The story begins in the KND moonbase's auditorium, where many KND operatives were watching from the stands as number 362 is preparing to make a speech to the hoard of operatives in the room.

Hello, my fellow operatives, you all know summer is almost over and that school will be coming upon us soon, Number 362 said as she hears sighs and grumbles of sadness from the crowd. But it's not all that bad, because today was graduating some of our most promising cadets into operatives, she said with a commanding yet compassionate voice. This actually got the operative's spirits up, with some of them cheering on. Then six child cadets came up onto the auditorium who ranged from 11 to 12 years old, but their faces were concealed by darkness. These six are the few cadets who worked in and succeeded in the S.S.T.P's, She said.

"I heard that some kids come out with broken bones and spitting… blood", another kid said in fear. "really, I saw someone running out of the training hall with bruises and crying for his mommy and that kid was a preteen, another kid said.

Good, come up, 362 says to the cadet as he comes up to the C.O.D.E-M.O.D.U.L.E., but the cadet was kinda uneasy when taking out a booger and putting it into the device. Then a mechanical voice speaks out from the device, "speak operative number for register". Number 7, The cadet calmly says to the machine. "rectified number 7, welcome to the KND", the machine said.

Then some cheering starts to be heard from the stands and 362 comes up to the cadet turned operative. So, what sector do you want to go to number 7, she said to him.

I had my eye on one sector since I came here and its sector v, He said with a grin.
