Nao Hirose appears in the narrative alongside Juu Juuzawa. In a calculated evening encounter, she manipulated Juu's hand onto her buttocks, framing him for sexual harassment.

Subsequent revelations showed Nao's primary goal was not Juu's arrest, but accruing specific "points" by creating difficulties for him.
