Taka no Tsume 8: Yoshida-kun no Batten File

In 20th-century Yoshida Village, young Yoshida and his friends are playing in their secret base when two investigators suddenly arrive from the future. Mulder and Nascally of the World Federation Investigation Bureau's X Division are searching the past for a cursed videotape linked to bizarre incidents in their own era.

Yoshida joins the hunt, but the investigation refuses to stay on course. Unidentified creatures, mysterious ancient objects, aliens, and paranormal phenomena appear one after another, turning the search for a single tape into a sprawling childhood adventure where every strange detour might be the clue that saves the future.
