Roshiel is the one with a cigarette and Katan is the other one...

Ahhhh... big problem... because even if I have several volumes of Angel Sanctuary I understand absolutly nothing!!!!!! Well, I think it takes me 5 volumes to understand that Roshiel is a guy...(And I'm still not sure about it!!) I will try to sum up anyway.... It seems to me that Roshiel (who is the bad guy in A.S.) found Katan when he was a little boy, that's why Katan is so devoted to him... Then Katan fell in love with Roshiel but Roshiel act as a bitch with him!!! Anyway... there is a passage where Katan is about to die and then Roshiel began to cry (that's suprising and very bewildering to see such a bastard crying...)

But Katan is not dead!!!! (well, he lives in a coffin under the form of a monster or something like that... And Roshiel looks after him very closely)... Well, latter, some guys try to kill Roshiel so  Katan leave his coffin (he has now he's former human form... grrrr... I understand nothing!!!!!!) and save Roshiel!!! When Roshiel see Katan is alive and in good health he jumps on his arms, crying etc....
Well, even if I understood nothing, I found them terribly cute together (but in few months Angel Sanctuary will be translated in french and I will understand!!!! I'm happy!!!!!)
