Though I have a feeling if Demon Slayer Infinite Castle movie trilogy does as well as Mugen Train. We going to see key battles and arcs get a movie as well as a mini-season. Especially for big budget anime

I am perfectly fine with this TBH It's clearly a working model that allows studios to have more time and resources to animate really killer scenes. And it's honestly pretty cool meeting other anime fans in public. I have had pretty good success with it!
