Attack on Titanis insanely popular, a mainstay on the bestseller charts. Not only that, but the first volume keeps charting, meaning more people are getting drawn into the story all the time. The villains of this story are giant creatures who are the living embodiment of pointless destruction: All they do is eat people. (It should go without saying that this is a very gory manga.) They are super weird looking, which actually makes them pretty scary, but they are also clumsy and stupid (except for a handful of abnormal specimens with special powers). They don’t seem to feel pain, and they are almost impossible to kill. To escape the Titans, humans have taken refuge in city protected by three concentric walls. The walls have been there for 100 years, so long that no one knows where they came from. The Survey Corps that defends the walls acts as humanity’s last line of defense, and the story follows a few key members through their work for the Corps and their investigation into the Titans’ origins. And that’s just the setup; nearing two dozen volumes in, things have only gotten weirder.
