Mistress 9 is a Daimon from Tau Nebula; an evil spirit who serves Pharaoh 90. This is the original depiction of the character created by Naoko Takeuchi. She is an evil female entity from "Tau Star System" who has come to Earth to help open a gateway for her master, Pharaoh 90. She possesses Hotaru Tomoe's body (to varying degrees of intensity).


She has long black hair like rapunzel and dark eyes. She wears a blue sleeveless top with white beads and a long white dress. She also wears earrings with white beads.



The Death Busters are frequently striving to awaken Mistress Nine deep within her host, Hotaru. When the Death Busters first visited Professor Tomoe (as he was reconstructing his fifteen-year-old daughter Hotaru's body), one of the objects they gave him was an egg that contained Mistress 9. He implanted it within Hotaru's body, but the consequence of this action was Hotaru's permanent frail physical state. She occasionally suffers from seizures that are soothed at first by an amulet given to her by Tomoe (he tells her it is an heirloom, but it is more likely a fragment of the Tau Crystal) and later by the Silver Crystal. When Chibiusa shows it to Hotaru, Mistress 9 becomes aware of it and later grabs it from Chibiusa, sending her into a comatose state.

When Mistress 9 overpowers Hotaru's mind and body, it becomes that of a grown woman. Her facial features are maniacal and there is little resemblance to the girl whose body she has taken over. Her purpose is to create an opening to the Tau Ceti Star System so that Pharaoh 90 can access and assimilate himself into Earth.

Once all her allies have been killed and is confronted by Sailor Moon and the Outer Senshi, her plan begins. Mugen Gakuen itself is ripped apart, throwing the unconscious bodies of Mercury, Mars, Venus and Jupiter into the air (they come to rest on a structure that Kaorinite previously used for divination). She then attempts to escape Hotaru's body (meaning that her power will be able to flow freely) but is surprised to find that the soul of Hotaru still exists within the body and is inhibiting her from leaving it. Nonetheless, she swallows the souls of the Guardian Senshi where upon Hotaru retrieves their Heart Crystals along with that of Chibiusa and escapes to return them to their owners. While she is doing this, Mistress 9 is able to leave Hotaru's body, ripping it apart in the process. Her true form is of a gigantic monster with a ghoulish head and an indistinct body.

She absorbs all of the Senshi's attacks and opens the door for Pharaoh 90, who begins to smother the planet. Mistress 9 is assimilated into the lava (which presumably is Pharaoh 90) and just when all seems lost, the spirit of Sailor Saturn herself rises from it. When she sets her Silence Glaive down into the ground on its sharp sickle point, both Pharaoh 90 and Mistress 9 experience intensely vast agony, weakness, and paralysis. To finish the job once and for all, Sailor Saturn uses her immensely powerful and destructive Death Reborn Revolution attack to drain the last of their remaining strength and they both rise into the sky to escape back to Tau System. Sailor Saturn follows them and commands Sailor Pluto to seal the door for eternity. Pluto does this and assures that Mistress 9 and Pharaoh 90 can never reach Earth again.


After being possessed by Germatoid, Professor Tomoe chose his daughter, Hotaru Tomoe, to be the host of Mistress 9. She needed Pure Heart Crystal s to increase her power, which is why Kaorinite and the members of Witches 5 continued seeking out Pure Hearts. She demanded him to collect Pure Hearts after the Holy Grail was obtained by Sailor Moon, which Tomoe first interpreted as collecting valuable hearts (by Mimete's standards) and then focused shortly on collecting large quantities of them. As her power grew, she gained more control over Hotaru's body, which culminated when Kaolinite helped Mistress 9 absorb Chibiusa'sPure Heart. This caused the true awakening of Mistress 9, causing Hotaru's body to transform by growing older, letting her hair grow out extremely long, and her outfit changing into a sleek black and blue dress. Saying that Kaolinite served her purpose and is not needed anymore, Mistress 9 killed her with a bolt of electricity. Sailor Uranus and Sailor Neptune attacked Mistress 9, but Sailor Moon jumped in front of her and took the attack to protect Hotaru. Mistress 9 threatened to kill Sailor Uranus and Sailor Neptune unless Sailor Moon gave her the Holy Grail

Professor Tomoe, now free of Germatoid's control, appeared, and Hotaru appeared to regain control and ask for the Holy Grail to return to normal. However, Sailors Uraunus and Neptune sensed a trap set up by Mistress 9, and warned Sailor Moon not to give it away. However, sensing Hotaru was still there she and Professor Tomoe gave her the Grail. The trick worked and she used it to summon Pharaoh 90, destroying the Holy Grail in the process. However, she was attacked by Pharaoh 90, but was protected by Sailor Moon and Professor Tomoe. Hotaru ultimately overpowered Mistress 9 with strong memories of Chibiusa and Tomoe and awakening the spirit of Sailor Saturn herself deep within Hotaru, and she was destroyed.


