(Continued from before)
* Art of Vacuum Wave: This is a variation of the Wind Blades Ninpo, which instead sends vacuum blades simultaneously in an upwards and downwards direction, even though solid objects to strike out of reach enemies. It is used by Ryu in Ninja Gaiden III: The Ancient Ship of Doom.
* Art of the Inazuma: Amplifying the bio electric currents in his body, Ryu is able to quickly charge up electricity in his body, which is then instantly blasted outwards as lightning striking all enemies in the vicinity. Outside of battle this is used to destroy boulders of large rocks. Ryu gains the ninpo scroll for this ability after defeating the electric worm boss.
* Art of Divine Life: By concentrating and focusing his mind, Ryu is able to turn ki energy into blue essences, fully restoring his spiritual health. This is the other of the two ninpo arts exclusive to Ninja Gaiden: Dragon Sword due to the lack of healing items in the game.
* Art of the Piercing Void: The most destructive ninpo in Ryu's arsenal. Ryu first focuses his telekinetic energy created by centripetal vibrations in his lower dantian or ki focal point, then forms the energy using gravitational waves propagated from his conscious spirit, resulting in a rotating black hole trapped inside a semi permeable spiritual force field that keeps it stable. Because of the semi permeable nature of the force field around the black hole, time space fluctuations occur around the black hole as Ryu sends it flying off, it's gravitational pull is great enough to rip the environment around it apart and pull debris encircling into the black hole as it speeds away. Enemies caught in it's path are instantly destroyed, even piercing through multiple enemies before dissipating. Most boss enemies can survive the black hole, but suffer massive damage leaving them vulnerable to a finishing blow.
