Witness-chan sports long scarlet hair that she wears in twin tails and scarlet eyes. Her hairstyle is the same as Saki Miyu's first hairstyle, and her bust size is 1. Before her initial removal from the game, she wore the default female school uniform. As of her re-implementation in the October 17th, 2019 Build, she can be seen wearing a maid outfit.
Witness-chan first appeared in the "How to Get Away with Murder in Yandere Simulator" video. In the video, she witnessed Victim-chan being murdered by Ayano Aishi. She then ran out of the school and called the police. She was later murdered by Ayano and left on school grounds along with other evidence. This ultimately caused Ayano to be arrested by the police due committing murder without disposing of the evidence.
She briefly appeared later in the January Osana Progress Report - Part 1 and Making Senpai Reject A Love Confession In Yandere Simulator videos, where she witnessed Ayano poisoning Osana Najimi's bento.
Witness-chan had a different routine from all the other students, being placed at the front of the school so she would be able to see Victim-chan's death. Her routine included standing in a corner where she could witness Victim-chan being murdered.
- Witness-chan's expression was the first to be traumatic, more specifically her reaction to seeing murder.
- Although she was removed before strength was introduced, it can be guessed that she was incapable of self-defense because Ayano was able to easily kill her in the videos in which she appeared.
- For now, even her function in the street is unknown for its permanency, if at all.
- YandereDev will not change Witness-chan's hairstyle unless it looks very similar to the original one.
- Witness-chan was initially removed from the game along with Victim-chan because they only existed for the sake of demonstrating a game feature in one video and because they weren't fully fleshed out characters.
- Her initial existence in the school may be proven by looking at the JSON files from some old builds (from March 1st, 2015 to April 8th, 2015) and in videos posted by Yandere Dev in the past.
