Geranium is a maimai original song produced by Osanzi, with vocals by 藍月なくる (Nakuru Aitsuki). It arrived as part of the BUDDiES PLUS update on August 2, 2024, tied to the Heaven Area 7 (天界ちほー7) event. Players originally unlocked the track by accumulating 150 km of total play distance, a challenge format that became a hallmark of the Heaven Area series. The song is steeped in the narrative lore of the Heaven Area. Its flavor text features Cocabiel, a character from the area's storyline, who proclaims the destruction of a realm where "only boring lilies bloom" and vows to adorn the desolation that remains with white geraniums. This theatrical monologue foreshadows lyrics that weave together philosophical questions about love, identity, meaning, and emptiness, all anchored by the recurring image of white geraniums (白く咲くゼラニウム) blossoming in a void. Musically, Geranium is a driving electronic vocal track at 150 BPM, blending Osanzi's crisp production style with Nakuru Aitsuki's expressive delivery. The song's accompanying movie was created by あるし and Kazeto. On the charting side, the Master chart (level 13+, constant 13.7) was co-designed by はっぴー and サファ太, a pairing recognized for intricate and engaging layouts, while the Expert chart (level 10+, constant 10.6) was handled by Jack.
