Vagabond Volume (1 to 11) by Takehiko Inoue (Manga) (English) (Paperback).

Shinmen Takezo is destined to become the legendary sword-saint, Miyamoto Musashi–perhaps the most renowned samurai of all time.

This is the journey of a wild young brute who strives to reach enlightenment by way of the sword–fighting on the edge of death.
