Blair Cat is a supporting character in the anime and manga series Soul Eater. Despite her magical powers and playful personality, Blair is not actually a witch but a cat with strong magical abilities. She often helps the main characters, Maka and Soul, sometimes causing comedic confusion due to her seductive and mischievous nature. Blair is notable for her ability to transform between a cat and a human form, and she brings a lighthearted, humorous dynamic to the series while occasionally assisting in battles.
