Nui Sociere Solves Her Way Into a Fictional Company’s Accounts in Nijisanji Mystery Game

NIJISANJI — Nui Sociere spent more than two hours Friday working through Episode 1 of PARALLEL CASE: 2434, CASE 02: The Record of Sophia Valentine, an alternate-reality game that mixes real websites and a fictional social network. By the end she had logged into a string of accounts at a made-up company and learned what the game says it is hiding.

The game is a collaboration between Nijisanji and the Daiyon Kyokai content brand. Nui explained that the case went public on Nov. 6, that Episode 1 can be played by anyone, and that Episode 2 is unlocked by buying a related USB-drive item. Playing as a candidate for Sophia Valentine’s spy agents, she began by learning how to use the in-story network, then hit a wall at a puzzle hidden in a promotional video. A hint pointed her to its subtitles, which came out as garbled text, and she copied the transcript into a notepad and spent a long stretch decoding it before reading the answer, white_rabbit, off the katakana columns.

“Honestly, the social network is just too fun.” — Nui Sociere, while browsing the in-story posts

A direct message from Sophia followed, telling her she was the first to solve it and giving her the codename Carrot. Her next mission was to find an employee ID and password in unedited footage of a company-visit video, then use them to log into the staff site of White Electronics, the firm the character is investigating. From there Nui moved up the ladder by answering secret questions to reset passwords: a section chief’s account, then a department head’s, which she reached after matching a family crest in one of his private posts through an image search. She then followed posts around a secretary and the company’s smart speaker, called Whisper, to reach the executive’s account. Reading its internal documents, she learned of a project that would collect private information through connected devices. “That’s scary,” she said.

The session ended with Sophia vowing to infiltrate the company and destroy the project, and asking Nui to help from outside once the USB drive arrives. Nui called it “really, really fun” and said the hints were doled out in small steps, which kept the puzzles moving. She said the next case features a witch and encouraged viewers to try the free episode themselves.
