Pippi and Ryuto can be easily murdered here, because they are currently the only two people who will enter this room. Pippi uses the farthest computer from the doors on the left, while Ryuto sits five computers away. Unless School Atmosphere is very low, both will be too distracted by Osu! to notice the murder of another student.
- A removed Easter Egg was the music that played from the computer when the player moved close to Pippi. It was originally the opening theme of the anime Puella Magi Madoka Magica, titled "Connect" by ClariS. In the August 12th, 2015 Build, the music was updated to an original song created for the room.
- The song that currently plays from the computer, when close to Pippi or Ryuto, is a techno/electronic remix of the soundtrack that the player can hear throughout the game.
- Pippi and Ryuto are playing a real life rhythm game called Osu!.
- At one point, during a debug build, YandereDev was testing with transparent windows. He later had to remove them because it dropped the frame rate tremendously.
