LUPIN THE IIIRD: GOEMON'S BLOOD SPRAY

A yakuza boss hires Goemon Ishikawa, a modern day samurai, to protect him aboard his cruise ship casino. Everything goes sideways however when a terrifyingly powerful man— the so called “Ghost of Bermuda”— shows up to put world-famous thief Lupin in the ground... right when Lupin’s trying to rob the very same ship! With his employer dead in the ensuing chaos, Goemon’s honor is at stake, and the only way to preserve it is with blood. But this opponent is like no other, and to make things right, Goemon may need to sharpen not only his sword, but himself as well! With a little help from Lupin and Jigen, of course.
