One Piece, Vol. 17 continues where the previous tankōbon left off and contains the next ten chapters (146–155) of the on-going manga series.
This tankōbon concludes the Drum Island Arc. Monkey D. Luffy, Sanji and Tony Tony Chopper fight Wapol and his henchmen, Chess and Kuromārimo. Wapol uses his devil-fruit power to become a cannon-armed house and fuses his men into the two-headed, four-armed Chessmarimo. Sanji's back aches, keeping him from fighting. Chopper takes a drug he calls Rumble Ball, and defeats Chessmarimo.
Wapol sneaks into the castle and chases Nami. Luffy catches up to them as Wapol attempts to open the weapon storage. Unable to do so because Nami has taken his key, Wapol retreats to his cannon at the top of the castle, but the cannon does not work, and Luffy sends him flying off the island. Luffy tries to persuade Chopper to join the crew, and the reindeer finally agrees. With a doctor aboard, the crew continues its journey to Alabasta.
This tankōbon is written and illustrated by Eiichirō Oda. For the most part, it is written and illustrated rather well. The narrative concludes the multi-tankōbon long arc based on Drum Island. Key plot-points are that Tony Tony Chopper is introduced and joins the Straw Hat Pirates as the medic and Zoan type Devil Fruits are introduced which allows the user to transform into an animal species at will or an inter-species hybrid.
All in all, One Piece, Vol. 17 is a wonderful continuation to a series that seems really intriguing and I can't wait to read more.
