15 years after the 2nd impact, Tokyo has been flooded so the people who lived in Tokyo moved to Tokyo 3. Reimu, who entered the real world from Gensokyo, wondered in her mind:"How long was I gone? there's no way Tokyo could be flooded by now." and then Marisa asked "what is this place? swim city?" and then Reimu turned around and said
"its a long story. I lived there once but then it got flooded. Its amazing how many years have passed since I left this area."
"Oh uh... don't worry. after all at least you have your friends back at Gensokyo right?"
"Yeah but i'm was starting to miss the real world which explains why i got here. I wanted real action. I mean remember that one thing with the basketball hoops, the basketball shoes and the 50 pounds of cheesecake?"
"No."
"I do and it happened in real life."
Suddenly and unexpectedly, something huge jumped out of the water.
"ITS GODZILLA!"
"OK so technically Godzilla is a fictional monster right?"
But it isnt Godzilla. It was a monster with dark green skin, Bony shoulders, a bird like mask for a face, limbs so skinny it would have been impossible to support its weight and a rib cage that surrounds a red sphere.
"Hey big ugly, LETS FIGHT!" said Reimu as she casts "dancing yin yang orbs" at it. The monster blinks in confusion at the orbs. The yin yang orbs dance around the monster until one hits the red orb on the monsters rib cage. First, the orb explodes and then the monster itself. It rains blood as a rainbow appears in the sky and there was a gigantic glowing cross where the monster was standing before death.
Meanwhile in Gensokyo, Mima and Cirno were watching the events on TV.
"Why do people watch this?"
"Because it is action Cirno."
"But what if one of them dies? im gonna be sick"
Cirno then runs to the bathroom to hurl while Mima grabs a bowl of popcorn.
Back in the real world...
"My Reimu, I think this real world action is better than you said."
"Heh thanks."
Meanwhile, somewhere else in the real world...
"Earlier than they said huh?"
"Yes... Reimu is back"
