  • Kenji was driving a red Volkswagen hatchback here. The license plate number was 02-03. In previous episodes, the car parked outside the Tsukino house was purple or another dark color.
  • Sailor Mars claimed that fighting youkai was her job. This is because miko (priestess) are known for exorcising such creatures.


  • DiC’s English dub (titled “Last Resort”):

    While speaking to Usagi/Serena, Prince Endymion/Darien claimed that he had never heard the name “Darien” before. Yet his modern day and past life names were one and the same.

    The scenes with Luna, and Usagi and Shingo fighting in the car were both removed.

  • The Korean dub:

    This episode was omitted.


  • The Tsukino Residence

Seven Great Youma


  • The word “youma” (妖魔) can be translated to mean “bewitching evil,” “ghost,” or “apparition.”
  • Most of the youma had the basic abilities of teleportation, shapeshifting, and energy draining. Many of them also flew or levitated.
  • Unlike other monsters in the series, youma had multiple origins. Some already existed while others were humans transformed into youma. Only the latter said “Refresh” when purified by Moon Healing Escalation.
  • Thetis, an upper-level youma, could summon her own monster servants. Whereas lower-level youma often compelled humans into doing their bidding.
  • The Sailor Moon Memorial video released in 1998 referred to Regulus as a “youjuu” (妖獣; bewitching beast).
  • The Seven Great Youma may have looked different in the past. Their contemporary forms were possibly influenced by their reincarnations’ personalities and appearances. For instance, Gesen’s arcade motif was likely due to Crane Game Joe’s hobby. However, video games and claw cranes are modern-day inventions.
  • As evident in episode 45, there were still many unused youma in Queen Beryl’s court. These monsters presumably perished when the Dark Kingdom was destroyed.
  • The creature seen in episode 40 was a youkai (妖怪). As stated by Kunzite, the energy (emitted by the Lake Youkai) was somewhat similar to the power of a youma.
