It's fake.
Naoko had friends before SM. Most of them also privileged people.
She’s always mingled with Japan’s upper crust. All that narrative about Naoko working so hard to get her chemistry degree, her job as a pharmacist, her gruelling and exhausting work at Nakayoshi, the victimhood built around her during the creation of SM and the later cancellation of PQ Angels, her hard work as a mother, and so on... it all falls apart if you dig a little deeper. Just read her comments in the tankoubon of her stories, and you’ll see it doesn’t hold water.
Her university? Private. Her pharmacist job? Given. Meeting with Togashi? Planned by their rich mangaka friends they had in common. Sailor Moon? Orchestrated and developed by big companies, she was only part of the gear assembly.
Her stint at Kodansha is the only genuinely modest job she’s ever had in her life and she complained. So, yes...... she's a Hime-sama in real life.
