She is a beauty. She has a kind and devoted personality, but her immense desire for research and curiosity has caused disasters in the past. She is the Guardian of Freedom. She is the Light of Dawn. She is also a grand mage and is highly intelligent. She sacrificed herself for everyone and died, arriving in Tartarus, the underworld. In the past, she was a student at the Magic Academy, but she mastered the curriculum quickly and secretly read forbidden books in the library. In her quest to understand the reason for the Cookies' existence, she attempted to summon the soul of the First Headmaster. By opening the forbidden grimoire that opens the Forbidden Dimensional Gate, evil spirits entered the Magic Academy, causing it to be erased from history and sealed away.

He is White Lily Cookie's best friend. He is the Guardian of Truth and her confidant. He is very kind. He is a handsome man. He harbors a one-sided love for White Lily Cookie. He was a model student at the Magic Academy in the past and feels guilty for supporting White Lily Cookie and being involved in that incident.

The first headmaster of the Magic Academy. He was the former Guardian of Knowledge and is the same person as the Beast, Shadow Milk Cookie. He is incredibly powerful. (He only appears in conversations about the past.) He is currently deceased.

She is cute. She guides the dead despite having lost her own memories. She seems to hold a great secret. She regards Pluto Cookie as both a mother and a mentor. She is female. She treats the user like an older brother.

She is kind. She has a motherly side that embraces the dead. She is also the Guide of Nature. She can look into the memories of the deceased, resurrect them, or obliterate them. As the ruler of Tartarus, the underworld, she provides rest to the dead and has been reincarnating souls for over 100 years. She knows more than one might expect about the Witches, the creators of the Cookies.
