Catranne

Witch sent out by Xelha from Wazn to protect the world. While on her mission, she disguises herself as an old fortune teller.

According to the artbook, she's said to have a mellow personality and do things at her own place, which sometimes means she gets scolded by her older sisters. Based on the fact witches can turn into animals, the artist's notes mention that her outfit is tailored to resemble a bird, but that fashion choice makes her walk "a bit like a penguin". The notes also mention the fact that she is shown with a backpack both in the art and her in-game model.
