Hien Hōsen: Mode One (飛燕鳳閃・壱式 - Hien Hōsen • Ichi-Shiki, lit. "Flying Swallow Phoenix Flash • Style One") is one of Ikaruga's Secret Ninja Arts that appears throughout the Senran Kagura series.
Overview[]
Burst[]
(Ikaruga's Secret Ninja Art: Requires one Ninja Art Scroll to use.)

Ikaruga takes a stance as she readies for her attack. She then slashes rapidly with her sword, Hien, moving so quickly that it leaves behind afterimages of where the sword had struck. She then proceeds to sheathe her sword as the last bit of damage from the sword strikes take effect.
Deep Crimson[]

(Ikaruga's Secret Ninja Art: Requires one Ninja Art Scroll to use.)
In Deep Crimson, Ikaruga takes hold of Hien and slashes the air in two, large swings. She then turns her back and proceeds to sheath her sword, leaving behind afterimages of the areas of which she struck. The damage from the sword's strikes soon take effect. Though not very damaging, the aftermath will fling enemies away from the general area.
Shinovi Versus[]

(Ikaruga's Secret Ninja Art: Requires one Ninja Art Scroll to use.)
Ikaruga takes a stance as she readies for her attack. She then slashes rapidly with her sword, Hien, moving so quickly that it leaves behind afterimages of where the sword had struck. She then proceeds to sheathe her sword as the last bit of damage from the sword strikes take effect. This attack is stationary and is usually good for up close encounters with several enemies.
Estival Versus[]

(Ikaruga's Secret Ninja Art: Requires one Ninja Art Scroll to use.)
This attack retains most of its uniform actions from its previous games. However, there is a minor difference in the Art's execution. Ikaruga takes a stance and, in on swing, causes Hien to slash about in a frenzy of precise cuts. The damage takes affect after the sheathing of her sword. This attack now has strong suction that draws in enemies to the center of the attack, before being tossed by a forceful shock-wave.
