Zero didn't see his mission partner the entire afternoon. He spent it with Kruz who gave him a private tour of the Academy grounds. Zero enjoyed the bat demon's company tremendously. It was vastly different from spending time with Truen or Baal. Kruz laughed alongside Zero at the funny things they saw and made jokes. It was a very new experience for the apprentice.
Zero learnt a fair bit about the bat demon too. Apparently, Kruz was a student accepted for his ability to do reconnaissance in ways that others couldn't. Kruz was able to transform into a tiny bat and had a superior sense of hearing and smell. Despite his physical disability with his eyes, a trait from the bat demon clan, Kruz was able to determine the location of things and objects through echolocation. Zero was excited to know how that ability worked because he had it too. It was tricky to use and Zero's head often hurt from listening to the multiple echoes when he used it.
