Ikki Kurogane vs Ouma Kurogane: Rematch

Ikki Kurogane vs Ouma Kurogane: Rematch is a fight between the Hagun Academy student Ikki Kurogane and the Akatsuki member, Ouma Kurogane, the brother of Ikki. It takes place prior to the finals of the Seven Stars Sword Art Festival.

Prologue
Ikki, who is training for his match against Stella Vermillion, battles multiple students, including Touka Toudou and Yudai Moroboshi, defeating them all. He, however, is challenged by one more opponent, his brother Ouma. Ouma was called by Ikki to come and fight him, with Ouma quite surprisingly agreeing to come. Ouma, who had previously been beaten by Stella, doesn't believe that Ikki will be able to defeat her, but he still wants to see how strong Ikki is. Ouma is a perfect opponent for Ikki to face, as he is also an A-Rank like Stella and possesses similar abilities. If Ikki cannot beat Ouma, he will not be able to win against Stella.

Battle
After they manifest their Devices, Ikki and Ouma charge towards each other, with Ikki creating multiple afterimages with his fourth secret sword technique, Shinkirou. Ouma easily cuts down the afterimages, which was planned by Ikki, who uses the opportunity to attack the defenseless Ouma. Ouma though pushes Ikki back with a shoulder charge, which Ikki manages to block with his Device.

While Ikki recovers, Ouma rushes towards him, delivering multiple fast slashes at him. This is a secret technique of Kyokujitsu Isshin-ryuu, the sword style of the Kurogane Family, called Kyokujitsu Isshin-ryuu · Retsu no Kiwami - Amatsukaze. This attack delivers 108 continues slashes, which are both strong and fast. This technique is, however, what Ikki was hoping for, as he plans on using a gap in the slashes, to attack Ouma. When a small gap appears, between the 57th and 58th, Ikki uses his seventh sword technique, Raikou, an extremely fast strike, which Ikki hits Ouma's side with. This throws Ouma off balance, stopping his attacks. Ikki then immediately uses his sixth sword technique, Dokuga-no-tachi, which delivers damage through vibrations and should strike through Ouma's steel-like body. However, Ikki's attack is stopped by Ouma's Tenryuu Armor, an armor made of wind, blowing Ikki back.

Ouma uses his Noble Art, Shinkuuha, sending a slash of wind towards Ikki. Ikki uses his first sword technique, Saigeki, using the force of landing on the ground to propulsion himself towards Ouma and destroying the wind blade with his powerful strike. Ouma then takes a stance, that suggests that he will be using his fastest attack, Kyokujitsu Isshin-ryuu · Jin no Kiwami - Amaterasu, which is faster than Ikki's Saigeki, meaning that it will hit Ikki first. However, when Ouma releases Amaterasu, Ikki stabs his blade into the ground and uses it as a pole vault to jump over Ouma. Ikki then kicks the ceiling of the arena to launch himself towards Ouma and attack with another Saigeki. As Amaterasu is a move that requires the user to give everything they have, it leaves them open to other attacks after using it. Ikki's strike pierces through Ouma's wind armor and hits his clavicle. Ikki, who has seen through Ouma's muscles, knows that his blade should pierce him. However, Ouma protrudes his muscles, before Ikki's blade hits him, stopping the blade and catching it between his muscles. Ikki attempts to pull out his sword, but Ouma grabs him and throws him on the ground. Ikki uses an ukemi (art of falling down) to distribute the impact of the fall, but his posture is left bad. While Ikki is down, Ouma delivers a powerful slash towards him, Ikki swings his sword to receive the attack, although he shouldn't be able to block it due to his bad posture. Surprisingly, however, Ouma gets pushed back to the edge of the arena.

The people watching are surprised and unable to understand what happened, with even Touka and Yudai being confused. Ouma though understands what has happened, Ikki having used a sword technique to redirect the force of Ouma's attack back at him. Ouma claims that Ikki is just using his regular trickery, but Ikki says that he will use any means to achieve victory against those that are stronger than him, noting that Ouma is the one that got pushed back. Ouma wonders if Ikki does, in fact, possess his own unique strength, asking if Ikki is satisfied with just pushing Ouma back. Ouma then gets back to the arena and unleashes a tornado of wind around his blade, telling Ikki to get ready as he will now use everything he has to defeat Ikki. Ikki is surprised that Ouma will give his all but decides to face him, as he notices that he is no longer worried about facing Stella.

Epilogue
The outcome of the match between Ikki and Ouma is left unknown, but Ikki arrives to the finals of the Festival, with no major injuries. Ikki goes on to face Stella in the finals, using the same technique he used against Ouma, Madoka, the third secret sword technique, against her.
