|Japanese name:||シリア 大塚|
Celia Ootsuka is an American "idol" superstar. He/she is shown as someone with amazing strength and is well-known through his/her singing/dancing career as an "idol" as well as a professional wrestler. He/she later squares off against Inaho, whom he/she devastates with his/her jingu and ultimately defeats using wrestling moves, prompting Takeru to fight in Inaho's place.
His/her jingu is an internal-type named "Inverse". Its ability is to "reverse" situations at his/her will. His/her ability is not limited to reversing forces, but could even reverse the will of his/her opponent (as seen when he/she reversed Takeru's will to attack him/her during their battle) and even gave him the ability to change his gender and physical appearance at will including the reason why his eyes have a flower shaped pupil when a girl. He/she possesses the ability to become either male or female including characteristics and emotions. He/she fell in love with Takeru when he showed a cool-looking stance (in her own opinion) to protect Haruko during the match between Venus and Maken-ki. However, it was a normal volleyball match which went extreme after Demitra used her waterbending abilities. Takeru jumps in and accidentally lands on Celia instead of Haruko, much to Himegami's annoyance (because more big breasted girls came into the school). Celia is aiming to become a real woman, and is referred to as an okama. In the anime, she's a girl.
