The Attack on Titan anime is finally, finally coming to an end, drawing the curtain closed on a saga that began as a dark fantasy tale of survival and quickly veered into unexpected territory. If you're looking to revisit the source material manga, then you can grab several box sets of Attack on Titan manga paperbacks for low prices at Amazon. You can also save on Attack on Titan Blu-rays to watch after you read the source material.
These are your regular pocket-sized manga books, compiled as seasons and packaged inside slipcases. Like other traditional manga, you'll be reading these from right to left. The first box set includes four volumes, which roughly corresponds to the first 13 episodes of the anime, while the second box set rounds out the second half of the debut season with its included volumes. The box sets move in sequential order and cover the entire Attack on Titan story arc. We also have several of the adaptations linked in case you'd like to see the brutal action unfold via animation--and the Attack on Titan anime doesn't disappoint in this department.
