One Piece (Volume 08) TPB

If Luffy wants to get out of a year抯 worth of chore-boy duty on the oceangoing restaurant Baratie, he抯 got to rid the seas of the evil Don Krieg. Unfortunately, Krieg抯 armed to the teeth and aided by his Demon Man Commander Gin. The battle takes a surprising turn as Krieg reveals his increasingly deadly military might!
Meanwhile, Nami has sailed off on the Merry Go with treasure in tow, and she抯 headed to Arlong Park, home of creepy Captain Arlong and his Fish-Man Pirates. What business does Nami have at Arlong Park, anyway? Something fishy is going on and Luffy抯 crew just may be in over their heads.
