Both men wheel to face each other, back up, get back into the stance.

"Emotional intensity" doesn't convey the half of it, of course. It is the kind of coarse and disappointing translation that makes the dismembered bodies of samurai warriors spin in their graves. The word "zanshin" is larded down with a lot of other folderol that you have to be Nipponese to understand.

And Hiro thinks, frankly, that most of it is pseudomystical crap, on the same level as his old high school football coach exhorting his men to play at 110 percent.

The businessman makes another attack. This one is pretty straightforward: a quick shuffling approach and then a snapping cut in the direction of Hiro's ribcage. Hiro parries it.

Now Hiro knows something about this businessman, namely, that like most Nipponese sword fighters, all he knows is kendo.

Kendo is to real samurai sword fighting what fencing is to real swashbuckling: an attempt to take a highly disorganized, chaotic, violent, and brutal conflict and turn it into a cute game. As in fencing, you're only supposed to attack certain parts of the body - the parts that are protected by armor. As in fencing, you're not allowed to kick your opponent in the kneecaps or break a chair over his head. And the judging is totally subjective. In kendo, you can get a good solid hit on your opponent and still not get credit for it, because the judges feel you didn't possess the right amount of zanshin.

Hiro doesn't have any zanshin at all. He just wants this over with. The next time the businessman sets up his ear-splitting screech and shuffles toward Hiro, cutting and snapping his blade, Hiro parries the attack, turns around, and cuts both of his legs off just above the knees.

The businessman collapses to the floor.

It takes a lot of practice to make your avatar move through the Metaverse like a real person. When your avatar has just lost its legs, all that skill goes out the window.

"Well, land sakes!" Hiro says. "Lookee here!" He whips his blade sideways, cutting off both of the businessman's forearms, causing the sword to clatter onto the floor.

"Better fire up the ol' barbecue, Jemima!" Hiro continues, whipping the sword around sideways, cutting the businessman's body in half just above the navel. Then he leans down so he's looking right into the businessman's face. "Didn't anyone tell you," he says, losing the dialect, "that I was a hacker?"

Then he hacks the guy's head off. It falls to the floor, does a half-roll, and comes to rest staring straight up at the ceiling. So Hiro steps back a couple of paces and mumbles, "Safe."

A largish safe, about a meter on a side, materializes just below the ceiling, plummets, and lands directly on the businessman's head. The impact drives both the safe and the head straight down through the floor of The Black Sun, leaving a square hole in the floor, exposing the tunnel system underneath. The rest of the dismembered body is still strewn around the floor.

At this moment, a Nipponese businessman somewhere, in a nice hotel in London or an office in Tokyo or even in the first-class lounge of the LATH, the Los Angeles/Tokyo Hypersonic, is sitting in front of his computer, red-faced and sweating, looking at The Black Sun Hall of Fame. He has been cut off from contact with The Black Sun itself, disconnected as it were from the Metaverse, and is just seeing a two-dimensional display. The top ten swordsmen of all time are shown along with their photographs. Beneath is a scrolling list of numbers and names, starting with #11. He can scroll down the list if he wants to find his own ranking. The screen helpfully informs him that he is currently ranked number 863 out of 890 people who have ever participated in a sword fight in The Black Sun.

Number One, the name and the photograph on the top of the list, belongs to Hiroaki Protagonist.

Ng Security Industries Semi-Autonomous Guard Unit #A-367 lives in a pleasant black-and-white Metaverse where porterhouse steaks grow on trees, dangling at head level from low branches, and blood-drenched Frisbees fly through the crisp, cool air for no reason at all, until you catch them.

He has a little yard all to himself. It has a fence around it. He knows he can't jump over the fence. He's never actually tried to jump it, because he knows be can't. He doesn't go into the yard unless he has to. It's hot out there.

He has an important job: Protect the yard. Sometimes people come in and out of the yard. Most of the time, they are good people, and he doesn't bother them. He doesn't know why they are good people. He just knows it. Sometimes they are bad people, and he has to do bad things to them to make them go away. This is fitting and proper.

Out in the world beyond his yard, there are other yards with other doggies just like him. These aren't nasty dogs. They are all his friends.

The closest neighbor doggie is far away, farther than he can see. But he can hear this doggie bark sometimes, when a bad person approaches his yard. He can hear other neighbor doggies, too, a whole pack of them stretching off into the distance, in all directions. He belongs to a big pack of nice doggies.

He and the other nice doggies bark whenever a stranger comes into their yard, or even near it. The stranger doesn't hear him, but all the other doggies in the pack do. If they live nearby, they get excited. They wake up and get ready to do bad things to that stranger if he should try to come into their yard.

When a neighbor doggie barks at a stranger, pictures and sounds and smells come into his mind along with the bark. He suddenly knows what that stranger looks like. What he smells like. How he sounds. Then, if that stranger should come anywhere near his yard, he will recognize him. He will help spread the bark along to other nice doggies so that the entire pack can all be prepared to fight the stranger.

Tonight, Semi-Autonomous Guard Unit #A-367 is barking. He is not just passing some other doggie's bark to the pack. He is barking because he feels very excited about things that are happening in his yard.

First, two people come in. This made him excited because they came in very fast. Their hearts are beating quickly and they are sweating and they smell scared. He looked at these two people to see if they were carrying bad things.

The little one is carrying things that are a little naughty, but not really bad. The big one is carrying some pretty bad things. But he knows, somehow, that the big one is okay. He belongs in this yard. He is not a stranger; he lives here. And the little one is his guest.

Still, he senses there is something exciting happening. He starts to bark. The people in the yard don't hear him barking. But all the other nice doggies in the pack, far away, hear him, and when they do, they see these two scared, nice people, smell them, and hear them.

Then more people come into his yard. They are also excited; he can hear their hearts beating. Saliva floods his mouth as he smells the hot salty blood pumping through their arteries. These people are excited and angry and just a little bit scared. They don't live here; they are strangers. He doesn't like strangers very much.

He looks at them and sees that they are carrying three revolvers, a .38 and two .357 magnums; that the .38 is loaded with hollow-points, one of the .357s is loaded with Teflon bullets and has also been cocked; and that the pump shotgun is loaded with buckshot and already has a shell chambered, plus four more shells in its magazine.

The things that the strangers are carrying are bad. Scary things. He gets excited. He gets angry. He gets a little bit scared, but he likes being scared, to him it is the same thing as being excited. Really, he has only two emotions: sleeping and adrenaline overdrive.
