She and Satan were living together, so I'm guessing the regular way. She seemed pretty content to stay with him till the end of his life, so I think she cared for him very much. Not the same love as she had for Shiro Fugimoto, but she loved him in her own way and was happy with him. At least that's what I'm getting from it. :)
Sometimes you only need one time ;)
I doubt they had sex, she is too naive and stupid to know what it is and Seten I won't even talk about. he even more clueless about this kind of crap so who knows ╮(￣▽￣)╭
If clueless and stupid ppl wouldn't be able to have sex, we would have a really different global society atm. :) I did not doubt that that is the kind of relationship Satan was looking for.
Yuri's is sexually attracted to Shiro and Satan's host body is Shiro's clone, so why would she not be sexually attracted to him? Don't mistake kindness for naivety or stupidity. :)
Erhm, I'm probably stupid but can someone tell me how Yuri got pregnant ? I mean, in the previous chapter, she didn't looked like she was in love with satan ? so i'm like how ??
