One of the best episode so far, especially the profound exploration of Ishimaru's character as an antagonist and the theme of his hatred being something planted and spread. He creates great symbolization that people can truly see the harm of simply succumbing to hatred. There's also the implicit reasoning reveal of why the people weren't growing older. I also enjoy how deconstructing Sakuna's character is something that is gradually made throughout the episode with different facets of it.
