DescriptionA-ko, a red-haired girl who seems to be near invulnerable with superhuman speed and strength, is the heroine of the series and lives in Graviton City, Japan. A-ko is usually friendly and cheerful. She tries to lead a normal life, and spends a lot of time on clothes, a part-time job and romance in the sequels. However, she does have a fiery temper. She also has a large appetite and a tendency to oversleep on school days. She and C-ko are both transfer students to Graviton High, but wear their former school's sailor-style uniform for most of the film | |

DescriptionB-ko is well known at Graviton High as the daughter of a local industrial tycoon. A genius, she is seen living luxuriously, taking a limo to school and having several admiring henchmen in her class. Although seemingly calm and poised in public, deferring to her teachers' authority, B-ko is haughty and goes to great lengths to get what she wants. Her desire to steal C-ko's affection away from A-ko develops into an obsession. She devotes all her resources to this goal, but defeating A-ko seems more important to her than actually winning C-ko's approval. | |

DescriptionC-ko Kotobuki is A-ko's best friend and has depended on her since they met in kindergarten. Though the same age as the other two girls, C-ko is less mature. In the Japanese original, she frequently refers to herself in the third person. Though normally extremely cheerful, C-ko cries easily when facing hardship. She enjoys cooking, but the results are inedible. In the first installment of the series, C-ko is revealed to be the Fourth Princess of the Fifth Queen of the Lepton Kingdom of Alpha Cygni, an all-female race of extraterrestrials. She crash-landed on Earth when she was an infant, and the Lepton Kingdom has been searching for her ever since. However, C-ko is uninterested in her unearthly ancestry and wants to remain on Earth with A-ko. | |
