Shiki vampire anime opening theme
Although the pacing, the story itself, and the dynamics of the characters are all slightly different, the Shiki vampire anime that has surpassed all the others on this list is legend. With an almost scientific level of detail, Shiki represents a "vampire" with a wealth of information and observations, many of which are simply displayed directly for the audience to learn for themselves.
Most horror stories elevate their level of horror by giving the audience a fantasy. But Shiki's vivid detail actually makes it more haunting in a special way.
