Birthday Blues, Part 1


Hello, Sailor Mini Moon

"The Pure Heart Stolen! Usagi's Biggest Crisis" was the 13th episode of the third season of the Sailor Moon anime, and the 102nd episode overall. It first aired in Japan on July 16, 1994. The English dub title for the episode is "Birthday Blues, Part 2", and it first aired in North America on June 28, 2000.


Usagi is told to come to the Tokyo Tower and is determined to retake her brooch and save Tuxedo Mask. Just when they think Usagi's Heart Crystal is as pure as one of the three Pure Hearts, it is corrected.


Usagi is horrified by both her brooch being stolen by Kaolinite and Tuxedo Mask frozen by Cenicienta. The other Sailor Senshi arrive, but Kaolinite and Cenicienta leave with the brooch and Tuxedo Mask with the former telling Usagi to come to Tokyo Tower.

Usagi hitches a ride with Haruka and Michiru to the tower telling them about sacrificing one to save the other.

Arriving at the Tokyo Tower, Usagi allows her heart crystal to be stolen by Cenicienta hoping to trade her life for Tuxedo Mask's. But, Sailors Uranus and Neptune arrive and stop it and learn, that Usagi's heart crystal isn't pure enough to produce a treasure. Uranus returns the heart crystal to Usagi.

Kaolinite announces her intentions to kill Usagi having learned that she is Sailor Moon. All hope seems lost, when the other Senshi come with Sailor Venus using a Sailor Moon-like appearance to convince Kaolinite otherwise.

Kaolinite throws the brooch away and leaves Cenicienta to battle the Sailor Senshi while she fights Sailor Uranus and Neptune. Sailor Venus uses techniques to fool Cenicienta along with breaking off her hand. Luna races the brooch back to Usagi who transforms into Sailor Moon. She then immediately destroys Cenicienta with the Moon Spiral Heart Attack, and unfreezes Tuxedo Mask, then spends a moment with him alone.


Changes From the Manga

  • Kaolinite died when she turned into a Daimon and was destroyed by Super Sailor Moon. She only died once and never returned.
  • Sailor Venus never disguised herself as Sailor Moon, though she did pretend to be the reincarnation of Princess Serenity when she was Sailor V.

Dub Changes

  • The Korean dub erased the Japanese words used on the signs when Sailor Venus showed up disguised as Sailor Moon. This practice was used during the whole series.

First Appearances


  • This is the last episode that mentions the Disguise Pen being used.
  • This is the second time Tuxedo Mask was captured by the enemy. The first time was back in season one when he was captured by the Dark Kingdom
