After a long wait of nearly three years, the second season of the Attack On Titan anime is coming. Admittedly, the only set date is the small range of 2016. I've heard that the release date is rumored to be July 26, which a pretty long way off. So, I've complied a list of five anime to hold you over until it gets here. None of these anime are very long ones, which means that you can probably watch most or all of these anime before July. Each one of them is, in someway, similar to Attack On Titan. Some of them have a greater similarity than others, but all of them can be tied to it in one way or another.
