November 22, 2010. Monday. Ten missiles hit the territory of Japan. However, this unprecedented terrorist act, later to be known as "Careless Monday" apparently did not cause any victims, and was soon forgotten by almost everyone.
Then, 3 months later... Saki Morimi is a young woman currently in the United States of America on her graduation trip. But just when she is in front of the White House, Washington DC, she gets into trouble, and only the unexpected intervention of one of her fellow countrymen saves her day.
However, this man, who introduces himself as Akira Takizawa, is a complete mystery. First of all, he appears to have lost his memory. Secondly, he is stark naked, except for the gun he holds in one hand, and the mobile phone he's grabbing with the other hand. A phone that is charged with 8,200,000,000 yen in digital cash.
Who is Akira Takizawa? What are the secrets behind his extraordinary mobile phone? What got lost with his vanished memory?
