Little Ninjas

War is bad. It is especially bad when conducted by kids. When kids spar against each other with wicked intent, the results can be nasty. I have the dubious honour of presiding over a kid’s class that consists of two students who are hell-bent on the others destruction.
Their names are Yuuki and Amane. I haven't the luxury of a back-story that led to their respective loathing but all I know is that if I wasn't there to supervise them, they would fight to the death.
This afternoon class requires more effort from me than normal lessons. Mainly because I have to plot and pace my lessons in order to avoid a bloodbath.
One tactic I use is a seating plan where I make Yuuki and Amane sit as far away from each other as possible. This has the potential to work, but on continuous occasions Yuuki or Amane will stare with ferocious intensity at each other then leap up on the table to start wrestling. After sweeping from the table the clumps of hair Yuuki and Amane tore from each others head, I will get the kids to spread out in the room and make sure the two little psychos are a healthy distance from each other.
Believing that everything is settled, I might get the kids to play a quick game of Simon Says.
It's quick, easy and fun. But with Yuuki and Amane's participation the game becomes violent, stressful and destructive.
The three other members of the class are great, and will laugh and clap with joy as we play the game. Amane and Yuuki have other plans as to the direction this game will take.
"Simon Says......" I boomed, whilst I thought about the body movement. As I did so a loud cry erupted from both corners of the room. I look down from my thinking pose, and saw Yuuki and Amane charging at each other with flying kicks. I tried to break up their fight but they kicked my hand away and resumed beating the shit out of each other. I took matters into my own hands and stood as an obstruction between them. They didn't notice and continued to kick and punch me.
The other nice kids were looking on with mouths agape in horror.
I pushed Yuuki and Amane apart with my two hands, and held them in this position until they calmed down.
I asked why they disliked each other with a passion.
Yuuki said Amane was an Unko.
"What's that?" I said.
He pointed to his bottom and made farting sounds.
"Right. I see. And Amane, why don't you like Yuuki?"
He held is winkle and starting mock urinating onto Yuuki.
"Stop that!" I said and reprimanded them for being vulgar. I warned them not to fight again otherwise I would tell their parents about their poor behaviour. That seemed to mute them.
It was going well until I ended the lesson with a game of Pictionary. The kids could draw anything they liked and the others had to guess what the English word was.
When it was Yuuki's turn, he strode up to the whiteboard and drew a lumpy object with flies buzzing around it.
"OK kids, what's that," I said, still not sure what Yuuki had just drawn.
"Poo-poo!" the kids yelled.
"No," Yuuki said with a grin, "It's Amane!"
And in a flash, Amane leapt from his chair onto the table, lunged towards Yuuki and started thumping him.
