届かない花束 (Todokanai Hanataba, "The Unreachable Bouquet") is a Hatsune Miku VOCALOID track by the music unit ELECTROCUTICA, added to maimai でらっくす Splash PLUS on April 28, 2021, and carried forward through subsequent DX editions. The song serves as Side Story Essence 3 of 言ノ葉Project (Kotonoha Project) 2nd Season, subtitled "BLACK ROSE", a multi-song narrative arc that weaves together character-driven stories across several maimai original tracks. ELECTROCUTICA is a creative duo centered on composer Treow (作曲) and designer-lyricist Tokitō (時透), with illustration by Shikimi (しきみ) and video production by Yoru Ji (ヨルジ). The song's flavor text (フレーバーテキスト) establishes a dark fantasy setting: a boy who lost his memory is taken in by a church orphanage, where he befriends a girl named Holly. Their peaceful life shatters when the other orphans are corrupted by moonlight and turn demonic. In the chaos, Holly is struck down protecting the boy, and he unknowingly unleashes a fiery magic circle that spreads uncontrollably, forcing him to flee into the night. The "unreachable bouquet" of the title becomes a metaphor for his inability to reach Holly and the life they might have shared. In-game, the Master chart (designed by はっぴー) sits at level 13 with a constant of 13.1 and 659 total notes, featuring a mix of dense Tap sequences, Slide patterns, and scattered Touch notes that mirror the song's rising emotional intensity.

The chart received a level adjustment across versions: Basic was lowered from 4 to 3 as of UNiVERSE PLUS, while Expert was originally rated 10 and Master originally rated 12+ in Splash PLUS through UNiVERSE, before being adjusted to their current values.
