Somewhere in Country X

A man in his pajamas was forced to kneel in front of a man with a horrifyingly ferocious and almost inhuman eyes inside a certain mansion's master's room. The man in pajamas was no other than Country X's former president, the founder and still the current leader of the underground organization, Blackleaf.

"Z-z-zero?" he said as his mouth trembled the moment he saw who just sneaked like a quiet wind appearing out of nowhere inside his supposedly perfectly secured villa.

"Long time no see, Mr. Black." Zaki said in a voice completely devoid of any human emotion. Causing the old man trembled in fear even more.

"H-h-how did you get"

"Did you really think you can hide from us? Even if you hid yourself under the deepest ground on Earth, Sei will always find you. And once Sei spots your vulnerable ass, even if you surround yourself with thousands of your men, I will always get passed them." Zaki said as he walked slowly like a lion while he looks down on a trembling rat before him.

"Why so surprised? Did you forget how your men created me? Aren't we the monsters that you were always dreaming of?" Zaki continued when for some reason, the man suddenly looked up and started talking.

"Z-zero If you come to me. I can give you everything. Money, freedom, everything. Don't be blind, that monster Sei is just treating you as his loyal dog and nothing more. Can't you see he's just using you?" The man said, thinking that he could change his mind. However, contrary to what he expects, Zaki just smirked even more evilly.

"His loyal dog, huh" Zaki uttered as he smiled again before he squatted in front of the kneeling man as he continued. "Did you really think I'm idiotic enough to even consider a word from you? Listen... Even if what you're saying is true, I don't mind it at all. That moment he took me out with him, my life is already in his hand, so don't even think about it, you understand?"

"Zero, listen"

"Shut your mouth. Do you want to know why you're still alive up to these day? It's because Sei only sees you as a little dust not worthy of his energy to waste with. However, too bad because he finally found a reason to seek you So if you still wanted to see the sun again, tell me the truth. What happened to the town of Zemei?" he asked and the man's eyes widened with fear and he immediately began to beg.

"Z-zero believe me. Even us don't have any idea on what happened that day. If you don't believe me, Sei can take control of the whole country's information system. We know nothing about what happened that's why we could only blame the disaster to him." He said and a merciless blow immediately landed on his face.

Meanwhile, Sei who was listening to their conversation the whole time in front of his computer clenched his fist tight as he talked.

"Zaki Don't kill him. We still need him. Come back now." He said before he leaned his head on his hand. His face was dark and unpleasant. It was because the case seemed to be much deeply complicated and mysterious than he thought. What the man said just confirmed what Sei already found, that Country X and the Blackleaf knows nothing about what happened that day. However, not even a little discouragement appeared in his eyes, instead, the mysteriousness of the case strangely lit a fire in Sei's interest. It was because this is the first case he actually failed to exploit in his first attempt.

Hours later, Zaki returned with a disappointed look in his face.

"Ahh that rat really is useless. What to do now Sei? It seems like this one is not easy at all." He said but to his surprise, Sei's eyes were glimmering with a hint of strong interest. Causing him to just sigh as he sat beside him. It was because it's been forever since something, apart of course anything about his wife, has manage to catch his interest.

"Oi Sei What are you planning to do?" Zaki asked again when Sei finally snapped and looked at him.

"We're going home." He said and Zaki immediately stood noisily as he raised his hands.

"Ahh finally, it's been three weeks. I want to eat Young Miss' food." Zaki said energetically when suddenly Sei patted Zaki's shoulder. Causing him to turned towards him with puzzled look.

"You are not my dog or anything like that." Sei said before he just walked passed him. Leaving Zaki speechless for a while before a wide mischievous smile carved in his face.

"Hmm? What's this Sei? You're actually bothered with what that damn rat said?" Zaki asked happily as he catches up with him, and grinning like an annoying cat.

"Not that. It's because no matter how I see it, you don't look like a dog at all. And you're not obedient at all." Sei nonchalantly said when Zaki immediately retorted.

"Huh? I only disobey when I know your order is risky you know?!"

he said but Sei ignored him as he continued walking away.

"Hey, don't ignore me."
