It also explores her interactions with the rest of the Idols, her efforts to fit in, and ultimately, the truth about her forgotten past.

This so-called "Topless" is a true space monster, as Lal'C learns when she witnesses its vicious attacks against her comrades and, horrified, asks Dix-Neuf (her Buster Machine) what this creature might be.

However, Lal'C and the Fraternity find themselves useless during this time, and one of the Topless is permanently put out of commission when he finally reaches his age.

The Space Monster warps closer to Earth, and Nono suddenly departs with the Solar Defence Force, seemingly vanishing from the system.

Meanwhile, Lal'C, for the first time, delves into Nono's past; how she learned to idolize "Nonoriri" and the man who found her in the depths of Space.

She and the remainder of the Topless prepare for the Space Monster's arrival and the timely intervention of Nono, who now becomes the mega android DieBuster.

Just as she is about to land a finishing blow using Douze-Mille's reformed components as a Buster Machine, her Topless powers suddenly expire.

However, in the wake of their battle, the black hole tears open due to the Space Monster's death.

Nono and Lal'C share one last moment, their hopes, dreams, and futures if they had survived, and Nono finally gives Lal'C a piece of her generator, or singularity, in the form of an origami crane, before using the remnants of the Alternate Buster Machines that comprised "DieBuster" to warp the black hole and herself away from earth.
