Introduction to the World

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 Zero hadn't spoken a word since they left the huge lab surrounded with big walls. However, as soon as he stepped outside the huge gate, Zero's eyes widened, and his mouth hung agape. He was obviously surprised by the vast open blue skies and the various architectural buildings extending out to the horizon as far has he could see. 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 been exposed to the outside world.
