"Bad Harmony" is the fourth episode of Sailor Moon S and the eighty sixth episode in the series overall. The episode aired June 15, 2000 on Cartoon Network's Toonami.


Serena goes to Darien's house to give him some cookies, but trips, causing the cookies to fall. Serena asks each of the girls to help her study, but they don't take her seriously. Meanwhile Amara and Michelle (who are clearly Sailor Uranus and Sailor Neptune) want to find the three Pure Hearts before the Heart Snatchers do.

Serena discovers Michelle to be an expert violinist and artist, and wants to play the violin for Darien. When an attempt at playing the violin proves unsuccessful, Michelle and Amara take her to a restaurant for some ice cream, and Michelle gives her two tickets for her and Darien to go to a concert. A violinist at the concert is Kaorinite's next target, and she implants a Daimon pod in his violin.

Amy, Raye, Lita, and Mina also go to the concert. While the violinist is performing, his violin transforms into a Daimon Heart Snatcher named Octave, who puts the audience to sleep and steals the violinist's Pure Heart. The girls all transform and fight Octave, who attacks using her screechy voice.

After she is attacked by Tuxedo Mask, Sailor Uranus and Sailor Neptune arrive, but refuse to work together with the Sailor Scouts. However, Sailor Moon saves Sailor Neptune from Octave's attack, and Sailor Uranus uses World Shaking on Octave before Sailor Moon destroys her with Moon Spiral Heart Attack. Sailor Uranus and Sailor Neptune return the Pure Heart to the violinist, as it is not one of the three crystals.



  • First and last appearance of Daimon Octave.
  • An animation error occurs in the scene when the Sailor Scouts arrive to fight. Sailor Moon's "odango jewels" are missing or may have been uncolored.


Raye: "(slaps Serena, who is not paying attention and drooling over Darien, on top of her head) You're not paying attention!"
Serena: "I'm listening with my ears, and ogling with my eyes, ok?!"
Raye: "Turn around, and face the stage!"
Audience: "Shhh!!"
