A/N
The pun in the title will make more sense later... 

A tall teenager let out a blood curdling scream as a younger teen stood over the mangled mass of flesh and bone laughing. The yellow hoodie of the writhing girl had long since been stained a deep red, and she was no longer human. At least not visually.

The brunette who was laughing looked down on the mutilated girl at her feet and sneered, "Honestly, did you think you could really save Pine Tree that easily, Tonie!" Tonie looked up, surprise and pain spread across her face.

A demonic and pained gasp escaped the dead-but-dying girl's lips, "Y-you calle-alled me b-b-by my nam-ame!" The Dream Demon hybrid used her powers to try to see into the opposing Demon's mind, but not before the possessed girl took out a knife and kneeled down, holding it against her throat.

Eerily the demon chuckled, "Goodbye Music Note, I'm sorry for my error!" and dragged the silver blade across Tonie's neck, ending her suffering.

For now...
