Lance Corporal Balke

Lance Corporal Balke is originally an underling of General. He is initially very interested in the Luger code and shows great curiosity on whether it's been cracked yet.

(Spoilers from this point on)

Upon confirming that the Luger Code hasn't been deciphered yet, he reveals himself to be a ware-wolf and attacks the others, including Yonaga. It is due to this fight that Yonaga initially turns Testa Lielbelle into a ware-wolf. He soon after is killed by Testa in wolf-form.
