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


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?

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](https://www.samuel-

episodes, but differ on how many episodes Yukaku-hen will have (13 or more).
