, フーカ・レヴェントン

During their childhood, Fuka and Rinne were both residents at the same orphanage. After leaving the orphanage, Fuka found work as a freelancer to support herself. One year before the events of ViVid Strike!, the relationship between Fuka and Rinne deteriorated due to an incident in which Fuka expressed sympathy for Lyra Caprice, a striker opponent who had been defeated by Rinne and criticized in a post-match interview.
