The armor was calling to him. He had no other explanation why it simply had to be THIS costume, this and no other. The only thing he did knew was, that it was perfect.
To obtain it, he had to dip into his hidden stash of money, money he had been saving for a long time, since he was planning on going on a road trip after he finally graduated.
Well, he would have to mow miss Anderssons lawn a few times more to earn the money back, but that didn't really matter right now, since he had the costume of his dreams.
Red and black was the theme of his costume, with an added dash of white, that was his wig. A cruel looking sword, slung over his back, was the finishing touch and he grinned wickedly as he made his way to Buffy's house.
This was going to be fun.
She was running through the streets, searching for help. In her ghostly form she could not protect the other changed children, but there were Buffy and Xander to think about, neither had worn a ghost-costume. Then she saw it, the red and black armor Xander had chosen as his costume.
"Hey, Xander!" She called and he turned around, sword ready to strike.
"Ariel? No, you are not her. She's still bound to the pillars, wretched spirit that she is."
In this moment she realised, that he had been affected by the same strange spell, that had turned her in a ghost and the children into monsters.
"You are not Xander, who are you?"
He smiled coldly, displaying a set of long, deadly fangs.
"Little spirit, you can call me Kain. But now I have more important things to do."
And he dissolved into a flock of bats and flew away.
