In an unknown place, a man was in an office.

"Boss! We have a problem!" Another man comes to the office.

"What is it?" His face was hiding in the shadows. "What is the problem?"

"Well…" He hesitates before talking. "Our secrets… someone knows our secrets…" The boss was surprised to hear it. "Someone was spying us… It will be troublesome if they know the secret of our power! What do we have to do? Nero-san?"

"Don't do anything, I will tell the big boss, then, we will move."

…

"Hey sis, where are you going?" Xeln asked his sister. "You promised me that you will help me on doing my homework."

"When will you learn? I told you that you have to try then come to me." Nosaru answered.

"Eh?" Xeln said sadly. "I wish I can grow up so I can go on a date like you, big sis."

"D… Date?" She shocked at his words. "I am going to met Jim and Shamal, but this is not a date!"

"Sister, I am curious about something." Nosaru looked to him with confused eyes. "You don't have any girlfriend, aren't you?"

Shit! He has a point! She leaves the house without answering him.

…

"What did you say?" A man flips the table. "Do you understand our situation Nero? The secret of one of the most powerful weapons in the world is in the hands of a weak man!"

"What do we have to do?" Nero asked calmly. "Boss, are you going to kill him?"

"Not me." The boss answered. "Send a D.O.N member."

"What about Calore?" He says. "He can end this in a second."

"If you want to kill him in a second, why don't you choose me? A red haired man appears.

"When did you come? Speed? Nero asked him. "I thought you were in mission."

"What? You don't want to see your big brother or what? Nero?"

"Stop you two!" The boss ordered them. "Calore will go, and kill all his family. All those who haves the name Koketé should die! Do you understand? Hell Brothers?

"Yes sir!"

…

"A mission?" A bald man was in front of Nero. "That's a good think you know." A devilish smile appears on his face. "So, what do I have to do? Nero-kun?"

"Kill a family named Koketé, which is your mission.

"Hah? That's not cool! I want something better!"

"Stop crying like a baby!"

"I don't want that stupid mission! YOU take care of it

-Well, you can burn their flesh, so nothing stay, just their bone.

-Oh, that will sound fun. What about their house?

-Burn every thing you want, and, don't leave anything, just the dust.

- Interesting.

"How cruel can you be? That's why… They call the must dangerous members of the family… D.O.N … And I am one of them… The D and O mean Diablo…The N is Nero… This is the name of the family who kills anyone without hesitation… The DIABLO NERO FAMILY."
