|Appears||Week 1 (Debug)|
She initially had long, black hair with a red streak to the left of her face and red eyes that matched the streak in her hair. Her appearance was changed because her previous style looked too close to someone else's art and they requested for it to be changed.
As of the March 15th, 2016 Build, she had dirty blonde hair and purple eyes. She wpre a surgical mask that has a black X over a grey background. She used a steel pipe as a weapon.
In the January 1st, 2016 leak, her design was completely different. She had long, black hair similar to Mai Waifu's first hairstyle, without the red streak. She wore a mask with red markings that read "くそ", which is a Japanese profanity. She did not hold a weapon.
Among the personas currently in the game, Red had the delinquents' persona. If the player got too close to her, she would shove them away. If Yandere-chan attacked the delinquent, Red would attack Yandere-chan and put her in a coma. If Yandere-chan had a weapon out, she would assume a menacing stance, ready to fight.
She spawned by the right side of the disposal area at 7:15 AM. She disappeared at 8:30 AM and returns at 1:15 PM. She disappeared again at 1:30 PM, this time for the rest of the day.
- She was implemented in the March 2nd, 2016 Build.
- She was removed in the April 26th, 2018 Build.
- Red kept her identity hidden so that it was harder to link her to her crimes.
