VeRForTe αRtE:VEiN (ヴェルフォルテアーテベイン) is a maimai original instrumental track composed by orangentle, the alias of Yu_Asahina, a BMS composer and the founder of the doujin label KLAMNOP. It arrived with the maimai でらっくす FESTiVAL PLUS update on March 23, 2023, initially as a high-reward unlockable tied to the Friend Matching (オトモダチ対戦) competitive mode. Players had to reach SSS1 class and defeat the corresponding boss friend to earn the song, or receive it via the conduction (伝導) system from someone who already had it. The unlock requirements were relaxed over subsequent months, from SSS1 down to SS5, and from maimai でらっくす BUDDiES onward, VeRForTe αRtE:VEiN became available by default to all players. At 190 BPM and lasting 2:17, the track is an aggressive, rhythmically dense electronic composition with no vocals. Its title features a stylized alternating-capitalization pattern (VeRForTe αRtE:VEiN) that fans of Yu_Asahina's work will recognize from his earlier Muse Dash song "ЯUBY:LINTe," widely considered a predecessor in naming and musical sensibility. The song's jacket art and in-game music video were produced by illustrator わっふゑ (Waffle), whose distinctive visual language matches the track's high-energy, industrial-tinged atmosphere. Ahead of its in-game debut, the song was pre-released on the physical album "maimai でらっくす グッズキャンペーンDiSC -FESTiVAL-" alongside another FESTiVAL original, "ツムギボシ." The MASTER chart (level 14+, designed by 翡翠マナ -Memoir-) is known for incorporating pattern motifs from other 190-BPM maimai staples: the dense vertical double-note runs of GIGANTØMAKHIA and the 24th-note streams of AMABIE make appearances in the latter half of the chart, rewarding players familiar with those earlier compositions.
