Robot and Monster Girl finally return to Earth after nearly a year lost in the Flaxan Dimension, where a full millennium had passed for them, rejoining the Guardians of the Globe and opening the Robot Era.
Home Sweet Home is a major turning point in Earth's history in which Robot and Monster Girl escape the Flaxan Dimension and come home after roughly a year of Earth time, though a thousand years had passed for them within that realm. It counts as one of two events that begin the Robot Era, described as the golden age of Earth's civilization.
For over ten months the Global Defense Agency tries and fails to retrieve the pair. In early 2025, Cecil and D.A. Sinclair work in a secure lab, using experimental transdimensional portals to comb the multiverse for the Flaxan Dimension. Sinclair finally stabilizes a promising gateway, but rather than the lost allies, a tentacled beast lunges through and kills several soldiers before security subdues it. Judging the danger of opening unknown rifts too great, Cecil reluctantly ends the search and trusts that Robot and Monster Girl will find their own way back.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
In Home Sweet Home, Robot and Monster Girl finally return to Earth after nearly a year lost in the Flaxan Dimension, where a full millennium had passed for them, and they rejoin the Guardians of the Globe as adults.
Robot and Monster Girl were gone for roughly a year of Earth time, but within the Flaxan Dimension itself, a full thousand years passed for them.
No, despite over ten months of effort using experimental transdimensional portals led by Cecil Stedman and D.A. Sinclair, the Global Defense Agency failed to retrieve them, and Cecil ultimately trusted the pair to find their own way home.
When D.A. Sinclair stabilized a promising gateway, a tentacled beast lunged through instead of the lost allies and killed several soldiers before security subdued it, leading Cecil to end the search.
Home Sweet Home marks the start of the Robot Era, described as the golden age of Earth's civilization, once Robot and Monster Girl return and rejoin the Guardians of the Globe.
