Ninjutsu, also known as Ninja and Ninja Magic in other translations, is Edge's special magic in the game. It combines aspects of White and Black Magic, but focuses primarily on Black Magic. The Ninjutsu command's Charge Time varies, and its charge time it taken from the spell the player selects to cast.
In the Nintendo DS version Edge learns three new Ninjutsu: Tremor, an Earth-elemental attack, Frost, an Ice-elemental attack, and Gale, a Wind-elemental attack. Edge learns new Ninjutsu techniques as he levels up, with the exception of Flood and Blitz, which he learns after going into a rage at Rubicante after his parents had died at the hands of Dr. Lugae.

Ninjutsu comes in three different forms, enfeebling, enhancing, and offensive, although unlike White and Black magic, the form of Ninjutsu has no significance: they all are based on a single magic skill called Ninjutsu skill. The most commonly used Ninjutsu are Utsusemi: Ichi and Utsusemi: Ni, which allow a ninja to absorb a number of attacks equal to the number of copy images. Utsusemi forms the basis of a ninja tank.
While not appearing as an actual skillset, two Ninjutsu abilities, Flame and Flood, appear as locked abilities for the Purple Lightning garb which is available through a side quest in Luxerion. While both abilities share the same animations with Firaga and Blizzaga respectively, they deal physical damage and Flood deals ice-attribute damage instead of water-elemental since the element only appeared in Final Fantasy XIII. Another two Ninjutsu abilities, Lightning and Wind Slash, appear as locked abilities for the Blue Mage garb.
