You can watch stuff legally on Crunchyroll, FUNimation (and their YouTube channel), The Anime Network, Viz Anime... there are probably more, but I can't remember them right now. I don't know which has more choice, better prices and the like in the US overall (Crunchyroll has the most new stuff by a mile, though), so I suggest you either research that yourself or wait for a response from someone who knows US anime streaming better than I do!
100% of information in signatures on this forum involving percentages is false. If you feel as cheated by this atrocity as I do, don't you dare copy this into your signature.
Hold on... if this percentage was correct at the time of print, that means the actual percentage of false information is less than 100% if this signature is included. Which means that... no! I've become a slave to the system!!
