Manaka Sajyou, an existence connected to Akasha, is unable to experience phenomena like change and surprise, so she wishes to attempt to "dream." She sends her consciousness through the backside of the World, beyond the end of the world, and into different time and space. She ends up in a labyrinth, hosting a variant Holy Grail War, featuring four Servants and Masters attempting to reach the bottom. Manaka possesses the body of a Master who had summoned a female King Arthur. Saber interacts with Manaka, while Manaka and the original Master see each other when looking into a mirror.
Marimo Himenogi desperately wants to become an idol singer. When a local contest is announced, she begs her boyfriend, Ayumi to sing as her partner. Ayumi relents, and disguises himself as a girl so that he and Marimo can enter the singing competition. Surprisingly, they win and are signed to a recording contract as a new group called "Twinkle". Now they must keep their newfound fans from finding out that Ayumi is actually a boy.
The world ended on the day that the abnormally distorted, super-sized "Great Engine Clock" stood over the entire planet like a tombstone. The cyberzombies groaned and devoured the few lives that survived, and the last "people" left in the world were a young man named Kyrie and a young girl named Genevieve. The two continue their journey together and at cross-purposes, searching for the last sanctuary at the end of the dead world... A beautiful dystopia written by Hikaru Sakurai of the "Steampunk" series. (Source: Seikaisha, translated)

In future Japan, bigamy is legalized! Specifically, each person may legally marry two spouses, a simple legal change that brings up a lot of questions about serious romantic relationships. What would long-term relationships be like if they didn't remove you from the dating pool? Would people be more willing to commit if they knew they could also pick someone else later?
