Mnemosyne - Just done watching the last episode of this anime which is a six episode series produced by Xebec and Genco. The anime is to commemorate the 10th anniversary of AT-X network and features grotesque and erotic visuals (rather hentai if you ask me). The story follows an immortal female private investigator performing odd jobs to get by but she finds herself constantly hindered by strange cases which link to her past and unique abilities. Very interesting characters used inside and the whole grotesque part adds to the mystery of the story. The chronological way of how the story moved was also something that I liked a lot with the supporting casts constantly looking different and changing every episode. Somehow 6 episodes were just nice I guess because if they made it into a series like Naruto or Bleach it would be really draggy. So if you're into grotesque anime, this is one series you can check out. More info here.
