First off this is not an anime, its a collection of  short stories, good ones.  H.P. Lovecraft was a horror fiction writer.  The tales deal with madness, death, and the Cthulu Mythos (now a somewhat cult following).  The stories may have a loose plot thread but most are independent.

plot(s):

very indepth stories, they realy draw your attention

characters

the characters are good.....but don't last very long, insanity, death, great old one, whatever you wanna call it their gone

length

just like coconuts, big ones, small ones, some as big as your head

rated

a.k.a. R

This stuff deals with some majory confusing things, and is rather strong in its content, not for frigile minds, blood, insanity, death, cults, all writen in a complety unique style, be warened

overall

if you read, and have a strong stomach, read it

( i borrowed this pic from a fanfic, realy good to)
