Lamplights through windows and profoundly aged wood are adding even deeper tastes to the Japanese style passage in Sky City Tokyo. There, Ryu beheaded a Black Spider Ninja. This is a finishing slash for the enemy Ninja whose fate did not allow prompt death and forced him to crawl against Ryu even after losing legs and deadly bleeding. Ryu Hayabusa cut off his head to release him to death. This is a Ninja's pity on enemy, so called "the Obliteration Technique."
