Light novelist Tsuchiya Tsukasa has attended a Kadokawa Sneaker Bunko event
at UDX Theatre in Akibahara on December 8th and has guessed that 「？？？」 will be a Haruhi short short story. (Later he has said that it is not a settled matter, however.)
Since he has heard that Haruhi seems to be going to wear a gorgeous kimono in the short story in Haruhi Hyakka
, he has conjectured that the story will be set in the winter when she is a first-year student.
