Keiji

Keiji (ケイジ) is a member of the Survey Corps and a part of Hange Zoë's squad.

Story
Keiji first appears participating in the operation to capture Annie Leonhart, the Female Type Titan. After Annie encases herself in crystal, Keiji hacks at it with his sword until being ordered to stop by Hange Zoë. He is later seen in chapter 41, berating Eren for disobeying an order to stay out of fight. He was again seen in chapter 43 with the rest of the Survey Corps fighting the Colossal Titan. After the Colossal Titan falls onto Eren Yeager and the Armored Titan, Keiji is among those who are wounded from the impact of the attack.
