Mikoto is reminded of rumors about there being a clone of her and attempts to question the girl, who was distributing the envelopes in order to fill the alleyways that security cameras can't reach with human eyes. However, the girl leaves after inadvertently setting the building on fire whilst burning the evidence, simply stating Mikoto is better off not knowing as she would be unable to stop what was happening with her power. After saving the SkillOuts, Mikoto looks up for information on the girl, whose name is revealed to be Shinobu Nunotaba, learning that she worked at the same medical facility where she had given the scientists her DNA map years ago. Mikoto infiltrates the facility and comes across a room that is separate from the rest of the building's network. Mikoto hacks into database there and is shocked to learn that the scientists tricked her into giving them her DNA map in order to create clones, known as "Sisters", for a project known as Radio Noise. However, the project was canceled when the super computer, Tree Diagram, deduced the clones wouldn't come close to matching Mikoto's level of power. Believing there weren't any clones of her after all, Mikoto feels relieved and leaves the facility, unaware of a clone arriving later to delete the database.
