Alba

The heroine of "Eating the World Tree." She is the guardian of the World Tree responsible for knowledge and the daughter of the previous Sage. She has an impression similar to that of a noblewoman from Northern European descent, with her white hair. She always appears to maintain a poker face, but in reality, she is kind-hearted, lonely, and has a timid personality. Due to this nature, she received advice from her mother, the previous Sage, that despite her brilliance, her delicate emotions would lead her to use her wisdom elsewhere, making her the weakest mage among all Sages in history. She was warned never to become a Sage. Moreover, from the description in the Sephirot's Blessing episode, it seems she has an authoritarian tendency, thinking that her way is always right and that no other method could exist. However, based on the depiction in the story, this might be a side effect of knowing too much. Additionally, considering that the family of the Sefirot, including Alba, has evolved to exclude emotions to a point where they are considered avatars of reason, this might be a trait of the Baek family itself. Separate from that, her love for Lee Si-heon is sincere, struggling to act rationally but ultimately giving in to the emotions stemming from affection, as depicted. The fact that she chose affection in the end despite the internal conflict and confusion implies there was a reason behind Alba's mother's advice for her not to become a Sage. Furthermore, she also has a tendency towards possessiveness, similar to her daughter Wiki, and is known to derive some enjoyment from controlling and manipulating people.
