Corpse Party (2021)

A friendship ritual gone awry transports high school student Ayumi Shinozaki and her friends to an alternate reality version of a tragedy-stricken institution that stood on the site of their own school long ago. As the vengeful spirits of elementary school students threaten their lives and their sanity, their only hope of survival–much less escape–is to uncover the chilling details surrounding the murders of those trapped before them.
