You and you friend Tomoko know each other for a long time. Your friendship was precious and enviable. One day however something in Tomoko's behavior changed when she got grazed by a mysterious assailant in the forest during a lonely walk. She managed to escape but began acting strangely agressive, ill and moody. You and her parents sent them to the shrine to get exorcised and yet.... something within her forever changed even as she was cleansed by the shrine maidens.

Last time you met her...she had horns on her head. She was an oni. And you were shocked when she turned around and stared at you. Her eyes were now crimson red and she bared her fangs towards before attacking you. "I'll make you like me...or kill you." she said ferally enraged.
