A remaster that blends aspects of the original game with Sigma 2, titled Ninja Gaiden 2 Black, was announced and released for PlayStation 5, Windows and Xbox Series X/S on January 23, 2025.

9 days later, on September 20, 2007, Ninja Gaiden II was officially unveiled to the public, with its first trailer at the Tokyo Game Show 2007, alongside various interviews.

Ninja Gaiden II's new combat system allows the player character Ryu to dismember his enemies, severing their limbs and tearing their bodies apart covering his weapon and everything around with blood.

Essence has an important role towards general game play, acting to heal Ryu, restore his ki, or increase his cash.

A CIA agent named Sonia enters the place and asks for Ryu's whereabouts, until members of the Black Spider Ninja Clan attack the shop and kidnap her.

Ryu returns to his home and finds his father, Joe Hayabusa dueling with Genshin, leader of the Black Spider Ninja Clan.

Ryu tracks Elizébet down to South America, where she offers the Demon Statue to Infernal High Priest Dagra Dai, in order to resurrect the ancient Archfiend, Vazdah.

An overlooking Genshin explains that the fiends are looking to resurrect the Archfiend who is supposed to emerge from Mount Fuji back in Japan.

As Mount Fuji erupts, Genshin reveals to Ryu that he never cared for "tantrums of the archfiend" and that their moment has finally arrived.

Ryu fights past hordes of Fiends and singlehandedly defeats Zedonius, Volf, and Alexei, and rescues a captured Sonia.

Ryu heads into another room and finds a resurrected Genshin, transformed into a Fiend, back for a fourth and final battle.

Ryu attacks Elizébet, and angrily cuts her down to red dust with the combination of his own dragon sword and Genshin's blade of the archfiend.

Ryu takes down the monstrosity and heads to the surface with Sonia, but a drop of his blood from an open wound accidentally spills onto the fiend and revitalizes Vazdah, who ascends to the summit in its true form.

Amidst an erupting Mount Fuji, Ryu squares off with the Archfiend in a climatic duel to decide humanity's fate and wins.

Initial screenshots of Ninja Gaiden II leaked on the Japanese official Xbox 360 website but were removed within a matter of hours on September 11, 2007.
