[ Plum ] Monochrome but Yuri and Sayori Sings it

For context at around 2:03: It is now act 4, Sayori is now the president, which means she became conscient just like Monika is the First and Second act, she is trying to do the exact same thing like Monika did. Yuri like Natsuki, she realizes what is going on, but it is too late, Sayori already corrupted her chr file, she puts Markov Notes to try and make Sayori lose, but it fails and she dies.
