Yui Kanzaki is a main character in Kamen Rider Ryuki. She is the sister of Shiro Kanzaki, the creator of the Decks, and she, with Shiro, is the partial creator of the Mirror World and it's Mirror Monsters. She spent most of the series opposing her brother on the Rider War.
History
Yui at heart is a young innocent girl who is caring to anyone she meets. However, this trait is what causes her the most trouble as a majority of the people around her are associates of the Rider War and only wish to use her to their advantage. She hates fighting, as shown by the multiple times that she attempted to stop Shinji and Ren from fighting each other. Yui originally lived with her grandmother, but when her grandmother went overseas, she met Ren somehow, although how this occurred is not specified in the series.

She was kidnapped by Kamen Rider Scissors to use as bait to lure out Shiro but Ren was able to rescue her before that happened. Later, she went to Seimeiin University to inquire about her brother but everyone she asks was much less than helpful. After finding her brother in a yearbook, Her past; which she previously had no memory of, began to reveal itself to her and she met Professor Ejima who worked alongside Shiro during the development of the decks. Ejima died in her arms but not before he told her that everything would have been fine if she had never existed.
Episode Final

But however, it didn't turn out well as Shinji didn't come out due to rain as she returned home. Saddened of what happens to her, Yui's mirror counterpart pays her a visit and accompanies her to play in the Mirror World. However things only getting worse as she will die when she returns. The mirror counterpart agrees to lend Yui her lifespan which will only last on her 20th birthday in an exchange for her drawings of the Mirror Monsters. Before returning, she visit Shinji (via mirror transportation) and plays with him for the last time.

Advent Card
Because they were designed by Kagawa and not Shiro Kanzaki, the Alternatives' Advent Cards differ from the ones used by the Kamen Riders. The terminals and images are printed crosswise, having the inscription Alternative Advent Card Alchemy System at the back. Also, there are green characters on the cards, which may give information to the Visor on what kind of card is swiped.
Slash Visor : The card reader of Alternative Zero/Alternative was mounted on his right forearm. The visor voice was different from those of real Riders, the voice was female. Another difference was how the cards were used with the visor. The cards were swiped (similar to the rouzers which would later be used in Kamen Rider Blade), which burned up with jet-black flame and disappeared when the card was vented.
