Shizuku Kurogane and Nagi Arisuin vs Amane Shinomiya

Shizuku Kurogane and Nagi Arisuin vs Amane Shinomiya is a fight between the Hagun Academy students Shizuku and Nagi against the Akatsuki member Amane. It takes place just before the actual quarter-finals of the Seven Stars Sword Art Festival, which was supposed to be between Shizuku and Amane.

Prologue
Shizuku is seen talking with her friend Nagi, about her upcoming match against Amane, who has the ability Nameless Glory which can make all his wishes true. Shizuku explains that because of Amane's ability, she can't win against him in a match, so she will ambush him before the match. The surprised Nagi comments that this kind of action would get Shizuku disqualified from the Festival. Shizuku though doesn't care, as she simply wants to protect her brother Ikki, from Amane, by rendering the Akatsuki member unable to fight. Nagi decides to help Shizuku, despite that it would most likely get him in trouble as well.

Before the start of the quarter-finals of Block D, Shizuku and Nagi sneak into the waiting room, where Amane is waiting for his match.

Battle
After sneaking into the waiting room, Shizuku immediately uses her abilities, to launch multiple ice spears into Amane's body. Despite the spears piercing his limbs and skull, Amane gets up, as his Nameless Glory makes the damage he received none lethal. Shizuku is greatly shocked by Amane's recovery.

Nagi then uses his Shadow Bind, to immobilize Amane, but just then the lights in the room temporarily go out, rendering Nagi's shadow manipulation abilities useless. Amane then uses his Device, Azure, to pierce Nagi's body with multiple swords, rendering him unconscious.

Amane proclaims he doesn't blame Shizuku or Nagi for attacking him, but is instead very excited. He declares that he admires Shizuku's love her brother, and because of this he will give her a special chance. If she can defeat him in a minute, his ability will ensure that no one will find about this incident.

Shizuku tries attacking Amane with her Device, but Nameless Glory, makes her trip and miss her attacks. Amane says that he simply wished to win the fight, marking that anyone could make mistakes while fighting. Amane then uses his swords to slash at Shizuku, causing her sight to be comprehended. Shizuku though refuses to give up and uses her Byakuya Kekkai to summon a fog, which covers the entire room. Despite not seeing Shizuku, Amane, with the help of Nameless Glory, throws multiple swords at her, which all pierce her to the wall. This renders her unable to continue fighting, just as a giant monitor in the stadium above starts to broadcast footage from the waiting room.

Epilogue
After winning the fight, Amane announces to everyone about Shizuku's deep love for her brother, which goes beyond the the love between siblings, humiliating Shizuku in front of everyone. Before Amane can go any further, he is stopped by Stella Vermillion, who rescues Shizuku.

Both Nagi and Shizuku are healed, but Shizuku is disqualified from the Festival, while Amane advances to the semi-finals, where he will face Ikki.
