The series will get in Super Robot Wars
And it will be connected to either Aura Battler Dunbine, Magic Knight Rayearth or Knight's & Magic with Leon's Arroganz while Luxion is his sub-pilot. Or any other series that features an isekai with robots.When it does get in Super Robot Wars, it will adapt events that happen in volume 3.
The anime ended with Leon taking on the hastily built mech that the five built. Meanwhile, volume 3 has a much better Final Boss fight where Leon gets rematch against the Deadly Upgrade Black Knight and the Weiss ship as an escort mission to ensure that Olivia, Angelica, and Marie survive before the royal ship gets destroyed in the end.
