Since Summer is when I catch up on my Anime, I don't know that I'll pick up any of the shows from the new season, but some do look pretty intersting. There also seems to be a horror theme to many of the Summer shows, which is pretty cool considering I haven't watched a good horror show since Monster.
Highschool Of The Dead - HighSchool zombie survival horror show. May watch.
Seikimatsu Occult Gakuin - Horror/Comedy revolving around supernatural cases. Im in.
Sengoku Basara 2 - I don't know if I should watch even after watching the first season of Sengoku Basara. The first season really became a bit unbearable by the end. Someday maybe I'll watch it, but not this season.
Shi Ki - Investigation on the many inexpliacble deaths that keep happening in a quiet village. Sounds really interesting, another possible watch.
Kuroshitsuji 2 - Need to get around to watching the first "Black Butler" before watching this one, but it also looks interesting.
Nurarihyon no Mago - Interesting story about a guy who's part Demon. It's from Studio Deen which could mean it might turn out to be one of the better shows this season.
Tono to Issho - Comedy about the Sengoku period in Japan. Could be interesting, will see how it turns out.
The Legend of The Legendary Heroes - Title doesn't seem too appealing but it might turn out an ok show. Not in any particular hurry to watch this though.
Ookamisan to Shichinin no Nakamatachi - Some girl and her friends solving problems. May be my oddball pick-up this season. If I ever get around to watching it, haha
Rest of the shows this season are of the school-girl-panty-flash variety or digimon, haha. But at least there seem to be some shows with a lot of potential this Summer.
