Ayashi no Ceres:
A very original plot line, immersing a young woman on her 16th birthday, into a world of danger and constant threat while those who are around her and those who she loves are hurt. With love triangles that are sometimes heart wrenching and at other times very sweet. And with a very important message which you will be blatantly told if you haven't already figured it out by the end of the series.
Characters that are simply amazing, follow them all through their pain and trials that they have to overcome. All are excellently portrayed and their feelings really reach you. The romance between some of the characters is just grand, it really gives and shows you the true feeling of love.
Soundtrack is just amazing, opening song: Scarlet, must be hands down one of the best openings for an anime. The background played throughout the anime is outstanding with beautiful instrumental and piano music. The voice actors, just wow, their acting, the feeling they put in each character, it is just outstanding, some scenes I actually think in the recording studio the voice actor actually cried.
What is so good about this anime?
For an anime that was released in 2000 the art is simply amazing. The plot line is so intricate and very original. The romance between various characters that really portray their anguish, sadness, happiness, confusion, and love. An amazing soundtrack that completely fits the mood and just makes you want to listen to the songs over and over again. I have to say, this is one of the best romance anime's out there. Enjoy this series.
