Yuko also appears in the crossover manga Tsubasa: Reservoir Chronicle, where she assists the main characters in their journey across the multiverse, and is known as the "Dimension Witch" (次元魔女, Jigen Majo).

[3] Clamp artist Mokona said drawing Yuko was challenging due to the character's proportions, something she planned to change with their next work, Kobato.

[1] Sayaka Ohara voiced Yuko for four years, starting with the first Tsubasa: Reservoir Chronicle adaptation and ending with the xxxHolic original video animation (OVA).

Her deals with customers and cruel fates in some cases serve to show the readers the harsh reality of the real world which contrasts the shojo manga centered around a more optimistic view.

After she dies, Watanuki starts acting like her and decides that he will wait for her inheriting his unpaid price from the series' beginning as a magic that heavily slows his aging.

To grant him the ability of travelling across dimensions and save his friend Sakura, Yuko uses a pair of creatures named Mokona Modoki that are able to cross worlds.

[17] She then gives up her life as the price for Fei-Wang's two creations, the clones Syaoran and Sakura, to be reborn as normal humans in compensation for how they were used by the sorcerer because of her.

In the end, Watanuki has a series of dreams where Yuko gradually reveals herself to him; finally, she tells him that he has stayed in her shop for a long time and now has the power to leave it.

[21] In the xxxHolic Rō OVA, which takes place after her death, Watanuki receives a recorded tape from a girl that has Yuko saying "I'm home".

[25] Yuko is also in the video game xxxHolic: Watanuki no Izayoi Sowa and in the book Soel and Larg: The Adventures of Mokona Modoki.

"[39] Megan Lavey from Mania Entertainment enjoyed how Yuko interacts with her clients and her sense of humor which involves multiple references.

[41] Johanna from Comics Worth Reading agreed with Alexander, while Ed Sizemore from the same site admitted having taken a liking to her due to her personality and the fact that she has "the wonderful sensuality of a Hollywood femme fatale from the 30s and 40s".

[42][43] Her death scene has been referred by Active Anime's Holly Ellingwood as "tragic, inspiring, and beautifully, breathtakingly sad" for its presentation.

[44] Santos noted that while the loss of Yuko could have negatively affected the series due to her impact, it managed to retain the same quality, as Watanuki inherited most of her distinctive traits.

[45] The character's role in xxxHolic Rei was the subject of mystery due to her supposed death but reviewers still felt this incarnation of Yuko appealing.

[55] Santos liked the secret talks Yuko had with Sakura on the second half of Tsubasa: Reservoir Chronicle, as it gave the 19th volume of the manga one of the most interesting cliffhangers from the series even she is still a supporting character.

[59] As the series reached its climax, Active Anime and MangaNews enjoyed Yuko's development from a supporting character to one of the most important ones in the narrative.
