The reading experience
Why it stands out.
The Matsuda family lives in a community celebrated as the defensive sword of an empire. Mamoru trusts what he has been taught, while Misaki has deliberately buried a wider experience of the world.
The book’s central battle is severe, but its lasting focus is what war exposes inside a family and culture. High character focus and high darkness are therefore independent of its military label.
