Earlier this summer, the second part of the second season has been scheduled with a July 6th, 2021 debut.
The anime adaptation of the manga That Time I Got Reincarnated as a Slime from Fuse and Mitz Vah got underway in Japan with its October 1st, 2018 premiere and we learned not long after that more was coming.
They’re intending to get it underway on August 24th, 2021 for the dub and are starting with episode 36.5 for it.
