Eriol and Yue/Yukito
Eriol and Yue seem very close. When Yukito first saw Eriol, Yue immidietly took over, questioning his former master. Eriol merely smiled and put him to sleep by merely raising his hand. He seemed quite gentle with Yue, quickly changing him into Yukito.
Yukito is oblivious the whole time (as usual ^_^). He doesn't know what's going on but is starting to notice that there is something wrong with him. The balance in Yue's energy is unstable, causing him to dissapear. Touya also notices this. Eriol and Yue have not been introduced.
