Kazer slashed away at the Heartless, his Nineblade with all blades out. He leveled a platoon of Soldiers, and then saw another Heartless emerge from the ground. He had never seen this kind of Heartless, and figured that he should test its abilities. He sent a Water Clone towards the Heartless, but the Heartless brushed it aside, dispersing it. Before Kazer could react, the Heartless grabbed him on the shoulder, and he felt an immense pain begin to ripple through him. "What are you--" he choked, but couldn't finish the sentence. He yanked away and took a defensive stance, then noticed his hands. He gasped in terror.
"You still haven't removed it....have you?" a dark voice said in his mind. With no other explanation, he assumed that the Heartless was using telepathy. However, that meant that the Heartless had higher mind functions, and was not normal.
"Explain this!" Kazer demanded.
"I've been watching you for a time....under HIS orders. He admires your growth, and says that your strength is near enough to its peak for this choice. He wishes you to join him. Agree, and great power and recognition is assured. Refuse, and you will be relentlessly attacked; we will force your alleigance, and we needn't worry about killing you in the process."
Kazer slashed, but the Heartless dodged with incredible speed. "You know my choice. I'll never join him!"
The Heartless smiled. "Then you put your friends in danger?"
"They can hold their own in battle. And if by a slim chance you overpower them, I will protect them."
The Heartless laughed, a terrible sound like claws screeching on a blackboard and banging on pots and pans. It then disappeared, leaving the normal Heartless to occupy Kazer. He took advantage to errect a barrier and use a sealing Jutsu to reverse the effects the Heartless had caused, then proceeded with slaying the remaining creatures of darkness.
