Iguin is the Brimmed Hat Witch who sold a book of forbidden magic to Coco. His motivation is somewhat unknown, but it has something to do with Coco. He appears to be incredibly powerful, possessing magic that is beyond the scope of normal witches. Iguin also has incredible agility, being able to jump while casting magic. He rarely appears except to interfere with Coco from the sidelines. (Source: Witch Hat Atelier Wiki)
