In Episode 9 begins with a discussion about "Shadow Bushido," an anime that glorifies antisocial behavior. A group of concerned citizens wants to take action against the series because it has a negative influence on children. Oyamada Nasu, the creator of the anime, is introduced as he visits Dr. Sudo's clinic to treat anemia. Oyamada does not apologize for his work and explains that he is merely expressing his own opinion.

Oyamada faces public backlash, including a petition against his anime. Despite this, he remains defiant, even when confronted by protesters.

The episode then shifts to a subplot about a humanoid teacher struggling in a heavily regulated educational environment. The school where he works is so strict that any genuine interaction between teachers and students is suppressed. The teacher eventually leaves his position and transfers to a more open, independent school where he believes he can truly make a difference.

Oyamada, who still plays a central role, continues to defend his work. He argues that society is becoming too restrictive, to the point where being human could be seen as evil. His perspective is contrasted with the experiences of the humanoid teacher, who finds a more fulfilling role in a less restrictive environment.

The episode ends without resolving the controversy surrounding "Shadow Bushido," but it presents various perspectives on ethics, freedom of expression, and the role of AI and humans in shaping societal norms.
