At the end of "In Another World with My Smartphone" Season 1, there is a major reveal about Professor Regina Babylon of Touya's new world creating nine female humanoid robots around 5,000 years ago. Regina was prophetic and saw that Touya would one day appear and have nine wives, and so she split apart her own consciousness and broke up the Babylon Kingdom into nine parts, placing them into the robots for Touya to find in the future. Therefore, Touya must go through a test to see if he is compatible with each of the robots, which would allow him full control over the Kingdom of Babylon.
But the end of the season also hints at the introduction of a major villain from the light novel series called Fraze, a group that travels to Touya's world through a part of the inter-dimensional boundary that is vulnerable and breaking down. The Fraze have similar powers to Touya, and so Regina creates mecha weapons for Touya and the girls to use to fight them off. As you can see, the story can get a little confusing and involved, but rest assured that there will be plenty of magic, battles, and grand adventures for Touya and the others in "In Another World with My Smartphone" Season 2.
