The older twin of Febri, she looks almost the same as Febri, only difference being she has one ahoge instead of two.
It is later revealed that Janie, who is Febri's older twin, is the first successful artificial human created by a group of scientists, Shinobu Nunotaba being the one who programmed her using Testament, much like she did with the Sisters project.
However her body is unstable and the only way she can survive is by eating the odd flavored lolipops she carries in her purse which destroy the poison released by her altered body cells, without them she will eventually fall into a feverish state and, if left untreated, it will kill her, as she has the same biological base as her younger twin, Febri.
After being rescued, she and Febri are in need of body readjustment at outside institutes and Nunotaba Shinobu became their guardian for their trip.
