“What's that rhythm-game track with a girl on the cover and a secret final-boss vibe? Glorious Lady, maybe?”
It's Grievous Lady by Team Grimoire vs Laur, a hidden boss track in Arcaea. You can forget the spelling but still remember the feeling of opening the wrong door and meeting the final boss. It doesn't merely stick in your head; it stages an incident there.
Finding the original only creates a new problem. There is a six-minute official arrangement, a different long version, a remix by co-composer Laur and a fan piano performance. How many health bars does this boss have?
Why the original hits so hard
The track arrived on November 3, 2017. Its in-game edit runs about two minutes and twenty seconds at 210 BPM. Hidden in the Vicious Labyrinth pack, it could interrupt a playthrough of Axium Crisis through a special transition when the conditions were met. Instead of selecting a boss battle, you were ambushed mid-song. The associated character is Tairitsu. Fast percussion and a surprisingly elegant melody make it feel both dangerous and grand. [1]
Five versions worth your time
- Original game edit — the concentrated 2017 encounter and the best starting point.
- nothing is but what is not — an approximately six-minute arrangement from the official 2019 soundtrack. Phase two.
- UMBRA MORTIS long version — a different extended interpretation on Team Grimoire's album.
- Laur Remix — the co-composer reworks his own track in 2024. New Game Plus, composer edition.
- Phyxinon's piano cover — a fan performance in which ten fingers attempt to survive a boss fight.
A good listening route is original → six-minute version → Laur Remix → UMBRA MORTIS → piano. Recover the memory first, then discover how much further the composition can go.
Is that an official popularity ranking?
No. YouTube hosts artist uploads, automated audio tracks and fan performances from different years and channels. Views on five selected videos do not establish the overall popularity of each version. This is a listening guide, not a verified top five.
The 2019 Memories of Conflict tracklist includes both the original and the six-minute arrangement. [2] Laur's official remix video appeared in November 2024. [3] The piano performance is a cover, not an official remix. [4]
For the initial shock, choose the original. For a grand second phase, choose the six-minute arrangement. For a rematch, choose Laur Remix. You came back for one forgotten song, and now the boss has followed you out of the game.
