Based on the anime Black Rock Shooter, but I changed a lot of things You don't have to watch anime to understand this.
Chapter 1, Part 1: Abandonment
The sound of Sakki's heels echoed throughout what look like a trashed dancehall. The red curtins riped, windows black with dust, very little light came through. She approached a man dressed in all black and blue sitting on a beam high up. She reached out her pale hands as if asking to hold his hands.
The man, she once knew as Blue, smiled darkly as he stood, summoning a ninjato* made of ice, snd jumped down. He raised the blade as he fell, aiming of Sakki's neck...

"Alright, class. Settle down." Teach said. "I want you all to find a partner for this activity"
Everyone in the class got up and sat next to a friend in the class. Sakki frowned, she was fairly new to the school so no one really knew her. "Blue. Work with Sakki today." Teach said.
"Why do I get stuck with the new girl?" Blue groaned. Sakki's face turned scarlet.
"Because Seal hasn't been here for about a week." Teach explained. "Just until she gets back."
"But she looks like those dumb blond girls you see on TV!" Blue said, now angry. Sakki got up and bolted out the door.
Her feet pounded against the tile, she started crying. Voices that were not hers echoed in her her head.
"I feel alone...where are they going? Why are they leaving me here?" The voice in her head rang. Was this her going crazy with rage? "How could this happen? Why am I alone?"
"Save me," the voice said. Then, for Sakki, total darkness.
