Super Robot Wars OG: Diorama
The story is set in a post-apocalyptic world where a mysterious phenomenon called the Diorama Effect has turned most of the Earth's surface into a barren wasteland. The only survivors are those who live in the few remaining cities protected by giant domes, or those who wander the ruins in search of resources and relics.
The protagonist is a teenager named Ryo Solmaz, who lives in Neo Nagoya, a large dome city. He is a fan of mecha anime and games, and dreams of piloting a real robot someday. One day, he finds a strange device in a junkyard, which turns out to be a control unit for a hidden underground facility. He activates it, hoping to find a robot inside, but instead he unleashes a horde of mechanical monsters that attack the city.
As he tries to escape, he is saved by a mysterious girl named Automatia, who claims to be a mecha musume android sent from the future to eliminate him. She says that she is the cause of the Diorama Effect, and that she must kill him before he prevents the final phase of the phenomenon, which will destroy the entire world. However, she also reveals that she has lost most of her memories and data, and that she is not sure if she is telling the truth or not.
Is she his enemy? Can he trust her?
This "game" has crossovers with: Asura Cryin', Kaitou Kiramekiman, and Vividred Operation.
But otherwise, all the characters are original.
