One Piece, Vol. 16: Carrying on His Will

Avalanche! Luffy and Sanji surf a tree down a mountain on a fast-moving wave of snow and just avoid being buried alive. But then the demented King Wapol suddenly appears and orders Luffy's and Sanji's deaths. With no time to lose, Luffy evades the attacks. Then, out of the blue, an unlikely friend comes to his rescue! A friend who was trying to kill him only hours before! -- VIZ Media
