It seems there might be a misunderstanding or a typo in the request. The provided context for "A Silent Voice" extensively details the plot and characters like Shōya Ishida, Shōko Nishimiya, Yuzuru, Tomohiro, Miyoko, Naoka, and Miki. However, there is no character named "Sanji" mentioned in the summary of "A Silent Voice" that you provided.
Therefore, I cannot explain "Sanji's role" in "A Silent Voice" based on the authoritative references given.
Could you please clarify?
- Did you intend to ask about a different character from "A Silent Voice," such as Shōya Ishida or Shōko Nishimiya, and "Sanji" was a mistake in the title and keyword?
- Is there an additional context or a specific interpretation of "Sanji" within "A Silent Voice" that I am missing?
If you'd like me to craft a Super Pillar hub article about a main character like Shōya Ishida or Shōko Nishimiya using the provided context, please let me know, and I can adjust the title and focus accordingly.
