Maika Hokke is the second oldest of the five Hokke sisters, positioned after Otone and before Yoku, Kanashi, and Utano. Orphaned after their parents, former henchmen for an evil organization, passed away, the sisters endure poverty together. This history drives their shared ambition to achieve "excellent evil," honoring their late father's wish.

She wields fire-based magic, one distinct elemental ability assigned to each sister. Among her siblings, Maika shows heightened awareness of eldest sister Otone's sacrifices in supporting the family through multiple part-time jobs, reflecting her attentiveness to their shared struggles.

Maika actively participates as a member of the Gedou Otome Tai (Heretic Girls Squad), joining her sisters in misguided schemes to commit evil deeds. However, these actions consistently backfire, resulting in positive outcomes that mistakenly earn them a heroic reputation. This pattern of unintended heroism defines the squad's activities.

During an outing to a beach teahouse, Maika makes an extraordinary discovery. Her story unfolds entirely within the core narrative of the sisters' endeavors.
