No worries no spoilers.
Many have told me the manga is better then the anime i strongly disagree
this anime pulled me in since the pilot episode.
if your a fan of horror/thrill then i would strongly suggest this good overall anime.
it is easily something to put on your summer watch list.
Pros
Every episode packs a punch you will every moment of it
pity for protagonist which always makes shows good
intro of course is good
although story lacked depth it was easy to follow and fun to watch
cons
little to no backstory
slightly rushed
And you will soon know what the other con is after u watch the show
thankyou
