Ikki Kurogane and Stella Vermillion vs Ascarid

Ikki Kurogane and Stella Vermillion vs Ascarid is a fight between the Hagun Academy students Ikki Kurogane and Stella Vermillion against the fourth ranked Mage-Knight in the KOK A-League, Iris Ascarid. It takes place just after the Seven Stars Sword Art Festival.

Prologue
After the finals of the Festival, Ikki and Stella are called to attend in a meeting between Kurono Shinguuji, Nene Saikyo and Bakuga Tsukikage. Once Ikki and Stella arrive though, they are suddenly ambushed by a Blazer wearing black armor, with a halberd as their weapon.

Battle
As the mysterious knight attacks them, both Ikki and Stella realize that the attacker has immensely strong, possessing physical strength comparable to Ouma Kurogane. Stella activates her Katharterio Salamandra, directly hitting the mysterious knight. Despite getting directly hit with one of Stella's strongest attacks, the mysterious knight remains unschated. Ikki than attacks the knight with his sixth secret sword technique, Dokuga no Tachi, which is supposed to strike through armor. The knight though still doesn't take any damage.

The armored knight then rotated their halberd, creating a whirlwind, which strikes Ikki. However, this is revealed to be nothing but an afterimage created by Ikki's Shinkirou. Ikki and Stella then attack together with Ikki using Saigeki, while Stella uses a powerful slash. This attack is called Tsunoou by Ikki and Harmonic Bullet by Stella. Even against the combined power of Ikki and Stella the knight still remains uninjured.

Just as Ikki and Stella are about to use Ittou Shura and Dragon Spirit, the fight is stopped by Kurono, who enters the room, along with Nene and Bakuga.

Epilogue
Kurono explains that the knght in black armor, is actually Ascarid, the fourth ranked Mage-Knight in the KOK A-League., whose ability makes him able to negate all injuries. Ascarid wanted to test Ikki's and Stella's strength, which Kurono, Nene and Bakuga accepted, as they wanted the young knights to face the power of a world-class knight.

After Ascarid takes her leave, Ikki and Stella are told about Desperados, powerful beings that have broken the chains of faith, as well as the horrifying visions that Bakuga has seen.
