Anime 25777 Shingeki No Kyojin Season 2 Userrecs

Both shows are sequels to two of Wit Studio's biggest works. Each show picks up right where the previous season ended. Humanity is on the brink of extinction in each show. Titans have almost devoured all of humanity in Attack on Titan. While in Seraph of the End vampires have almost wiped out humanity. Each show has giant monsters that humanity has to take out, although they are not the main threat in Seraph of the End. The main character in both shows has a mentality of wiping out all of the enemies because they killed his family. The main character can also transform into something else. In Attack on Titan Eren can transform into a titan. While in Seraph of the End, Yuu can transform into a demon.
