From the creator's homepage:
Mahou Shoujou Kishu Apocalypse 4ever är the first game that uses the System7 platform, and is a future part of GIRLS, when it has migrated to System7
The End of Days is here. There's just one proble,: The End of Days have beeen globalized, so the Last Battle won't just happen at Armageddon, it will happen everywhere!
And if that wasn't enough, the daemons is a bunch of goddamn assholes, so they will cheat. And the armies of Heaven isn't exactly a bunch of angels either, except literally. BOTH sides wil cheat. And it's here that the four Horsemen of the Apocalypse come in – they job is to see that no side breaks the rules. Although they're under-manned, the Horsemen have expanded. They've started a franchise!
The only thing you need to be a franchise is four persons with horses, and who have the wish to shoulder the responsibility to keep order in the armies of Heaven and Hell. In exchange, the franchisers will get access to cool super powers.
Someone messed up the demography. The majority of horse-owning persons who wanted super powers happened to be teenage girls who had read too much shojo manga.
How's that for a catastrophe?
Mahou shouho Kishu Apocalypse 4ever is one of Rävsvans publisher's entries to Troberg's Dogma contest 2005.
