Saiga
Saiga is a very physical person. Physically aggressive, physically affectionate, physically dominant. He spends so much time in the spiritual plane that he purposely revels in the feelings of the physical world.
His devotion to Kakei is complete, as is Kakei's to him. Their mutual love and trust is the one thing about them that is innocent and beyond reproach.
Not long after they met, Kakei told Saiga of their destiny, of the Green Drugstore and the two boys. To Kakei's amusement and bemusement, Saiga had found it fascinating. Who wouldn't want to be surrogate fathers to such interesting boys?
Okay, long footnote. I absolutely love these two. They are part of a long line of a great tradition of Clamp characters that, while being extremely manipulative, sadistic, and generally creepy, serve as guides/surrogate parents to the main characters in the series, such as Eriol (from CCS), Clow Reed (from CCS and Tsubasa) and Yûko (from XXXHOLiC), and are only manipulative for the good of those that they're 'helping'- the fact that they happen to amuse themselves a bit along the way is only 'coincidental,' of course…
I wanted to delve a bit farther into their relationship, but I didn't have the time to do it in 100 words (a drabble is supposed to be only 100 words, after all)… perhaps later I'll write another version of the fic without the limit, going into the other aspects that I wanted to go into. Or maybe I'll write a bit of an essay… I do that sometimes… Oh, yeah, about the 'physical plane' bit… I'm thinking that Saiga's numerous naps might possibly be some type of trance… Either that, or his-as-yet-unknown power takes a lot of energy out of him, forcing him to nap a lot. I decided to go with the trance bit in this fic, because I liked how it fit in the beginning.
