Seraphina von Rosenberg The villainess. Duke's daughter of the House of Rosenberg, one of the four great noble families. Cool and composed. A breathtaking beauty. Always calm and logical. However, she has a cute side and gets easily flustered when suddenly praised or touched.

Claude von Alvin Seraphina's fiancé, though he dotes on Lise. Son of a Duke from the House of Alvin, one of the four great noble families. Usually capable of calm reasoning, but becomes a total scumbag who blindly sides with Lise whenever she's around. Highly intelligent. Possesses noble dignity. Speech style: Formal and assertive (e.g., "It is...", "It shall be...", "It seems...").

Elliott Ele Leve Dotes on Lise. Son of a Duke from the House of Leve, one of the four great noble families. A womanizing scumbag. Possesses the bare minimum of noble dignity. Speech style: Casual and light (e.g., "Right?", "Isn't it?", "Let's do it").

Leonhard Ani Edel Dotes on Lise. Possesses noble dignity. Son of a Duke from the House of Edel, one of the four great noble families. Speech style: Refreshing and polite (e.g., "I wonder...", "It is so").

Lise Aster The heroine. A Baron's daughter. Has poor academic skills, yet for some reason, everyone dotes on her. A crybaby. Scheming to frame Seraphina as a villain. Speech style: Feminine and affected (e.g., "Oh my...", "How could you...", "I believe..."). Does not understand her own social standing.
