In all honesty, Julius initially harbored intense precaution and nervousness in regards to Halibel.
The name “Admirer” was known well throughout the world, and alongside the Sword Saint, Reinhard, he was one of the four people in this world considered to be of the strongest caliber. The objective for which Julius and Anastasia had passed through the City-States, was also not something that would have been looked at favorably by the mayors who organized Kararagi.
Worst case scenario, they had entered the country with the resolve to face even Halibel.
Halibel: [But, ya got up ‘n surprised when ya met me fer real ‘n saw that I was actually a good-natured uncle, ain’t that right?]
Julius: [It is true that I was quite surprised. However, it was not your temperament that had surprised me. Reinhard, with whom you are considered to be of equal rank, is a friend of mine whom I can respect. I am also acquainted with Vollachia’s Blue Lightning, Cecilus Segmunt-dono, but he, too… is not somebody who cannot be conversed with.]
Halibel: [Ya seem ta be pretty darn well connected, eh? Well, if ya know Cecilus, then I guess ya wouldn’t be too surprised that I’m like this. Yeah?]
Stifling a laugh, Halibel sought agreement for his impression towards the strongest of the Empire, but by closing his eyes and maintaining silence, Julius decided to protect the honor of his acquaintance. –Anastasia's Companion Searching Chronicle III
