A mysterious band of light appears in the sky, which is revealed to be a faint remnant of the Pleiadian's spaceship that is slowly materializing. After recovering a fragment and returning it to the clubroom, Subaru discovers it to be a fragment that the cloaked boy had captured, using it to track the girls towards their base. Trapped inside the school by the boy's magic, which locks the others out, Subaru flees from the cloaked boy and comes across the greenhouse, where Minato reacts strangely to the earring that emerged from the fragment. Minato sends Subaru further into the garden to a door, which opens up the observatory doors, allowing the other girls to enter the school and pursue the caped boy, who brings the school into space in order to fight against them.
