The year 851…
The Titan threat has not diminished at all. Wall Maria is still lost, and Wall Rose has held on as long as it can. Even with Eren Jaeger's power, humanity's hope dwindles. The time for following military strategies is over, and dawn has broken for new, wild ideas. There is nothing left to lose, after all.
Three brave soldiers have taken on one such idea. Three brave soldiers…and a whole lot of crazy, rabid, and horny fangirls. That's right; the time has come for Mikasa, Levi, and Hanji to impregnate every last fangirl on Earth!
The year 852: nine months later…
One after another, for days on end, hundreds of thousands of young ladies are going into labor. Their shouts of pain and obscenities can be heard all the way to Wall Sina. Time and time again, a new baby is born into this world.
The year 852: a few days later…
The babies born of Mikasa and Levi are already equipped. Having been birthed with swords and 3D Maneuver Gear, many have already run on ahead and taken out those Titans within Wall Maria. Within a matter of days, humanity had retaken all land lost to them those seven years ago.
Now the legion of super-babies stands ready for its greatest mission yet: killing all Titans and retaking everything humanity has ever lost! Equipped with the finest humanity can offer, the super-babies charge out into the world. Into the lands barely known by those alive today. It is a week before they are seen again, and in that time not a single Titan is spotted by the Garrison standing guard upon the walls.
The babies return. Their numbers have not shrunken by even one. The black haired babies raise their swords high, and humanity cheers. The babies have done it! Those born from Mikasa and Levi have accomplished what humans have been dreaming of since the Titan threat spawned over a hundred years ago! Earth is safe for humans once again! Wall Maria no longer marks humankind's boundaries!
The last of the Titans are still under close watch. The babies born of Hanji keep them under wraps, hugging and snuggling and talking to and adoring them to the very end. No one kills them, as no one can bring themselves to take away a baby's favorite plaything.
Finally, the world…is at peace…
