Shiki

Both are dealing with the occult, but difference is quite large too.
Shiki deals with vampires/zombies hybrid? and is more of mystery, psychological.
Occult Academy has some comedy, deals with a general mix of occult like spirits, witchery etc. and has a feeling of adventurous spirit and time-travel. A teeny little bit of romance too.
Both are in Summer 2010 anime season.
