Seven Secret Swords

Secret Swords (秘剣, Hiken) are seven secret techniques that Ikki Kurogane created.

Description
The Secret Swords are seven sword techniques, which Ikki Kurogane had created in order to make up for his lack of magic and just focused training in swordsmanship and martial arts. He has revealed a number of these secret swords in battles against other Blazers during the Seven Stars Sword Art Festival Selection Matches. At first, a lot of his secret swords relied on using his Ittou Shura and wouldn't have work overwise, however, using Blade Steal to "steal" Edelweiss' Swordsmanship, Ikki became able to utilize his various secret swords without needing to use his limited Noble Art. During the finals of the Seven Stars Sword Art Festival, after reaching his "Awakening", Ikki invented the Final Secret Sword (終の秘剣, Tsui no Hiken) in order to defeat Stella.

It has later been shown that he is able to combine some of the secret swords together into one as shown as Ikki used Rekkou, which was powered with the effects of Donkuga-no-Taichi. He was able to also combine his own original sword technique with other techniques, this is first shown as he used the Amatsukaze from the Kurogane Clan's Kyokujitsu Isshin-ryuu combined with Raikou, which created the technique referred to as Amatsu Raikou.

Seven Secret Swords

 * 1) Saigeki (犀撃, Rhinoceros Strike): A charging technique, where Ikki uses his arm strength, leg strength, and charging power combined with his superhuman body control in order to focus the vectors of his power at the point of his sword, thus granting Ikki the highest offensive power among his secret swords. This is an anti-material sword technique. Although at first Ittou Shura is needed in order to use this technique, Ikki after he learned Edelweiss' sword technique is able to use Saigeki without entering Ittou Shura.
 * 2) Rekkou (裂甲, Rend Armor): A point-black slash, where Ikki uses the bodies' lower torque in order to strike his opponent after blocking their attack.
 * 3) Madoka (円, Circle): Ikki receives an attack, taking the power, then he rotates himself around as if making a circle, then sends it back as a counter. Madoka has shown to be a useful technique against more powerful opponents such as Ouma and Stella. In the finals match of the Seven Stars Sword Art Festival, it has been evolved to where Ikki doesn't even require to spin himself around anymore, he instead uses his broad back muscles to transfer the force into his next attacks. Stella stated that in order for this to happen, his muscles had to be as loose as jelly, even looser than normal, this is dangerous as even a moment of stiffness would result in his muscles to explode from the force being redirected.
 * 4) Shinkirou (蜃気狼, Mirage Wolf): Using radical footwork, Ikki creates an afterimage before himself while running to confuse his opponent, then vanish like a mirage after being struck.
 * 5) Kuruizakura (狂い桜, Off-Season Sakura): A sword attack with a delayed effect using slashes with certain force and mechanisms to create wounds that won't open until later on.
 * 6) Dokuga-no-Tachi (毒蛾ノ太刀, Poisonous Moth's Long Sword): From his feet to his fingers, Ikki has all his muscles work together to create shock waves, then the moment that it comes into contact with their weapon or armor, then transmitted into them causing numbness in their muscles forcing them to drop their weapons and even affecting internal organs.
 * 7) Raikou (雷光, Lightning): The fastest among his secret sword technique, where Ikki perform a sword swing at such speed that it exceeds ones' dynamic vision making it appear as if it were an invisible slash. At first, it required Ittou Shura but after learning Edelweiss' Swordsmanship, Ikki's reflexes and speed are fast enough to able to use this without using Ittou Shura.

Final Secret Sword

 * 1) Oikage (追影, Seeking Shadow): A technique that Ikki developed in order to defeat Stella in the final match of the Seven Stars Sword Art Festival. After breaking the chains of fate binding him, in which he puts all the excess magic gained to activate Ittou Rasetsu and uses a battōjutsu using his hand as a sheath for Intetsu, then unleash a slash so fast that his shadow couldn't keep up with his movements.
