B-ko

B-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.
