SYNOPSIS: Thirteen Card Decks were created for thirteen Kamen Riders. They make Contracts with monsters from the mysterious Mirror World, a parallel dimension opposite to our own in which only the Kamen Riders can exist. The Riders draw on their monsters' strength in exchange for feeding them the life force of the creatures they destroy. The creator of the Advent Cards has only one rule: that there can be only one Kamen Rider. The others must be killed, and the sole victor will be granted a single wish, which leads to a conflict known as the Rider War.

Wait, the prompt asks for "Kamen Rider Season 12".
The SYNOPSIS provided describes the "Rider War" mechanic (Card Decks, Mirror World, etc.). This description actually belongs to Kamen Rider Ryuki, but the prompt asks me to treat it as the synopsis for "Kamen Rider Season 12".
I must follow the prompt's instruction: "For the series 'Kamen Rider' Season 12, using ONLY the synopsis and sources below..."
The synopsis provided is the only source for the plot of "Season 12".
Overview Construction (Target 160-220 words):
The narrative of this season centers on the existence of thirteen Card Decks, which were specifically created for thirteen Kamen Riders. These Riders enter into contracts with various monsters originating from the Mirror World, a mysterious parallel dimension that exists opposite to the human world. Within this Mirror World, only the Kamen Riders are capable of existing. To utilize their power, the Riders draw upon the strength of their contracted monsters, providing them with the life force of the creatures they destroy in exchange for this strength. The fundamental conflict of the season is driven by the creator of the Advent Cards, who has established a singular rule: there can only be one Kamen Rider.
