21st century Goguryeo - Chapter 230

When other people experience a body transformation, it is inevitably either male to female or female to male.

Me? I wake up to find myself transformed into two different bodies.

Both a male body and a female body, one conscience operating two bodies, all sorts of embarrassing moments.

Walking together normally makes other people think that I am sweethearts with my other-self, such sadness.

Also, the entire business of a hero rescuing the beautiful maiden, I call Bull.

I get slashed by a sword and my female body gets abducted, and he wants me to thank him?!?! Can it be less of a tragedy?

- Description from Novelupdates

Due to the whims of a higher-dimensional being called “The One”, the World of Terra ushered in a Monthly Apocalypse World Update Era.Every month, the World will draw a random monthly apocalypse world update theme, and the world will transform depending on what update theme has been drawn.Starting with a Zombie Apocalypse World theme, The World of Terra became infested with zombies!As a transmigrator, Zayne Voss, who thought he was living in a normal modern world, was caught up in this madness.Fortunately, he awakened the innate ???-rank talent, the Doomsday Life Simulator System![The Doomsday Life Simulator System allows the host to simulate your future and life in a given doomsday scenario.][For example, the simulator will randomly draw a doomsday scenario, and one of them might be a zombie apocalypse scenario. In that case, the host can experience life in a zombie apocalypse world.][Of course, it's not limited to that, as there are also different kinds of doomsday scenarios like the Helios Extinction Event, where the sun explodes and humanity faces such a world-ending scenario.][Not all doomsday scenarios are winnable and survivable, as some can be a dead end. However, your goal is not to win but to survive as long as possible and attain as many achievements as possible.][The longer you survive and the more you accomplish within that doomsday scenario, the higher your score will be. The higher the score, the greater the rewards you'll receive.][The rewards you can receive are mostly related to the power, skill, experiences, and talent that you possessed before the doomsday life simulation ended. They will be brought back to the real world so the host can gain power from doing life simulations.]-Ding![The host can choose one doomsday scenario from four of the following:][A. Helios Extinction Event][B. AI Singularity Rebellion][C. Global Ocean Survival][D. Acid Rain Catastrophe]Drawing the doomsday scenario called “Global Ocean Survival,” where everyone started with a wooden raft on a vast ocean, Zayne grinded in the doomsday simulation to become stronger in the real world!While everyone was still running away from zombies, Zayne had already eaten a Fairy Fruit from the Global Ocean Survival World and killed all the zombies around him!

A series of short stories in the world of Toaru Majutsu no Index organized into chapters featuring Kanzaki Kaori as the protagonist, going around the world and space doing missions for the Church of Necessary Evil, however, there is more than meets the eye as each incident is connected.

One chapter was bundled with each limited edition release of the Toaru Kagaku no Railgun anime DVD and BDs, with all of them together being equivalent to a single normal Toaru Majutsu no Index volume
