In this volume, Ogami Ittō steals a secret Yagyu letter, effectively throwing down the gauntlet, and Yagyu assassins ramp up their attacks in response. There are few standalone chapters as the main plot takes the driver's seat.
In a flashback, we learn that Yagyu Retsudo had been planning his treachery against Ogami Ittō for years, beginning before Ogami was even granted the post of executioner.
In one story, a friendly doctor asks Ogami all the burning questions that the reader has been thinking for 1500+ pages. How can you justify endangering a child this way? Don't you love your son? Don't you want him to be safe? Even if this violent path is necessary for you, what the hell is wrong with you dragging a toddler into it?? Can honor truly demand this??
Kazuo Koike's illustration continues to astound me. A two page spread of a cabin in the woods in the rain (p500-501) could be framed and hung on the wall; it's so rich I forgot it was black-and-white. And Daigoro's little face and body expressions...when a village soothsayer freaks out at his eyes, at what they indicate he's seen, at his unnatural composure--the reader can see exactly what she means. It's there on every page, both his innocence and his tragic maturity of spirit. It's uncanny.
