN 10 badge, a six-card deck row and the guide character. It is the clearest deck reference on any of the site's FBD pages — and the same six cards reappear on the result screen.

The opening claim
A wide purple field and a pink BREAK open the chart at 003'551'480. FBD 10 is the tier where wide fields stop being events and become the background rhythm of the chart.

Cellular walls
The background's red cellular art — the "primeval texture" itself — frames a chain of 189 over twin EXACT taps. The jacket art and the field art are one system here.

The long purple
A long purple field crosses the lanes at 025'158'470 with a BREAK beside EXACT. Holds like this one pay out chain — but only if the taps inside the hold are also EXACT.

The wide violet
A wide violet field spans the field at 036'167'449. On a five-finger read this is one motion; the chart's trick is that it never sends just one.

Gold hex country
Gold hexagonal hold markers ring the lanes under a NEAR and EXACT at 049'807'131. This is the middle theme: holds on the rails, taps in the middle, and the cellular walls pressing in.

Streams with a green fan
A green burst fires over the left rail at 056'085'451 as the chart settles into its streaming middle. Nothing here is exotic — the difficulty is that it never stops.

Bracketed
Violet and pink side fields bracket yellow center taps at 065'656'333. Reads like this — outside and inside at once — are the chart's signature demand.

Late push
A green fan slab and tap pairs carry the chain at 076'678'826. The final third adds density without changing the vocabulary — the same three ideas, faster.

The last field
A violet and cyan field carries the final stretch at 087'152'017. The chart ends exactly the way it opened — wide, purple, and honest about it.

Cleared
The DIVE CLEARED banner sweeps the empty field. No miss-gauge drama here: the run never let BREAKs stack, which is what a first FBD clear is supposed to look like.

The card that counts
The result card sums it: 090'733'492, rank A, MAX LINK 102, EXACT 733 + 87, NEAR 44, BREAK 64 — 928 notes, the first published count for this FBD chart anywhere.

FAQ
Who made Primeval Texture?
くるぶっこちゃん (Kurubukkochan) — the artist name is printed on the song card on screen. The song sits in the Act 2.5 block of the songs table and shipped in the 1.0.2c wave.
How many notes does Primeval Texture FBD 10 have?
928 — EXACT 733 + 87, NEAR 44, BREAK 64, summed from a settled rank-A result card. It is the first published count for this chart; the songs table had carried no FBD note count before this page.
What does the CONNECT deck screen show?
A six-card deck row, the guide character, and the red FORBIDDEN 10 badge beside the glitched jacket. The deck screen is worth pausing on if you are learning how decks are assembled before a dive — the same cards return on the result screen.
Will this page spoil the story?
No scenes, dialogue or endings appear in any frame — every image is a UI screen or gameplay field. The song is a mid-story unlock, so its existence hints at progress through Act 2.5; very new players may want to wait.
