Teenage ninja girl Yumei has gotten used to surviving havoc in Hawaii. On a daily basis she has to cope with a blind ninga samurai, an overly talkative bully, an overbearing, buxom wrestler and the daughter of a Norse god. Ex-bully Michael finally works up the nerve to ask Yumei to the prom, but on the porch of her house, he sees ninja-samurai Yoji being stabbed with a poisoned knife! The assailant demands that Yumei come face her in Kyoto within two days, or Yoji dies! It all comes to a thunderous conclusion for the entire cast in the final volume of NHS: Hawaii!
