Saki's visit to the U.S. takes an odd turn when she meets Takizawa in front of the White House. He's naked and armed with a gun. He has no memory and may be a terrorist. And he's joining her on a flight to Japan.

Takizawa learns some unusual facts from Juiz: if he calls with a request, she'll make it happen - quickly. She also reveals that billions of yen are credited to the device - and Takizawa has to spend it.

At the shopping mall he calls home, Takizawa receives a violent visit from Kondo. Their next meeting goes just as poorly - the detective, bleeding in the street, reveals monstrous actions from Takizawa's past.

During a visit with the respected Dr. Hiura, Takizawa finally learns the rules, expectations, and penalties that come with the role of a Sele̤̣o. He also learns how impossibly difficult it's going to be to survive.

The beautiful and lethal Sele̤̣o Kuroha enters the picture. Meanwhile, the actions of two wildly different men - a stranger on the street and the Prime Minister of Japan - prove the extent of Takizawa's influence.

Osugi's life is on the line as Takizawa and the Johnny Hunter engage in a game of cat and mouse. When they finally meet face to face in Kuroha's exquisite lair, it becomes clear that nothing is as it seems.

Takizawa, Saki, and Micchon pay a visit to Panties, a reclusive geek who might have the skills to repair Kondo's phone. Across town, Osugi doesn't like what he finds after looking into Takizawa's identity.

After years on the fringe of society, Panties finds himself in the middle of a conspiracy when he successfully hacks into Kondo's phone and learns the truth behind Careless Monday.

After finding out Mr. Outside's true identity, Takizawa learns that those responsible for Careless Monday are planning an even greater attack - but the most disturbing revelation concerns his missing memories.

As missiles fill the skies above Japan once more, Takizawa must rush to prevent a catastrophe far greater than Careless Monday. He has the resources - but does he have enough time?
