As a nod to the original series, Megumi Han does the voice of Lalah Sune - a role made famous by her mother Keiko Han.
In episode 10; as Piyoko-chan walks through the field, he is shown singing the opening verse of 'Suna no Jûjika' by Takajin Yashiki, the song used at the end credit of Mobile Suit Gundam I (1981). However, it starts from the second verse.
