Mémoire — FBD 13

• ▸Mémoire is Zekk's boss encounter for Arc 2.5: Every Moment — its FBD 13 chart shares the highest documented level in the game.
• ▸Both note fields are live from the opening bar; if your cursor hand settles late, the chart compounds the debt for the whole song.
• ▸The crossing-laser hold section is the run's choke point — a dropped hold is a BREAK, which resets combo and damages your Resolve.
• ▸Failing is recoverable: DIVE FAILED ends the run, the result screen still lists your EXACT and BREAK counts, and a retry starts immediately.

Every frame on this page comes from Kyrosol's Mémoire chart view (3:06, spoiler-tagged for Arc 2.5): a straight capture of the playfield with no hand camera. The upload records a complete encounter — including one DIVE FAILED and the retry that follows — which makes it rare documentation of the fail state.

The DIVE FAILED banner (2:52) and the FAILED result screen (3:00) are quoted below — every figure deep-links the creator's timestamp.

Mémoire's catalog entry, straight from the site's song database (community-wiki data, game version 1.0.2c). Levels are documented values from the wiki, not this page's own scoring.

Six frames, one decision each: how the chart opens, where it asks the most, what a failure actually costs, and what the result screen tells you afterwards.

1. 1

   Find it on Music Play

   Mémoire belongs to the Arc 2.5: Every Moment chapter, and its encounter opens as you advance that chapter's story. On the MUSIC PLAY screen, set the difficulty filter to FBD — Zekk's card reads level 13, the shared top of the documented scale. Warm up on the ULT 11 chart of the same track first: the pattern vocabulary is shared, only the density changes.

   

2. 2

   Read two fields from the first bar

   The chart opens with both note fields already live — the keyboard lanes and the mouse-tracked field run in parallel before any laser appears. Use the quietest seconds of the whole song here: fix your cursor hand's resting position early, because every later section assumes it is already where it needs to be.

   

3. 3

   Crossing lasers over holds

   The mid-chart signature: two lasers cross paths while hold notes keep keys pinned underneath. The holds are the priority — releasing early is a BREAK, which resets your combo and drains Resolve in encounters. Trace the lasers with the smallest cursor movement you can afford, and let muscle memory hold the keys.

   

4. 4

   The final density wall

   The closing section stacks taps, flicks and field sweeps into the densest stretch of the chart. Nothing here is new — it is everything from steps 2 and 3 at once. If your health bar reaches this wall with room to spare, do not gamble it back for style; survival lines clear charts, style clears highlight reels.

   

5. 5

   When the dive fails

   Dives carry a health bar, and when it empties the run stops with a DIVE FAILED banner. Nothing is lost: the game rolls you straight into a retry, and the encounter keeps every unlock it already paid out. The frame here is the banner itself — proof that the fail state is a normal part of practicing a chart this high.

   

6. 6

   Read the FAILED result screen

   Even a failed encounter shows the full Encounter Result, EXACT and BREAK counts included. That makes a failure the cheapest diagnostic you get: find where the BREAKs cluster, and that section — not the whole chart — is what your next retry should drill.
