I've seen that the Kimetsu no Yaiba movie Mugen Ressha-hen is being adapted into episodes. It's been 3 so far with a 4th coming, and it doesn't look like it's going to stop there. I've seen other animes that have adapted movies into 4 episodes miniseries, but not much more than that, and this looks like it's going to continue. On other hand, it's hard to think they can adapt a movie into a whole season. My question is,

Is this adaptation of this Kimetsu no Yaiba movie Mugen Ressha-hen a mini series apart, or is this going to be the second season of the Kimetsu no Yaiba anime?

According to here:


So yes, Mugen Ressha-hen is remade as part of the 2nd series which consists of Mugen Ressha-hen + Yukaku-hen.

Several sources say (e.g. here) that Mugen Ressha-hen will be 7 episodes, but differ on how many episodes Yukaku-hen will have (13 or more).


Mugen Train Arc of Kimetsu No Yaiba is a part of the second season of KNY. It is the same as the movie but with some additional scenes. This arc will be of 7 episodes as per some sources. And the District Arc will air in December. This arc will be of 10 episodes.

Hope it helps!
