Yep, and I'm greatly looking forward to next season's sequel!
The final episode was fantastic in its own way, but it left the series on quite the cliffhanger.
Well I've now read the first volume of
Ibitsu, which was fantastically creepy.
I'd recommend it on that basis, and just hope it ends well.
As for other horror manga that I've read before,
Hideout's a good singe volume story,
Franken Fran is brilliant if you like body horror, and
The Drifting Classroom is a classic.
Anime-wise, I'd suggest
Shin Sekai Yori,
Blue Gender, and definitely
Higurashi no Naku Koro ni if you've not already seen that.
For manga, I read full volumes either as paperbacks or on Kindle, so I've never had to worry about that (apart from when bookmarks fall out
). Anime-Planet does have a manga chapter count function though, so it might be worth trying it out. I've definitely found the episode counter useful when coming back to anime series after a long time!
