project arrhythmia is a game created by vitamin games and the original storyline is written by lily craver however this is a au and a crossover made by sorayume herself (which is me) and the way she wrote this is trying to write other stories in it (but it's mainly black heart and the actual story line) although I will give you some warnings there will be gore and have really dark topics but other words... please enjoy or cry your tears out if you want Also art by me, sorayume