After Professor Tomoe and Kaorinite become Master Pharaoh 90'sminions, he gives them the Daimon egg of Mistress 9, his partner in a past life, and orders them to implant it in a vessel. In order to fulfill his lifelong dream of creating a superior life form, Professor Tomoe implants the egg into the body of his daughter Hotaru. Ever since then, Hotaru suffered from violent seizures probably caused by Mistress 9 residing deep within her body. Detecting the vast powers and presence of the Silver Crystal coming closer, Mistress 9 began to get stronger, starting to take control of Hotaru, even as Hotaru tried to fight back. She had momentarily taken control of Hotaru and was amused when she heard Kaolinite desired to be Pharaoh 90's devoted partner and sycophant.

However she quickly disappeared and Hotaru, coming back to her senses, was seized with a severe headache and collapsed. When Chibiusa arrived to try and save Hotaru from the Outer Senshi, who were going to kill Hotaru to prevent Sailor Saturn from awakening, Mistress 9 managed to fully emerge from within a weakened Hotaru and grabbed Chibiusa's Prism Heart Compact, knowing the Silver Crystal was inside. Doing so had caused Chibiusa to fall into a comatose state, stealing her soul as well. The Outer Senshi realized that this new enemy was not Sailor Saturn, because she emerged without the talismans activating, and she called to her master, Pharaoh 90, that she had finally awakened.

As Mistress 9 took note of how uncomfortable her current body was, Professor Tomoe and Kaolinite arrived to greet her. Tomoe expressed his joy and his part in her arrival by implanting the Daimon egg in Hotaru years ago when Hotaru was hurt in the lab accident that took the life of Hotaru's mother. Mistress 9 heard someonespeak, acknowledging what Tomoe explained. Mistress 9 ordered Kaolinite to destroy the Senshi by any means, and she would not tolerate another failure. She went to the top of Mugen Academy to communicate with Pharaoh 90, and caused the entire structure to be covered and guarded by thorn vines with purple roses. She presented the Silver Crystal to him, to which he felt its power. But Mistress 9 heard Hotaru's voice, saying it's protected by a beautiful soul. Mistress 9 removed the Silver Crystal from the pendant and swallowed it. She became amazed when the Silver Crystal began increasing its power within her, but was immediately resisted by Hotaru, who protected Chibiusa's soul.

She took further control, causing Hotaru's consciousness to be ripped apart and fade away. She then willingly merged with her master. To gain more power, she took the souls of the Inner Senshi. However, Hotaru fled her body, taking Chibiusa, and the Senshi's souls, as well as the Silver Crystal, out of Mistress 9 and Hotaru's body was destroyed, and Mistress 9 took on her true form. The Senshi battled Mistress 9 and a revived Sailor Chibi Moon arrived, causing damage to the Daimon. Chibi Moon gained her Super form and she and Super Sailor Moon combined their attack in an attempt to destroy Mistress 9. She survived the attack and began to merge with Pharaoh 90. All the Inner Senshi and Tuxedo Masktried to destroy them, but they resisted the attack, and opened the portal to the Tau Star System, increasing their power, and breaking the barrier around the Omega Area, allowing Pharaoh 90 to spread through the world.

Sailor Saturn awoke from within them and committed lethal damage to them as she prepared to end the world. Mistress 9 perished with Pharaoh 90 when they were sent back to the Tau system by Sailor Saturn before dying.

  • In the anime, Mistress 9's human appearance is her true form.
  • In the Nakayoshi Character Poll for the Infinity arc, Mistress 9 was listed at the 23rd most popular character.
  • In the original anime, she had sought refuge inside 8-year-old Hotaru and gradually took control of her by feeding on pure hearts until she was fully re-awoken after swallowing Chibiusa's pure heart crystal. She then tricked Sailor Moon into handing over the Holy Grail willingly and presented it to Pharaoh 90.
  • She never had a true form that looked similar to Daimon in the 90s anime.
  • It is interesting of note that when Mistress 9 aged Hotaru's body to that of an adult woman after gaining control over her, she bore a striking resemblance to her mother, Keiko. As it was Hotaru's actual body and not an assumed Daimon form of Mistress 9, this indicates that Hotaru will grow to strongly resemble her mother when she reaches adulthood.
