Yodaka

His actual name isn't known but he was given the name Yu Nozuki (野の月づきユウ, Nozuki Yū) as an undercover name for his current mission to protect Aoi Mukai. Yodaka is more of a shy person who struggles to talk to other people, finding social interactions very awkward. He avoids most interactions and large groups of people as a result. He fears disappointing friends, so he avoid befriending others despite desiring them. He later learns that his fear has robbed him of experiencing actual friendships and takes a step forward through befriending Aoi.
