Regina

レジーナ

A mysterious girl in a black dress who appears to be the second-in-command of the Selfishness Trio and claims to be the daughter of King Selfishness. She frequently acts like a spoiled, demanding girl who typically bosses the trio around. She possesses the power to compel someone to give birth to a Selfishness, even if they harbor no selfishness in their hearts.
Regina is selfish, vain, and spoilt, treating everyone else as her servants and, as she puts it, hating anything else more beautiful than her. If she fails to get the Selfishness Trio to do what she wants, she behaves like a child talking to her older siblings, threatening to tell on them to her father. She is also playful and tries to drag Mana around to make her play instead of attending classes or being responsible.
