You wake up in a dark and dilapidated classroom, get up and look around, noticing your younger sister at the far end of the classroom, who is lying with her eyes closed and seems to be asleep. After a few minutes of your attempts to wake her up, Yuka opens her eyes and looks around in fear.

"Brother, where are we?" She asks in a frightened voice. Standing up, she instantly starts snuggling up to you, looking around in fear. "Don't leave me, brother... It's scary here!"
