Koan

How Koan joined the Tourney
Koan was the most conceited and most ambitious of the Spectre Sisters, as well as the most developed in the anime. She was constantly making up her face, bemoaning her looks, teasing her elder sister Calaveras, and shopping as a human for new cosmetics and clothes. Koan's greatest dream was to become the Queen of Crystal Tokyo - with a King Rubeus by her side. Much of this fantasy was fueled by her belief that Rubeus loved her like she loved him, a fantasy which Rubeus did nothing to discourage.

As the first sister to appear, Koan became the one most engaged in finding Chibiusa (as opposed to simply capturing Crystal Points, which she only did once). This was a job that Rubeus often trusted her with, and the more she failed, the more determined she became to kill Chibiusa and win Rubeus' love.

Koan, did not have the same respect for her elder sisters as Berthier, who always referred to Calaveras and Petz as "oneesama" (御姉様; elder sister). Despite this, she seemed to truly love her sisters, as shown through her determination to purify the others as well.

Koan's missions led her to unsuccessfully infiltrate the Hikawa Shrine no less than three times, which made her reluctant to go there. Nevertheless, she willingly went to the shrine in episode 70 to kill Chibiusa, even after Rubeus displayed his complete distaste for her. She almost succeeded, even with the interference of Sailor Mars and Yuuichirou Kumada, because Koan avoided Mars' attacks and ended up breaking the Senshi's ankle. Only the interference of Tuxedo Mask allowed Koan to be defeated, and when she was beaten again, Rubeus came and publicly humiliated her, telling her she was no longer welcome and giving her one last present to use on the shrine and the Senshi - a bomb which would also kill her in the process.

Distraught at Rubeus's rejection of her, Koan was willing to use the device but was stopped by the other Sailor Senshi. Angry that she failed even at killing herself, Koan tearfully attacked the Senshi and was almost taken down by a knee thrust from Sailor Jupiter. Sailor Mars, however, took the hit for her after seeing that Koan had only been used by Rubeus and asked Sailor Moon to heal the evil in her. Koan was subsequently turned into a human and would later help her other sisters become human as well.

Upon the time of the Second Tourney, Koan learned of her powers returning and she must fight an Espada named Aaroniero Arruruerie.
