Fubuki Sakuragasaki, a 14-15-year-old female student, possesses exceptional arcade gaming abilities. Her childhood gift of "Passion Panties" from legendary gamer Arashi unlocked near-magical powers, enabling a winged magical girl transformation with a sword. This form heightens her reflexes and grants signature techniques like "Ichigeki-de-Clear" and "Ten Chi Jin." Initially dependent on the panties, a pivotal defeat by rival Chizuru Jyumonji—wielder of black Passion Panties—in the Japan BAG Tournament finals drove Fubuki to hone her innate skills. Through rigorous training, she overcame her reliance on magic and narrowly defeated Chizuru by 10 points in a rematch, showcasing her evolved mastery.

Her journey intertwines with the Gyulassic Group, an organization seeking world domination through gaming tournaments. During the World BAG Tournament, Fubuki confronted the group's leader—her mechanized, presumed-deceased father, altered after a missile incident. Forced to reconcile familial bonds with her mission, she witnessed her father depart on a journey afterward, leaving her in her mother Ruriko's care.

Key relationships shaped Fubuki's growth: classmate Hanako Kokobunji offered steadfast support, while mentor Mr. Mystery—a former champion—guided her development. Battles against Gyulassic operatives like rhythm-specialist Melody Honey and velociraptor Raptor tested her abilities. Evolving from a rivalry-driven competitor, Fubuki matured into a gamer prioritizing fun and camaraderie, collaborating with former adversaries. Beyond her core story, she appears in *Keroro Gunso* manga cameos.
