There, he is tasked to break the enemy werewolves’ code, which the werewolves are using to encrypt their radio transmissions. Testa is astounded, as the only sound the encrypted code produces is the howling of a wolf. His research yields no results, and he resolves to capture a live werewolf for better cryptanalysis. After exhausting all possible means, he finally finds a female werewolf, Yonaga.
