Jizaburo Fuchiyama was a young boy enamored with the mistaken and idealized image of ninja. He was also an avid computer gamer. Online playing Master of the Shadow IV, his online avatar, Dark Warrior, had found a rich treasure and was zig-zagging back to the town to put it in the bank. But not being a very good computer gamer, Jizaburo's avatar was still of a low level and he had stumbled upon someone else's treasure that was gained from slaying a powerful monster. Dark Warrior was tracked down and found by the group of three high level avatars who had earned the treasure.

In the middle of the one-sided battle, Jizaburo had an extremely tortuous headache. And, when he opened his eyes again, he wondered if he was unconscious and dreaming. The landscape above which he flew was surreal. It seemed as if he were traveling through a pipe that branched frequently, and occasionally grew larger or smaller. All about him were sparkles that were in strings - the strings zipping through the pipe going in either the same or the opposite direction. He took a turn and then reached a glowing wall that opened briefly and allowed him through. Then he was into an enormous tube with not sparkling strings, but a pulsing river of brilliance that moved alternately one way and then the opposite way. It sucked him in and he felt... wonderful... wonderful and powerful. He flew through the stream despite its pulsatile flow and then went out another gate. That was enough. He decided that he wanted to wake up.

And he did. The headache this time was less painful and quicker. This time when he opened his eyes, he found himself leaning on a traffic signal. He still was in Japan, but from the signs, it seemed like he was several blocks away from home.

It took Jizaburo several months to learn how to control his strange and enjoyable powers. At first he just used them to alter points for his avatar in Master of the Shadow IV and then in other games. It was fun for a short time, then he became bored. He went on a crime spree, stealing electronic money then stealing real money using his abilities to bypass security measure. But eventually he was caught by Moon Warrior, Sunshine, and Hawk Rider II of the superhero team, House Hiuma.

His trial was held in a specially insulated room with battery powered lights. It seemed certain that he would be sent to a special prison. That was when Cyber One and a team of Dark Pool ninja broke into the room and took Jizaburo with them. Jizaburo has achieved his dream of becoming a ninja and the Dark Pool clan has attained an ideal ninja for their espionage missions.

Jizaburo lives to surf the internet. He is an information junkie, but never really uses the information for anything other than satisfying his thirst for web surfing. As a member of the Dark Pool ninja clan, he enjoys the thrill of the hunt - the hunt for restricted data, but detests combat.

"There is an entire other world wired in the fabric of this one."

eSpace is an uber with the ability to perceive electrical signals and rapidly decipher electronic data. He can alter his form from that of a physically tangible human being to electronic data. As electronic data he can travel via wire or even inhabit the body of an electrically-powered or electronically-controlled machine. All but immune to electricity, he is vulnerable to most other attacks and, in fact, must frequently recharge himself with electrical current. In most instances, he will grab data and run, but if he gets into a difficult situation, he will use his powers to use machines to aid his escape.

eSpace wears a typical black ninja igabakama. He would look like any other ninja but for the electric green lines that are scattered about his ninja suit that sometimes seeming to cross over each other, at other times running parallel. In leisure time, he appears to be a young Japanese man wearing jeans, sandals, and a T-shirt that bears the logo of some computer game.
