Kagome is a normal high school girl who falls into a well, transporting her back in time to the feudal era. Upon her arrival to this world, she mercifully unleashes Inuyasha, a half demon. As if this isn't enough, she also discovers that she is the bearer of the Shikon no Tama, a jewel of great spiritual power, a jewel which has just shattered into a million shards. Now, along with Miroku the priest, Sango the demon hunter, and Shippou the mischievious fox-demon, they must set out to find the Shikon shards and defeat the evils of the demon Naraku.
Santa, the drummer of CLIMB, has just left the band after finding his girlfriend in the arms of a friend. Along with Yuki, the lead guitarist, they start their own band called "Lucifer, The Fallen Angel," and set out to find new band-mates. Recruitment is not easy, however, and on a search to find a vocalist the duo runs across a promising bass guitarist and a local hotel's piano player and singer who has been wowing patrons daily. With little time to spare, can the two round up the talent they desire, or will Sakuya let his anti-social personality hold him, and his newfound band, back?
This might seem like an odd recommendation, since the stories are quite different. However, both feature a main male character who's handsome, quiet, and has a mysterious past (Tooya in Ceres vs. Sakuya in Kaikan Phrase). In both cases, the token character has a romance with another main character that's central to the plot. If you watched one of these series and found that your enjoyment of it was increased by said character, you'll probably get a similar feeling watching the other.
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.
