It was autumn when they granted Sei's request to take Zero out of the lab. Of course, the organization asked Sei to create an advance spying malware in exchange.

After he succeeded, Sei then took him out and to everyone's surprise, the usual wild and untamed boy just followed Sei like an obedient pet.

The boy never talked at all since they left the huge lab surrounded with big walls. However, as soon as he stepped outside the huge gate, Zero's eyes widened. He was obviously being surprised with the things he was seeing. Sei wasn't surprised with his reaction at all, it was because he knew that the boy stayed inside the lab for nine years and never had a peek to the outside world.

Until the two young boys were walking quietly on the road side as leaves of maple trees were falling over them when suddenly, Sei stopped. The boy behind him immediately halted as well, as though he was a robot following Sei's every move.

Sei raised his hand and caught a bright red leaf in his hand. He quietly stared at it for a long while before he turned towards the boy behind him.

Combining the the beginning of his codename 'Z' and the Japanese word 'aki' which means Autumn, Sei created a name for him.

"From now on, your name is Zaki," he said and the boy just blinked twice before he obediently nodded at him.

Since then, Zaki stuck beside Sei in everywhere he goes. Both of them stayed inside the house of hackers, and as time goes by, Zaki continued learning everything to become a normal human being. However, Sei on the other hand continued being pressured by the organization to perform high level cyber-crimes under the name of blackleaf, promising him that one day, they will release his mother. Sei of course knew that their promises were mere lies.

They also never let Sei touch any computer or cellphone alone. He was only allowed to touch them when he's under extreme surveillance.

Thus, for a couple of years, Sei never once disobeyed the organization's orders. He did everything to gain their trust, acting like he finally accepted being their loyal dog.

And due to his loyalty, the Blackleaf's leader sent him back to Country H, giving him a high profile mission, to shut down Country H's military bases for the planned all-out attack of the red rebels in the country's capital.

Until a year later, the day of the planned attack finally came. The twelve-years-old boy Sei was then heavily guarded, and the rebels threatened him that if he fails to do his mission, they will kill his beloved mother.

The rebels also imprisoned Zaki along with his mother, causing Sei to just abide and do the job without batting an eye.

Thus, that day, the new world's most terrifying hacker was introduced to the world. His success in shutting down the military bases made the red rebels successful infiltration to the capital possible.

However, nobody knew other than Zaki that everything that was happening ever since he went and took Zaki out of the lab were already foreseen by Sei. He anticipated the flow of events and exploited the Blackleaf and Red rebel plans to its very roots. No one knew that he purposely rode along with the red rebel's plans for the sake of their escape. Thus, while the red rebels were attacking the capital, in the middle of war and chaos, and using Zaki's combat ability and Sei's perfect escape plan, the three of them successfully escaped without any scratch.
