今、誰が為のかがり火へ (Ima, Ta ga Tame no Kagarihi e) is a Touhou Project vocal arrangement by the doujin music circle Yūsoku Satellite (幽閉サテライト), featuring vocals by senya, arrangement by Iceon, lyrics by Kamase Tora, and guitar by neiro. The track originally served as the ending theme for episode 12 of Gensō Mangekyō (幻想万華鏡), a long-running Touhou doujin anime series known for its high-quality animation and musical collaborations with Yūsoku Satellite. The song draws from two source themes from Touhou Eiyashou ~ Imperishable Night, "Touhou Youkai Komachi" (the theme of Komachi Onozuka) and "Tsuki made Todoke, Fushi no Kemuri" (associated with both Kaguya and Fujiwara no Mokou), weaving their melodies into a driving 156 BPM arrangement with senya's characteristic bright, clear vocals. Its title, which translates roughly to "Now, For Whose Sake, to the Bonfire," evokes the fire-and-immortality imagery central to Imperishable Night's narrative. The song joined the maimai DX roster during the Splash PLUS update on March 18, 2021, and is available across all regions including Japan, international, USA, and China. The Master chart, designed by アミノハバキリ at level 12.4, and the Expert chart by 隅田川星人 at level 8.6, offer contrasting challenges that reflect the song's energetic yet melodic character.
