At the end of the 20th century, when nuclear war is about to begin, I have crawled into the top floor of the tower apartment, and now I am making a "will DVD", a popular trend during this time. Meanwhile, a strange woman called Iris randomly enters the room. She asks me if l would like to buy a DVD she made of original written poems, called "1 GB WILL". I agree on the condition that I will buy it if she will have sex with me, and unexpectedly she agrees.I am surprised trying to read her DVD on a computer after the act. What is written at the beginning is the same as the will DVD I'm making. As soon as I discover that, the personal computer starts running by itself like crazy, and fragments of electronics scatter in the room.I faint and fall down on the sofa. When I wake up, I notice a woman sitting on the refrigerator looking down at me.When I look closely it seems to be Iris, but she says she is a self-styled "Tenshi(Angel)" "Denshi(Electron)" on the refrigerator. I realize she is not sitting, but slightly floating in the air.She begins to talk to me in a confused state: She tells me that a few months after I moved here, I jumped off my apartment balcony and I am dead already. She says that the nuclear war will start soon.While her absurd story goes on further, I need to know what is "real". I remember half a Coke that should be left in the refrigerator, and I crawl desperately across the floor, striking out at the refrigerator. But my struggle resulted in despair.Once I finally reach the refrigerator and open it, there is a new Coke, not the half-finished one I remember leaving there. In my unbearable feeling of emptiness, although neither perspective nor shape recognition collapses, memories and prospects disappear. I realize that all my consciousness is beginning to diverge from the world.And finally, it becomes impossible to grasp the structure of the world, or any sense of who or what I am.Chaos that would ensue for hundreds, or thousands, of years began.A short psycho novel that can be read in 15 minutes.※ "Giga" means Caricature in Japanese.※ This book contains 11 color images (illustrations).※ All proper noun used to refer to a real person and/or an organization imitating really exist, but it is the creator's creation.※ Is the author's recommendation BGM (or ending song) during reading about "Bloodstream" of "The Chainsmokers" or "Do not Do Anything" of "Nacho Sotomayor"?
