Noroi no Ningyou

Noroi no Ningyou is a moving, cursed Japanese doll that was once abandoned by humans but taken in and animated by the former leader of "Kaikigumi". However, due to her deep-seated hatred for humans, she went too far with her malicious pranks and was sealed away by the former leader. In the early stages of the story, her seal is accidentally broken by the protagonist. Although she initially attempts to seek revenge on humans, she is deeply moved by Mechako's genuine appeal as a fellow lonely soul and decides to join "Kaikigumi" as its very first loyal member. She possesses a unique cursed ability to make her target's hair grow instead of her own. While she can be somewhat foul-mouthed, she is surprisingly knowledgeable about various supernatural phenomena and acts as Mechako's constant mascot-like companion.
