I read the manga but I must say, the anime is doing a pretty good job too! <--- usually prefers mangas over animes =p Added some new scenes that weren't in the manga without changing the basics too much, but there're only 4 episodes currently. I think they're gonna deviate from the manga later on and add an original anime ending to it, hoping it'll be good
Partially random, but Mephisto is total ♥ xD
