Riddle does not use any honorifics with Trey, Cater, Ace or Deuce.

Riddle also does not use any honorifics with any of the first-year or second-year students.
Riddle uses the “-senpai” honorific with the third-year students.
















Exception: Riddle typically uses “-senpai” with Leona, with the (thus far) one-time exception during Book 2 where he dropped the honorific from Leona’s name in the panic leading up to Leona’s overblot.
