The Titan-sized Attack on Titan is exactly what it bills itself as: a collected volume of the manga sized so that it could be read by the series gigantic monsters.
The Attack on Titan manga began in 2009, and it’s scheduled to come to an end next month when its final chapter is published in the April 9 issue of Bessatsu Shonen Magazine.
Specifically, it’s scaled to fit the hands of protagonist Eren in his 15-meter (49-foot) tall Attack Titan form.
