Seven Secret Swords

The Secret Swords are seven techniques that Ikki Kurogane had 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: His First Sword, a charging and anti-material, where Ikki uses his arm and leg strength alongside his charing power combined with his superhuman body control; focusing all the vectors of his power directed at the point of his sword, granting it the highest offensive power among his secret swords. Ittou Shura was required to use this technique, Ikki after he learned Edelweiss' sword technique is able to use Saigeki without Ittou Shura.
 * 2) Rekkou: Ikki's Second Sword, a point-black slash, where Ikki uses his bodies' lower torque in order to strike his opponent having first blocked their attack.
 * 3) Madoka: Ikki's Third Sword, where Ikki receives an attack, taking the power, then he rotates himself around as if making a circle, he then send it back as a counter. Madoka has shown to be useful against more powerful opponents such as Ouma and Stella. He has evolved it in the finals of the 62nd 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 must be as loose as jelly, looser than normal, it is dangerous as even a moment of stiffness would result in his muscles to explode from the force being redirected.
 * 4) Shinkirou: His Fourth Sword 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: His Fifth Sword, a sword attack with a delayed effect, which uses slashes that has a certain amount of force and mechanisms to create wounds that wouldn't open until later on.
 * 6) Dokuga no Tachi: Ikki's Sixth Sword, where Ikki has all the muscles from his feet to fingers work together to create shockwaves, 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: Ikki's Seventh Sword and the fastest among his secret swords, where Ikki performs a sword swing at such speed, which exceeds a person's dynamic vision making it appear as if it were an invisible slash. At first, it required Ittou Shura but after learning Edelweiss' Swordsmanship, his reflexes and speed are fast enough to able to use this without using Ittou Shura.

Final Secret Sword

 * 1) Oikage: His Final Sword, a technique that Ikki developed to defeat Stella in the final match of the 62nd Seven Stars Sword Art Festival. After breaking the chains of fate binding him, he puts all the excess magic he gained to activate Ittou Rasetsu and uses a battōjutsu, in which he puts his right hand on the hilt pushing it, while his left hand is on the blade pulling Intetsu back, then unleashes a slash so fast that his shadow couldn't keep up with his movements.

Trivia

 * Ikki creating the Seven Secret Swords could either be a reference to his desire to participate in the Seven Stars Sword Art Festival to graduate and/or in preparation to win it using them.
