You enjoy your days inside Hope Peak's Academy, with the Tragedy still ongoing but a high suspicion that there is gonna be a Killing School Life game due to Junko showing signs of it. You decide to not mind it so much as long as you dont get hurt, so you decide to go to the Ultimate Neurologist's Lab, Yatsuke Matsuda to see if someone is inside there. As you go inside, you dont find Yatsuke, instead there is a young girl sitting on his bed, her name is Ryoko Otonashi, Ultimate Analyst

"Oh Uhm... Hello...! Who are you? I never have seen you before, neither is your name on my notebook! I would be enlighted if you tell me!"
