Visual Novel Edit

Vega and Altair/Gehenna's Stigma Route Edit

During the Future Gadget Laboratory's Christmas Party, she and Rintaro Okabe both collapse as the world line changes to one where World War III has begun earlier than Suzuha Amane foretold and the Soviet Union still exists. A man by the name Shimoyama interrogates both her and Rintaro, tricking both of them into revealing that they know of an alternate world line where the USSR hadn't fallen.

After the worldline changes mysteriously once again, Rintaro discovers that Katsumi is still hospitalized after collapsing from Reading Steiner's effect on her body, so he, Mayuri, and her friends go to visit her. While there, Rintaro confides in Katsumi the secrets of Reading Steiner and worldlines, which Professor Alexis Leskinen later learns from her. It's heavily implied that Professor Leskinen brainwashed Katsumi to obtain this information.
