Sitting in class listening to an old man recite tales of past glories was very near the bottom of the list of things Kai enjoyed doing, even on a good day. But it being his final class on a Friday evening Kai was bored out of his skin. So when the bell signalling the end of class rang he was out of the room before anyone else but he didn't get very far, this was in part due to him being mowed down by a blonde boy who was sprinting down the hallway, he was obviously late for something Kai didn't get the chance to ask because before he was able to comprehend what was going on the boy had turned the corner at the end of the hallway and was gone. "Well that was weird." said Fletcher as he reached down to help Kai up.

"Tell me about it, where do you think he's going?"

"To be honest mate I really couldn't care less." replied Fletcher bluntly "But it looks like he's heading in the direction of the training hall."

Kai looked around him the rest of his team had joined Fletcher and him outside; Iris and Ashley the two female members of team AIKF were looking concerned as Fletcher pulled him off the ground.

"I'm fine." Kai reassured them.

"Really?" questioned Ashley the leader of the team.

"Yeah of course why?"

"Well for starters your shoulder is doing that weird thing again." Iris added helpfully.

Kai looked down at his left shoulder and sure enough there was his arm, dangling out of its socket.

"Not again." Kai moaned as he moved to push the limb back into the joint.

"Don't do that!" Ashley snapped loudly. She grabbed is good arm and began to drag him down the corridor towards the infirmary. Fletcher and Iris began to follow but Ashley told them that she could handle taking Kai to the infirmary and that they should enjoy their Friday evening. As she said this Kai noticed her wink at Iris who then insisted that Fletcher should come with her to the cafeteria to get some food.

After the rest of the team were out of sight Kai begin to resist against his team leader which didn't take much effort as he was a lot bigger than the black haired huntress. Ashley finally gave up and turned to face him.

"Kai, tell me what is going on with that shoulder of yours."

"It's nothing; really it's not a problem."

"It is a problem! It is a huge problem!" the huntress was getting agitated. "What if your shoulder does it again but during a fight or… or in a much more serious situation?"

"It won't be an issue." Kai insisted.

"Yes it will! I have a responsibility to make sure the team is on top fighting form and you have a responsibility to ensure you are combat ready at a moment's notice."

"Fine, what do you want me to?"

"I just want you to get someone with a medical degree to look at it and if they say its fine I'll get off your back."

"I can't do that." Kai could barely look her in the eye.

"Why?" The huntress once again looked annoyed as she thought she had made some progress.

"I really don't want to talk about it."

"Kai, please the team needs to know what's wrong. "

It was at this point that Pyrrha Nikos entered the hallway and saw the black haired huntress arguing with the tall blonde huntsman. She considered walking back the way she had come to avoid going near the pair, until she realised she knew the huntsman. So without thinking she began walking towards the pair and called his name.

Kai looked up in response to his name and when he saw the red headed Spartan walking towards him all he could think was "Great she's going to make this worse…"

Pyrrha really couldn't understand why her old friend wasn't excited to see her, as she approached the pair she saw Kai's shoulder and remembered the day that the incident occurred.

Two years previously Pyrrha had been standing opposite Kai dressed in his full ninja uniform in the final of the Gauntlet tournament, they were both very tired as they had been fighting for nearly half an hour neither of them giving any quarter. To say they were rivals would be an understatement, Pyrrha knew the Ninja well. They had been training partners, until she had started fighting in tournaments at which point they had gone their separate ways to ensure the other was unable to learn how the other fought. They just about maintained their long standing friendship but that was always hard when you were nearly always trying to hurt eachother.

It was at this point that Kai charged at her, Pyrrha changed her spear into its rifle form and took aim but just as she was about to fire the Ninja threw a small black sphere at the ground. The sphere shattered releasing a plume of black dust that enveloped the ninja. As the dust quickly cleared the Ninja was nowhere to be seen, "Well that's new," she muttered to herself. She stood there looking around wary of an attack; little did she know Kai was standing on the lighting rig at the top of the arena.

The Ninja was content that she had no clue where he was so he took his time in planning his next attack. He slowly removed three shuriken from a concealed pocket in his jacket; he began to run along the lighting rig throwing the shuriken at spaced intervals so the Spartan would not be able to determine his location. As the throwing stars hurtled towards the Spartan she turned and placed her shield between her and the sharp throwing stars.

There were three consecutive thuds as the shuriken lodged themselves into her shield, Pyrrha was pleased with herself she had sensed the attack with her Aura what she didn't realise was that the throwing stars were a distraction and that the Ninja was directly behind her. The only thing that alerted her to the presence of the Ninja was the chorus of her supporters screaming that she needed to turn around.

Kai smiled behind his hood as he drew his two swords and jumped from the rafters towards the huntress. As he descended the Spartan began to turn and she raised her spear…
