Mofurun is a teddy bear who originally belonged to Mirai Asahina and served as her childhood companion. When Mirai and the young witch Liko first transformed into the legendary Pretty Cures, the magic brought Mofurun to life, granting her the ability to speak, move, and eat. Her speech often ends with the suffix mofu.

In personality, Mofurun is gentle, perceptive, and deeply caring. Despite her small and cute appearance, she often displays wisdom beyond her origin as a stuffed toy. Her primary motivation is the happiness and safety of her friends, especially Mirai, to whom she is unwaveringly loyal.

Mofurun plays an essential role as the transformation device for the heroines. By inserting Linkle Stones into the bow she wears and holding hands with her, Mirai and Liko are able to transform into Cure Miracle and Cure Magical. She also possesses a natural sensitivity to magic, allowing her to detect the presence of other Linkle Stones. During the original series, she also helped care for the younger fairy Ha-chan.

In the sequel series Witchy Pretty Cure!! Mirai Days, set several years later, Mofurun continues to live with Mirai while Mirai attends university in the non-magical world. Their bond remains as close as ever, and Mofurun continues to accompany and support Mirai in both everyday life and magical battles. Over time, she has developed from a simple plush into a wise and capable ally, and on certain occasions has even been able to transform into a Cure form herself when empowered by a special wish, allowing her to fight directly alongside the other Cures.

Mofurun’s most notable abilities include her function as the key to the Cures’ transformations, her magical detection, and her steadfast emotional support for the entire group. She is a constant presence who represents the unbreakable connection between Mirai, Liko, and the world of magic.
