The Pleiades of the Seven Stars

"Union" is a once popular multiplayer online role-playing game. A team called "Pleiades" composed entirely of elementary school students is the overlord of the game and is invincible. However, an accident led to the death of one member of the team, Asahi (voiced by Riya Omori), which led to the dissolution of the Pleiades cluster and the game was forced to go offline. Years have passed in the blink of an eye, and the former members of the Pleiades have now become high school students. At this time, a game called "Reunion" once again broke into people's sight. The former striker of the Subaru Star Cluster, Amaha Yosho (voiced by Kengo Takanashi), logged into the game and unexpectedly discovered the figure of Asahi Hime in the game. Is what standing in front of him just a fragment of information or the ghost of his childhood sweetheart? In order to fulfill a childhood promise, the Pleiades cluster reunited.
