The final page in this chapter. The swordsman has a purpose, a direction, and the motivation to follow through. For the first time in over 2 years, he's ready to end it. He's bringing the fight to the people who need it.
This chapter saw the death of a major character. The final chapter will see the death of at least two more.
From the Hagakure:
"Concerning martial valor, merit lies more in dying for one's master than in striking down the enemy. This can be understood from the devotion of Sato Tsugunobu."
