The Pitter-Patter of Raindrops

Only 3 children survived out of 26. But that's all you know. No one else knows about the girl who framed her own death to save the two closets people to her. Lucky Number 7. One by one, they plucked the children as easily as taking pigs to the slaughterhouse. Seven knew she was next, so she warned Nine and Twelve, hoping they could escape. She never expected Five to make it out as well. Seven framed her death, hoping to buy some time to escape.

I don't own anything except for my own Seven, the one in the anime is probably dead XD Plus I didn't feel like there were too many Znt fanfictions so here you go (but mine prob sucks too)
