Hiya - trying to think of this movie, it was part of like the 2010s Ghibli-like movies. Its about two normal teenagers (perhaps kids) getting accidentally wrapped up in an adventure that takes them
underground and into another world. One of the people they are with is an older man, who i believe betrays them. Its very Mononoke vibes, very pretty, i believe there are animals with like - crystals growing out of them.
