There's a short anime series called "Mononoke" (not Princess Mononoke, just "Mononoke") that is ridiculously good. It has 12 episodes and has an AWESOME animation style. It's seriously fkn great. I don't really know where you can watch it, but I guess it's available on Crunchyroll or that kind of streaming platforms. If you can't check that one out, then I'll suggest you to watch Infinity Train, it's made by Cartoon Network and has four seasons.
