Attack On Titan: Before The Fall Vol. 9

Written by Ryo Suzukaze with illustrations by Satoshi Shiki, Attack on Titan: Before the Fall is the manga adaptation of a series of light novels serving as a prequel to Hajime Isayama’s Attack on Titan.
The story is set 70 years before the original. It follows two stories: one focusing on Angel Aaltonen, the inventor of the Vertical Maneuvering Equipment used to fight Titans, and one focusing on Kuklo (the “Titan’s son”), a boy found in Titan vomit who goes on to join the Survey Corps.
The rebellion crashes down after Xavi’s infiltration in volume 9 while Kuklo saves Sharle using the Device. This volume includes chapters 29 through 32 along with the extra "Budding Ambition" in Japanese.
Notice: This manga is written in Japanese.
