After seeing a teenager looking at the window of Classroom 1, Vanir mocked him, "You there with the nasty stink face. While I do enjoy watching your eyes bulge out of your head in astonishment.  I would greatly appreciate if you wouldn't disrupt my instruction."

During field day, Vanir and the three other teachers (including Roswaal and Mr. Rerugen) competed against the students of Class 1 and Class 2 (including Kazuma and the same teenage boy whom he saw the previous day).
