Abandoned outside an orphanage when he was just a baby, Yuki is a boy with no idea where he came from or who he really is. Now in high school, the teen is plagued by odd dreams, death threats and an ability to see the negativity that dwells within people's hearts. One night after being lured into a trap, a mysterious and handsome man named Zess saves Yuki from being killed before disappearing into the night. Then, with the sudden arrival of his long-lost brother, the orphan finds himself pulled into a new world where he can not only learn about his powers and how to control them, but also becomes aware of the evils that lurk in the darkness. Can Yuki finally find the place he truly belongs, and just why is Zess so protective over the young boy?
Both series deal with incarnations bringing age-old grudges to the modern world, alongside with magical powers.
While UraBoku is more friendship-driven and Ayashi no Ceres more about lust, both share a dark, sinister atmosphere. Both are very melodramatic with blood and tears plenty.
Of course both feature a mysterious, stoic characacter protecting the main character, and these tough guys seem to share a fashion sense too, in good and bad.
I would see Ayashi no Ceres being more plot-driven and wholesome while UraBoku doesn't seem to reach a climax, at least not now when 24 episodes are out. Ayashi no Ceres also has a horror-vibe while UraBoku is quite completely about human relationships and emotions.
STN is a secret organization charged with capturing witches of all ages who misuse their inate ability of the Craft. Its newest recruit is a young girl named Robin, who wields the same power that she is helping to control. While skillful at their ability to detain quickly, the number of witches keeps seeming to increase, and the misuse of power grows stronger, casting a shadow of doubt as to what is really going on. For STN, there is much work ahead, and for Robin, her troubles are just beginning...
There are a few similarites between Witch Hunter Robin and Ayashi no Ceres. The stnj of WHR is very similar to the Mikage gamily of AnC. Both are looking to "better" humanity through people who have more evolved genes. Aya and Robin both are strong female leads who have strong unusual powers. The tension between Robin and Amon is reminisent of Aya and Toya's relationship. I discovered Ayashi no Ceres years after I watched Witch Hunter Robin, and while watching Ayashi I kept thinking to myself that I really wished someone would have told me about Ayahi right after I finished Robin.
