Corona, called Lisa by those closest to her, is the orphaned older twin of Bud. Former students of Geo’s Academy of Magic, the siblings first cross paths with the protagonist after orchestrating a pumpkin-themed prank in Domina’s outskirts—a scheme cut short by the protagonist’s intervention, leading both to become their apprentices.

A natural talent for sorcery sets Corona apart from her brother, her skills honed through wielding a weathered broom inherited from her late father. The twins’ history intertwines with the protagonist’s extended family, anchoring them to a legacy that deepens as they aid in navigating conflicts and pursuing quests critical to unfolding events.

Their journey centers on refining their magical abilities while adapting to the protagonist’s world, their roles evolving in tandem with challenges that test their resilience and camaraderie.
