Confusing for a Tsundere Girl

The execution starts off with Osana looking around seeing the other characters until a shackle grabs her by the neck and dragging her away. As the scene cuts to Osana finally arriving at the room she gets dragged in, the shackle unbuckles allowing her to run....however, she could see shadows of her stalker, her best friend Raibaru and they're just watching her as she runs....she seemed like she was able to escape but it was only an illusion created....she could see Taro and she desperately runs towards him wanting his help....however, she noticed shadows of Ayano laughing at her and "Taro" looking disappointed in her....he crosses his arms and shakes his head avoiding eye contact with distracted her from noticing the knife in her hand....almost as if she was under control by Monokuma, she holds the knife out and stabs herself in the neck before pulling it out making blood pour out....revealing that her eyes are now pure gray indicating she was mind broken after Taro's rejection....she falls to the floor lifeless....the scene zooms out seeing Monokuma in Ayano's wig and the school uniform watching menacingly at the scene before it fades to black.
