Akihabara@DEEP. It is an enterprise that is small but elite and organized by the legendary otaku of Akihabara. Soon, they'll be dragged into the struggle for supremacy in a world of information technology. A battle is about to begin in the Akihabara district for the future of the industry.

A week ago Akihabara@deep found out that the big IT company, Digital Capinet, will be releasing a similar product to their "BLUE." Although Akihabara@deep is a small company, they still developed it before Digital Capinet. Akihabara@deep only has three days left, and he must find "Yui" in Aquila, the online game, to complete "BLUE"...

On a stage of raw bones and rotten skulls, two brothers are prepared to battle one another. The first is Harara, who desires nothing more than to expunge Earth of its humanity, while Kakugo, encased in "living body armor," defends Earth. Both are masters of the Zero Form martial art - who will survive until the very end?

Fortified Armor Shell Zero and Kakugo have defeated the first Tactical Fiend, but Harara has even more sinister plans in store for his brother. An army of bizarre monstrosities are at Harara's disposal to wreak havoc and destroy all that stands between them and Kakugo.

Kakugo is fully prepared to die. The battle that awaits him is with a warrior far more powerful than any that came before him. In his foe’s flesh are far more Zero Form Balls than Kakugo or his brother, and he was trained by Kakugo's own father. How can Kakugo possibly survive?

Kakugo finds himself in a bloody battle with Tsumiko, his own sweetheart. Unable to fight back, Kakugo is captured and mutated into a Tactical Fiend himself! Kakugo's next opponent is the mighty Bolt, a soldier who fights in a fortified armored shell of his own named Shin. How will will Kakugo stand up to this new armor, which is not only invulnerable, but also extra shiny?

Kakugo faces Bolt, a warrior protected by the Fortified Armor Shell. Shin and the souls of four hundred warriors who died facing Kakugo in battle. Kakugo's Fortified Armor Shell Zero is still out of commission, so Kakugo does what he must to win.
