Astrom

Astrom was the homeworld of Princess Laiina and Knuckle.

History
It hosted the medal of Raging Arrow, from which a Karakuri system was developed for this planet. It was later destroyed by Sandaaru after he forcefully obtained the medal.

Technology
Astrom seemed to have an advanced Karakuri system, as their Tri-Condor was not only used as a spaceship, but it could also perfectly combine Earth's 3 Karakuri Giants into one without any modifications, something Oboro Hinata struggled to do for many episodes with her own Tri-Condor.
