Blade of the Immortal, Volume 4: On Silent Wings

Rin and Kagehisa finally meet face to face for the first time in this volume, and it makes for one hell of an encounter. I'd kind of compare it to the diner scene between De Niro and Pacino in Heat, to a certain degree - in terms of tension, and in terms of how the two characters really end up talking about why they do what they do, and how that makes them similar and different.
