Song Connections / Remixes


  • 煉獄のエルフェリア is the final song of MAP DX-7 of the Qprogue event of beatmania IIDX 21 SPADA, and the final overall song of the event. It could be unlocked from April 30th, 2014 through September 17th, 2014.
  • 煉獄のエルフェリア is the only beatmania IIDX 21 SPADA song with boss overlays to have an exclusive generic video.
    • Modified versions of this generic video were later used for songs from the Chrono Seeker event in beatmania IIDX 22 PENDUAL.
    • In beatmania IIDX 30 RESIDENT, this generic video was replaced with SPADA HARDCORE.
    • As of August 22nd, 2023, the generic video has been reverted back to the original one.
  • The intro of 煉獄のエルフェリア's video shows some characters from ALBA -黎明- and DARK LEGACY in their Q-pro versions.
  • The boss in 煉獄のエルフェリア's overlays is Ferira, transformed into a monster by an enemy sorcerer.
    • Ferira will progressively shift to her successive forms if you reach a high enough EX Score before certain points of the song. Failing to meet the requirement will make the boss keep her form until the end of the song.
    • In her first form, when you miss a note, she will shoot an explosive energy ball from her mouth to attack the Q-pro avatar.
      • The boss will shift to her second form halfway throughout the song.
        • In her second form, when you miss a note, she will attack the Q-pro avatar with lightning magic.
      • The boss will shift to her third form before the end of the song. Clearing the song after triggering this form shows a secret ending where Ferira is brought back to her normal state (otherwise, she will not survive).
        • Her evil human form is named Madou Knight Ferira.
        • In her third form, when you miss a note, her evil human form will appear and strike the Q-pro avatar with her sword.
  • When 煉獄のエルフェリア is played on beatmania IIDX, the arcade LED marquee displayed the song title as "ERFERIA".
    • As of February 25th, 2015 in beatmania IIDX 22 PENDUAL, the LED marquee now displays "ELFERIA OF PURGATORY" instead.
  • In the Japan iTunes version of the beatmania IIDX 21 SPADA Original Soundtrack Vol. 2 Selection album, 煉獄のエルフェリア is known as Elferia of Purgatory.
  • 煉獄のエルフェリア is available in beatmania IIDX INFINITAS as part of beatmania IIDX INFINITAS Music Pack vol.6 (beatmania IIDX INFINITAS 楽曲パック vol.6).
