Death Reaver Boranoi II is a Yamatian tree hamster owned by the notorious pirate captain Yousei Kaizoku who named him after his late pet, Death Reaver Boranoi I. The notorious farts and explosive diarrhea of Boranoi II are a secret weapon Kaizoku uses sparingly due to the horrific side effects which can be smelled for days despite heavy scrubbing. Kaizoku used Boranoi II's secret weapon when the Black Hunters were being chased by demons in the aftermath of the Battle of Otoineppu.
