Biko Daitokuji

Bko is a rich affluent young woman who is a serious megalomaniac. She has a onesided rivalry with Ako who mostly ignores her and wonders why she even tries to fight her. Bko is unrelentingly jealous of Ako039s ability to be likeable and carefree and also of her deep friendship with Cko. Bko immediately becomes interested in Cko when she and Ako transfer to their new school. Her interest turns into obsession though she chalks up her newfound crush on Cko as simply wanting to be her best friend instead. Through flashback we learn that Bko was a horrid ugly little girl with a mean streak and always picked on Cko much in the way that someone with a unknowing childish crush might tease someone they liked. Not much has changed as she got older save for her looks and Bko039s desire to be friends with Cko turns into actual desire though she probably is not all too aware of this. She is rather intelligent as she has the abilities to design and construct several mecha and mechanical suits for fighting but Bko039s scheming nature and mania for Cko makes her appear to simply be a crazed stalker with a crush and too much time and money on her hands. Bko says that she will take on the role as the quotbad guyquot to Ako039s quotheroquot status since people see her as a villain anyway. She is not necessarily a bad person Bko just does a lot of bad things.
