Stella Vermillion vs Ouma Kurogane: Rematch

Stella Vermillion vs Ouma Kurogane is a fight between the Hagun Academy representative Stella Vermillion and the Akatsuki member Ouma Kurogane. It's one of the semi-final matches of the Seven Stars Sword Art Festival.

Prologue
Ouma Kurogane, the brother of Ikki, has entered the Festival for the single reason of fighting Stella. He wants to do this, in order to reach an "evolution", so he can fight with the strongest Blazers in the world. And now he has finally reached his goal, in the semi-finals.

After their brief encounter during Akatsuki's attack on Hagun Academy, Stella has been training with Nene to face Ouma, who previously defeated Stella. After her training Stella single-handedly took out most of the contestants of her Block.

Just before the start of the match Ikki, who is watching the match, is accompanied by Tohka and Kanata, who have arrived to watch the battle between the two A-Rank knights.

Battle
As the fight begins, Stella immediately shoots Ouma with her Broken Arrow, but her attack is easily countered by Ouma's wind. The fighters then clash, as Stella tries using her Empress Dress, to protect herself. Ouma though uses his wind in a similar manner, surrounding himself with wind. The clashing of their blades creates a huge sound impact, which knocks the audience in the front rows back.

Stella then uses Satan Fang, which shoots seven fiery dragon heads at Ouma. Ouma blocks the attack with Fuujin Kekkai, which creates a tornado around him. However, as Ouma blocks Satan Fang, Stella sneaks behind him with Flame Veil and tries hitting Ouma. Despite directly hitting Ouma, Stella's attack doesn't leave a scratch on Ouma, while Stella herself injures both of her arms. Ouma then kicks Stella, launching her back, and damaging her internal organs. Stella though rises, declaring that she has figured out the secret behind Ouma's body, which is his Tenryuu Armor. With the Tenryuu Armor, Ouma surrounds his body, with extremely high pressured air, which in turn increased the densities of his body and muscles, making his skin comparable to steel.

After Stella realizes Ouma's secret, he decides to tell her about his encounter with "Tyrant", the leader of Rebellion. During his travels through the world, Ouma confronted "Tyrant", who brutally defeated him. Ouma only survived thanks to Edelweiss, who protected him. Because of this, Ouma wants to fight Stella, to reach his "evolution".

Ouma then releases his Tenryuu Armor, which greatly increases his speed. Ouma then proceeds to attack Stella with his Shinkuuha, which Stella barely can evade. She is then punched by Ouma, blowing her into a wall. Despite being gravely injured, Stella rises and asks why Ouma wants to become stronger. Ouma answers that if he was stronger than everyone else, it would make him feel really good. Stella compares Ouma to Ikki, telling Ouma he is the second opponent she truly respects. Stella then stabs herself with Laevateinn, activating her true ability, Dragon Spirit.

Nene, who is the commentator for the match, remembers her training of Stella. It shows Stella fighting Nene, who says that Stella doesn't lack power, but pride in her own abilities. When Stella is about to give up, she remembers her past, which reminds her of her belief that as the person with the most magic power, she should be the strongest of all. Stella then for the first time reaches Dragon Spirit, revealing the true nature of her abilities are in fact conceptual manipulation of dragons, instead of elemental manipulation of fire. Back in the present, after activating her Dragon Spirit, Stella receives an immense boost in her power and speed. She manages to overpower Ouma, who is unable to stand up to the immense power of Dragon Spirit, even with his Amaterasu, which is the fastest technique he possesses. As his final effort, Ouma launches his Kusanagi at Stella, who responds with Katharterio Salamandra. Ouma is defeated by the overwhelming power of Stella's attack.

Epilogue
Because of losing Ouma is eliminated from the Festival, while Stella advances to the finals. Stella's new power also greatly shocks everyone, even troubling Ikki, who wants to face her. Before that though he needs to defeat the remaining Akatsuki member, Amane Shinomiya.
