It's like the Hitomi hairstyle itself is cursed. Not only did she correctly arrive at the conclusion that Megumi is being possessed, through astute observation and careful interviewing of her students, proving she is actually highly competent, she is surrounded by thoroughly incompetent adult professionals who unilaterally push their work onto her, and the one thing those afflicted with the Hitomi curse cannot do is say "No".
At this rate her rise to the top is as inevitable as it is unwanted. That report she pulled out of her ass? It's going to shape education policy for the entire country for the next ten years, and she'll end up with a much more prestigious post at a top level private middle school, just in time for Megumi/J/Mary to test into it and continue to make her life difficult.
Better make that appointment and get a blond afro. There's still time to save yourself!
