Hannyaji is in the Student Council office when Misogi Kumagawa arrives.She watches on as Jakago demonstrates her ability on Sukinasaki. Hannyaji tries to attack Sukinasaki when she uses her Error Message Plate on Jakago, but gets taken over herself. Later, the Student Council surrounds Kumagawa in an empty classroom. Like the other members, Hannyaji is confused when she tries to remember why they attacked Kumagawa. Along with the other members of the Student Council, she is defeated by Kumagawa before she can even use her ability.  After Fude Ezumachi returns to the school and begins changing the colors of almost everything, Hannyaji is shocked by the emerald-green classroom interiors, and compares them to The Wizard of Oz. When Iya Renpei compares the orange tap water to Ehime Prefecture, Hannyaji and the others tell her she is wrong.

What started as a simple assistance program has escalated insanely out of control, and now Medaka Kurokami finds herself exposed as something far more than human. But that's only the beginning of a new series of shocking revelations that lead towards a dark secret plan that not even the unbelievable power of her War God Mode may be able to withstand. Still, Medaka's proving to be good at thinking outside of the box, and if she needs the full backing of every hidden resource of the Student Council to meet the challenge, then that's what she's going to get. Even the Abnormal ones!
