The first manga-based canon episodes since July will air at the beginning of October.
The Detective Conan anime has announced the first case for October. The "Kendo Competition of Love and Mystery" will air in two parts starting with episode 916 on October 6th.
This marks the end of a two-month draught filled with anime originals. But, more importantly, this is finally the case that precedes Movie 21, "The Crimson Love Letter." Finally, those of you who only follow the anime and want to watch that movie without spoilers and with a full understanding of what is happening will be able to do so, a year and a half after its theatrical release.
Finally, I can add that movie, and the case, to the Detective Conan Important Episode List.
