Yuri is interesting because he doesn't get on Lucifer's case for having no feelings or morality, and is casually open about stuff like memories. Yuri is actually the first person to willingly show Lucifer his memory, and that's actually something Lucifer enjoys! He's a snoop, and he likes knowledge, and perspective. So frankly if he could he would watch everyone's memories all the time 8D; So basically Lucifer likes him for being decent, non obnoxious conversation.

Kazu is just kind of funny because Lucifer likes to poke him to see if he's read him right. Kazu reminds him of Katou! Which is to say, the type of person who will get a crush on you and follow you around for life after you kick his ass and then proceed to treat him like shit. SO FAR HE HAS BEEN CORRECT.

Kazu on lucifer =x?
