エンジェル ドリーム (Angel Dream) is a Namco original song that originated in Taiko no Tatsujin 10, where it debuted as a hidden track accessible only through a specific command input at the title screen, a quirk that made it something of a discovery among arcade-goers of the era. Its bright, angelic pop melody stands in thematic opposition to The Carnivorous Carnival, a demon-themed counterpart that appeared alongside it in the same Taiko release. The song proved enduringly popular within the Taiko no Tatsujin community, ranking third in the Namco Original category of the series' 10th-anniversary "Memories Song Survey." Composed and arranged by Keiichi Okabe, best known for his work on the Nier series soundtrack, with lyrics and vocals by Yoko Takamitsu and guitar by Yoshinori Goto, the track carries an uplifting, breezy energy built around a steady 180 BPM. The lyrics paint a gentle fantasy of angels descending on a sunny day, holding hands, sharing courage, and stepping forward into the future. The chorus centers on a simple, singable "La la la" refrain that echoes the song's dreamy, carefree tone. エンジェル ドリーム was added to maimai DX as part of the CiRCLE edition on September 26, 2025, categorized under GAME & VARIETY. Its maimai debut features a full DX chart set across Basic through Master, with the Expert chart designed by Luxizhel and the Master chart by Safata (サファ太). An UTAGE (宴) chart, bearing the designer note "目と目を合わせて舞を分け合おう" ("Let's meet eyes and share the dance"), was added later in December 2025. The jacket art used in maimai is adapted from the Idolmaster Cinderella Girls Starlight Stage design with color modifications.
