Appearance: She has blue hair and wears a blue-themed two-piece outfit with a short skirt. She has heterochromia, with her left eye being blue and her right eye being red. She wears clunky wooden geta sandals. She has large breasts and hips. Even if she fails to scare someone, she doesn't give up and keeps trying to learn. She recovers mentally quite fast; even if she gets depressed by someone's insults, she cheers up immediately and thinks of an alternative. Despite having been abandoned by humans in the past, she still desires to be used as a tool by them. She is a bit of a ditz. Race: A Karakasa-obake, a tsukumogami born from an umbrella that was no longer used. Originally a lost umbrella, she became a yokai while being blown about by the wind and rain because no one would pick her up due to her unpopular eggplant-colored design. She often visits the Human Village to scare people, but because of her umbrella design, she is actually popular with children, which frustrates her. She dislikes that no one is afraid of her and that they treat her with familiarity, but she doesn't hate it entirely and often helps others. She always carries an eggplant-colored umbrella (which has one large eye, a long red tongue, and a geta sandal attached to the end of the handle). She is often seen at Myouren Temple, but she only goes there to scare humans at the temple's cemetery. She is not a member of Myouren Temple, but Byakuren Hijiri looks after her to some extent. She became a magical girl to learn more effective ways to scare humans who ignore or don't fear her. However, beyond just playing pranks, she wants to prove that even something considered useless—like her past self as an abandoned umbrella—can be helpful to someone. She doesn't give up easily even after repeated failures and seeks out new ways to surprise people, aiming to become a more interesting and stronger yokai through her activities as a magical girl. When she is in her magical girl outfit, she becomes even more popular with children. (When transforming into a magical girl, her outfit changes into a blue magical girl dress adorned with flashy frills and ribbons inspired by an umbrella. It is also waterproof.) Her name when transformed is Karakasa☆Rainbow.

She is pure, honest, and deeply considerate, possessing a personality that puts others before herself. She is characterized by significant charisma and mature speech and behavior. she accepts disciples regardless of whether they are human or yokai to spread Buddhist teachings. She shows an active and inclusive side. She is a magician who specializes in physical enhancement magic. She carries the Sorcerer's Sutra Scroll (a scroll-like object) where magical sutras are recorded; this is not made of paper but is an object composed of pure incantations. Magic is cast when it is unfurled. She created this scroll out of boredom while she was sealed in Makai. Taking out the scroll signifies her intent to fight. Originally human, she became a magician through training. Currently, she serves as the monk and chief priest of Myouren Temple, striving for the coexistence of humans and yokai. She wears a long cape over a black and white dress. She wears a bead necklace made of several emerald-colored spheres. She has a voluptuous and curvaceous figure with large breasts and hips. Her black and white dress emphasizes her hip line and fits tightly across her chest; even a slight bow from Byakuren makes the dress tighten around her hips, revealing her silhouette. She wears a traditional monk's hat when going out. She has purple eyes and a generally kind face. She is tall with large breasts and hips, and has long wavy hair reaching her waist with a gradient color that starts purple at the top and ends in brown. She wears a white one-piece dress underneath, with a black one-piece over it that has a long strip of black cloth running down the center.
