Yui Kanzaki is a fucking terrible character. She's whiny, she has no character development to speak of, she's annoying, she has no personality to speak of and she doesn't do anything to help out the protagonists.

She's a void of the character that the entire Ryukiverse is based on due to the Rider powers being made to give her a new life.

Her shittiness as a character is so bad, it affects others around her. I look at Shinji, Ren and Shiro, at their developments as characters and what they aspire for and think to myself, "This was all going to be squandered so one person with no motivation or personality could live." Ren had a fiance to save so he could change his life. Shinji wanted to save others and went outside of his normal boundaries in order to do it. And Shirou wanted to save his sister so badly that he created this sick game, kept trying to accomplish his goal despite death and realized he was wrong in his intentions.

Now look at Yui, does she change? No, is worried about her brother in the same way from episode 1 to 50. Does she help out the main chracters? In the first 2 episodes, she saves Shinji from being killed by Ren and told Shiji how to use the deck. And the story gives her the beginning of a subplot of revealing the truth about the nature of the Rider War, but that was given to Reiko from ORE journal. She becomes more of a burden later on with the Alternative storyline and her planning to comit suicide. Even characters that don't do anything like Hina from OOO, they still have a personality.

Usually when a plot happens, there is development and payoff. Yui is the pay off of all of the bloodshed, change and death throughout all of Ryuki. She affects every other character by making their contribution to Shinji and Ren's character development have the shittiest payoff I have ever seen for any sort of plot I have seen in any sort of Fiction so far including the Rider series I have seen

And this is what I believe was Kamen Rider Ryuki's biggest flaw, Yui. You can't fix a problem like this in an alternate ending. She's still fucking whiny and useless in the movie. This character needed to be rewritten. I'm not saying she was a bad idea, I mean her existence creates the interesting dilemmas of Alternative and Shirou it that she was poorly written and acted.
