Even though the modernized helicopter successfully kept up with Kusanagi Ritsuko's car, it was obvious that the children of the Sixth Destroyer Fleet couldn't rely on their short legs to catch up on foot.
However, Akatsuki and the others' goal in tailing Kusanagi Ritsuko was merely to gather intelligence, so keeping pace wasn't essential. As Rai piloted the helicopter to continue tracking Kusanagi Ritsuko, the four little girls simply followed unhurriedly by taking buses and subways.
Rai held an operating console resembling a model remote control, complete with a small screen displaying the helicopter's feed. At this moment, the footage showed Kusanagi Ritsuko's van stopping in front of an unfinished building.
"They've stopped!" Rai exclaimed upon seeing the scene, quickly shouting to alert the others. Her three sisters rushed over to peer at the screen on the console.
