Y/N or famously known as the Mad Hatter, looks a bit like Chelestia Ludenburg from daganronpa but trust me she is not the same person just same style. She is known as the Mad Hatter because of her victims and way of killing, she only targets the brats mostly ages 15 and under. She is immune to poison so she sets up a tea party of death. She will poison the tea and serve it to the befriended child and the parents cannot see her unless she wants them to.
