For context since this is recent, Nina Watari (the girl calling Suwako gay) absorbed a bunch of AI misinformation that the Lunarian filtered out, and since she had no way to tell whether they were true or not, she became a massive conspiracy theorist, believing that misinformation to be true.
Her Spell Cards even references those weird theories and how she sees them as truth, such as flat earth, chemtrails, lizard peoples, and of course, a certain conspiracy that came from a nonsensical answer the japanese version of Siri would give about a land called Zoltax and it having rivers of chocolate.
