Metal-tan is a robotic like girl with White skin, matching dress, and long black messy hair. She also appears to have robot legs, much like Sabitsuki's Machine Effect. She also appears to have black crosses around her eyes.
- Just like other NPCs you can kill her with the iron pipe; however, unlike other NPCs once you kill her she stays dead even when you wake up. You can hit her repeatedly but she'll stay dead the rest of your game.
- After hitting her once, if you hit her again, she makes a different, quieter painful moan. After that, she makes no other noises.
- Her name was created by fans on Uboachan.
- She has some resemblance to Monoko from Yume Nikki and Visi from Fleshchild
- If you come to her room during the endgame, she is nowhere to be found.
