IMO, Yuu is Kigurumi... My guess is he suddenly got the urge to dress up in a costume and go around making people happy and so on... also given the fact Yuu bearly talks the role was perfect for him...

But in terms of the actuall where abouts, i belive it is thought that Yuu is actuall on a mission at another branch. Perhaps he is required to stay at his new branch... perhaps he is training new "New-Types."
