Damn that sounds like some interesting anime ill have to go check them out. But im sorry to see that me wondering what this anime was is irking you. I would like to think you have encouraged me to do just that so more people can find out about the anime that you like, when were these released? the one about the giants sounds pretty dope.
April 6, 2013 Attack on Titan began, July 4, 2013 for Free! and Dangan Ronpa.
It simply irks me because it took me less than five minutes to find the information you're looking for but instead you'd rather have someone else do it for you even though it'd take a longer time for me to relay the information back to you. Additionally, if you do not want to watch these shows from just reading this thread, let alone the internet hype, there is very little hope of me convincing you.
