If Undertale's fights were to get Adapted and Animated by An Anime Studio. What Studio do you think should do The Job?

I say fights specifically since I don't think Undertale would ever get adapted into a full on series or movie. Especially with its things like choice and and such. However no one said The Fights were impossible? Right?

So why not make it a boss rush like show or movie that shows some cool ass that happens through out The Game. in all Routes,

And since Anime Studios do adapt their fights into full on movies.. like what Mappa did with Sukuna vs Mahoraga. they could do the same with this Undertale Animated Boss Rush thing and maybe turn it into a Movie.
