First Appearance

Parallel Sailor Moon

Kousagi Tsukino is a character who only appears in the Materials Collection's side story, and she is the second daughter of Usagi Tsukino and Mamoru Chiba.


Kousagi is a Sailor Senshi, though no name is given to her. She hangs out with the daughters of the other Senshi: Mina Aino, Mako Kino, Rei Jr, and Ami Jr.. Unfortunately for her, they only hang out with her because their mothers are friends. She is largely disliked by her friends as she eats a lot and puts out everyone's enthusiasm. Mina, Mako, Rei and Ami often run away from her and make her do things for them. After sensing the planet is in danger, Kousagi's friends realise they need to save her.

They attend a cooking class taught by Michiru, Haruka, and Setsuna. Kousagi is nicknamed Chibi by her older sister, Chibiusa. Kousagi has the same hair style as her sister but instead of two odango, she has four. Her Senshi outfit is adorned with bunny heads. She does not really have any attacks, but to transform, she yells out "Parallel Moon Power, Make Up" using an unnamed compact.


Kousagi has bright pink hair tied up into four rabbit ear shaped oranges and curly bunches and blue eyes. Her civilian outfit consists of a short summer dress with ball shaped patterns on it and dark coloured sandals.

Her Sailor fuku is similar to Sailor Moon's except she has two rings on her sleeves, gloves, belt and boots. She has rabbit heads on her bow, hair clips, hair covers, tiara and brooch.  Her colour scheme has yet to be verified. 


Kousagi appears in the side story Parallel Sailor Moon where she is seen chasing Ami Jr, Rei Jr, Mako and Mina. They complain about having to let her stay with them but promptly leave her behind. Before deciding who would look after Kousagi with a game of rock, paper, scissors. They hear Kousagi scream that there's a pink cat on her. They force her to bring the cat despite it being one of her biggest fears and make her carry their bags. After running off again, Kousagi is left trying to catch up, then, the four girls see a bright light that they believe is a UFO or meteorite. They then suddenly feel the earth is in danger in their own ways and also realise they have to protect Kousagi. Kousagi is then hit by something and finds herself with the pink cat as a human. The cat tells her that she must transform and save the planet, and that she can call the other girls her underlings. Kousagi agrees and meets up with Ami, Rei, Mina and Mako who are now also Sailor Senshi. The bright light is revealed to be a herd of rabbits and Kousagi summons a horde of cats to become a giant Lynx and eat the rabbits. The five girls then wake up an annoyed Setsuna, Haruka and Michiruand Kousagi questions whether it was all a dream or not.

Powers and abilities

As a Sailor senshi, Kousagi can summon cats with the attack: Kitty-cats, Kitty-cats, become one humongo Lynx!! She appears to hold a weapon that looks like the Moon stick but it is never mentioned or properly shown.


  • Kousagi's name means "Child Rabbit of the Moon."
  • Because no name is given to her in her Senshi form, fans often refer to her as Parallel Sailor Moon or Sailor Usagi.
  • Her character seems to be sort of a "what if" situation, as Sailor Pluto and the Sailor Quartet clearly state that the Queen of the Moon can only have one child, which in this case, is Chibiusa, but that was also only a strong theory.
  • As the second daughter of Mamoru and Usagi she looks almost the same as Chibiusa.
  • Her blood type is O.
