Serena is Usagi's older twin sister who goes to the same school as her. She has higher grades than Usagi and she is the legendary guardian who is known as Sailor Star.
What if Tuxedo Mask didn't fall in love with Usagi? What if Usagi wasn't Chibiusa...
Chika Tsukino is Chibiserena's younger sister. She's 5 years old. She can be nice, but she's mean if she doesn't like people or if anyone is mean. She's also know as Sailor Earth. Artemis P is the same as Luna P. Chika doesn't go anywhere without it. During her journey with her sister, she starts missing her dad.
Likes: Artemis P, Being around Serena, fun, waterfall, Luna and Artemis, Sailor Star, her sister, Tuxedo Mask, playing with Mamoru Chiba.
Dislikes: People being mean to Chibiserena, not having Artemis P with her, Sailor Moon (formerly) the black moon.
In Earth, she's Chika Tsukino. In Silver Millennium, she's Chika Small Lady Serenity.
Chibiserena is Lady Serenity.( Chibiusa is now Chibiserena since Usagi will be her middle name)
