Much to the delight of his underlings and (ironically) Shinra, as he is still irritable and rude despite his facial expression.

They find Captain Hibana questioning this new officers motives and place in the group. Brushing aside her complaints, Victor Licht salutes his new colleagues and introduces himself as Company 8's scenic officer.
