A-ko, the depth of my vexation is beyond your comprehension!
~ B-ko


B-ko (B子) or Biko Daitokuji (大徳寺 美子 Daitokuji Biko) 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 very calm and poised in public, and always 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. As A-ko appears to be the child of Superman and Wonder Woman, it could be argued that B-ko is intended to be the daughter of Tony Stark; her father sports a moustache of the exact same style as Stark's.
