Ryuki / Ryou×Ruki
It's obvious where the word Ryuki comes from. RY for Ryo and UKI for Ruki. And it makes Ryuki!Ruki and Ryou have a really special relationship to each other. It's not that obvious love thing going on between them (like between Juri and Takato). It's annoyance from Ruki's side and flirt from Ryou's. Ruki is almost always annoyed by Ryou's appearance. When they first meet in the 28th episode she doesn't like him because everybody think he's better in Digimon TCG (Trading Card Game). Ruki is very competitive and Ryou is supposed to be better in the game. She can't stand that and she hates how Hirokazu and Kenta adore the 'Digimon King', even though she's called the 'Digimon Queen'. Ryou on the other side is always glad to see her. He flirts with her all the time, she's kinda the only one he has any kind of relationship with. Well, their relationship seems to get better towards the end; Ruki isn't that annoyed by him anymore and she even cries when he asks her for her power to defeat an evil D-Reaper (she's afraid he might get hurt <3). But their relationship doesn't change completly, as we can see from the sixth Digimon movie (The Runaway Digimon Express) and the Drama CDs.
