Outwardly cheerful and energetic
To her classmates and teachers, Madoka appears to be a model student—excelling in both academics and athletics. Behind this polished exterior, however, lies an obsessive devotion to her older brother Kazuto. His sudden death shattered her composure, driving her into a fixated state and igniting fierce hostility toward Kirihime Natsuno. Beyond her combat prowess with the oversized multipurpose cleaver 'Maguro Kui,' she also has a talent for cooking fiercely spicy curry.
