What’s this animation movie called..?

It’s a school girl that came to a shrine I think, sat on stairs and when she dropped her bracelet, she saw a small hang grabbed it, followed it to a another place where I think those are lost items, and scents she’s human the little creature boy gave her a pig mask for a disguise. I can’t find the name of that movie.. xc
