Iguin

イグイーン

Iguin is the Brimmed Cap Witch who sold a mysterious magic book to Coco. Their motivations seem connected to getting Coco to use forbidden magic. They appear to be incredibly powerful, wielding magic that goes beyond the scope of normal witches. They also possess incredible agility, capable of making jumps while casting spells. They rarely appear, except to interfere with Coco from the sidelines.
Iguin is mysterious and enigmatic, constantly talking about some prophecy, mentioning that Coco is a child of hope and that forbidden magic should be brought back to the world. They appear to get very angry when Sasaran goes against one of their ideas, so it is likely they will have an angry response when allies disagree with them.
Iguin uses the generic Japanese pronoun 私 (watashi), which serves to further mask their gender and identity.
