Well, high school is over for "Daniel-san" and his life couldn't get any worse: his girlfriend Ali has just dumped him for a college football player, and his mother has announced that her company is moving her to Fresno, where Daniel will have to spend his summer. To top it all off, Miyagi must travel to Japan to see his dying father. Not wanting to spend the summer without his sensei, Daniel accompanies Miyagi to Okinawa. Miyagi returns to find that his first love Yukie has never married, while Daniel is immediately smitten with her niece Kumiko. However, Miyagi's old friend-turned-enemy Sato is still bent on revenge against Miyagi in order to retrieve his lost honor, while Sato's nephew Chozen harasses Daniel. Daniel also learns the secret to the Miyagi family's fighting style: the Drum technique. Though Miyagi eventually reconciles with Sato, in the end Daniel must fight Chozen in order to protect Kumiko's and his own life.
