And Again We Are Going Up (2019)

Overview

Kaede, Ryota, Mana, Asahi, Haruka, Soshi, and Tatsumi were friends in high school. When they turned 22 years old, the six of them get together to visit their alma mater. They stop by the library and find a book on séance techniques, and then begin to perform "Kagome" necromancy. Kaede, who is the least enthusiastic, has a secret between her and Tatsumi, who died before graduation.
