Regina
A girl in a black dress who presents herself as the daughter of King Selfishness and serves as second-in-command of the Selfishness Trio. She's best known for her bratty demeanor—spoiled, vain, and openly selfish, treating everyone around her as servants. Fans often note her habit of threatening to tattle to her father whenever the trio won't obey her, throwing tantrums like a younger sibling despite her leadership role.
Regina's defining ability lets her force anyone to give birth to a Selfishness, regardless of whether they actually harbor any selfish qualities themselves. She uses this power freely and without apparent remorse.
Beyond the cruelty, there's something almost playful about her—she enjoys dragging Mana away from classes and responsibilities to goof around, seemingly viewing the world as her personal playground. She's openly vain too, claiming to hate anything she perceives as more beautiful than herself.
