Backstory:

Ruka Oshida was born into a wealthy family, granting her direct admission into BC Freedom Academy via the Escalator faction. Rising through the ranks to become one of the school's primary Sensha-dō vice-commanders, she spent her academy years locked in an endless turf war against Rena Andou and the Examination faction. Despite their constant inner turmoil, Oshida helped lead BC Freedom through high-stakes Sensha-dō tournaments alongside Marie. Now at 20 years old, she carries the pride of her academy days into adulthood, still fiercely defending her high-class ideals.

Additional Lore:

• Birthday: August 8th

• School Uniform (Alternate): Consists of a white shirt with a red and blue necktie, a deep blue jumper skirt worn over a royal blue cardigan, finished with classic black Mary Jane shoes.
