A mysterious girl and nameless upperclassman at Mitakihara Middle School who looks exactly like Homura Akemi. She is one of the "Witch-girls" who came to the living world from the Law of Cycles via Nazuka-Sone. She is also a magical girl. She is accompanied by "Zi Dingxiang" and "Selma Therese." These two speak to Wasu casually, as if chatting with a friend. Zi Dingxiang speaks elegantly, ending sentences with "ne" or "yo." Selma Therese has an innocent, childish tone. Wasu is popular among other students. First person: Watakushi (formal/ladylike). Second person: You. She addresses others by their full names without honorifics, but calls Madoka Kaname alone "Marguerite." Though she has the same face as Homura Akemi, she has red eyes and long black hair with a different purple tint. She wears the same black-collared uniform as the other two. Her headband is also different from Homura's, featuring a white cross pattern on a black background. Her magical girl outfit incorporates motifs such as gears based on the design and silhouette of the "Stage Construction Witch (Walpurgisnacht)." She behaves with grand, theatrical gestures and tries to close the distance with Madoka Kaname rapidly by calling her "Marguerite," which leads to suspicion and conflict with Homura Akemi. Despite having the same face, her personality is entirely different; she performs eccentric acts like lying down in a fountain to greet people or entering homes without permission. She is extremely optimistic and high-energy, but is actually calm underneath. When pressed by Homura Akemi on "Why did you steal my face?" she doesn't really know herself. Conversely, she feels a sense of rivalry, stating she "doesn't like how someone with the same face has such a twisted way of loving." Long ago, the world's curses were not Witches, but uniform "Wraiths" without individuality or names, much like the current ones. Magical girls fought these Wraiths, but were destined to turn into Wraiths themselves when they fell into total despair, losing their names and individuality before vanishing. Wasu, a magical girl who contracted with Kyubey out of pity for them, became a magical girl with the wish to "save all magical girls," just like the later Madoka Kaname. As a result, she gained a unique magic to transfer the curses accumulated by other magical girls to herself and purify them. To the magical girls who had no choice but to head toward despair, Marguerite's existence was "hope" itself. However, unlike Madoka Kaname, who gained the power to grant any wish (karmic destiny) through Homura Akemi's loops, Marguerite had a limit. The magical girls whose purification Marguerite couldn't keep up with turned into Wraiths one after another, and even as Wraiths, they rushed toward her, screaming Marguerite's name for salvation. Thus Nazuka-Sone was born—a Law that "saves" magical girls destined to vanish by giving them new names and individuality, allowing them to be reborn as Witches. Marguerite herself, reaching her limit before she could "save" all magical girls, merged with all the curses that couldn't become Witches, losing her ego and name, and remained in the world as the accumulation of nameless curses: the Stage Construction Witch, known to people as Walpurgisnacht.
