The latest issue of Shonen Sunday has confirmed that the anime adaptation of the “Crimson School Trip” case will air as two 1-hour specials on the 5th and 12th of January, 2019. This case marked the 1000th chapter in the original manga in August of last year.
A leak from the issue a few days ago suggested those dates for the case, but now the schedule has been officially confirmed, as well as the episodes being 1-hour specials. These will be the first extended-length episodes since the 2-part anime-original filler episodes that kicked off 2016.
The episode numbers have not yet been confirmed, and they likely will not be until December. Still, it should be a relief to many that we now have a timetable for when what might be the most highly anticipated case of the last few years will come to the anime.
