In this episode even the script comments on some really blatant subtext, the Gale prove they really are a dysfunctional family, the ‘aliens’ show up in person and one of the BGMs should sound familiar to Brygar fans.
Notes for this episode.
The artificial planet Ofus seems to be based on a mix of Dejima, an artificial island off Nagasaki, and the ports opened to foreign trade by the Harris Treaty of 1858 (Kanagawa, Kobe, Nagasaki, Niigata, and Yokohama).
Ozma Drago is based on Sakamoto Ryouma who was a player in the Anti-Bakufu movements who turns up in Japanese popculture a lot.
In other news the new J9 project is to be called Ginga Jinpu (Kamikaze) Jinraiger, same writer as the original trilogy.
