Thor und Julie müssen sich einem unerwarteten Hindernis am Ende ihres Probekampf-Turniers stellen. Julie spricht Thor auf jemanden in seiner Vergangenheit an.
On the day after the official duos have been determined, Rito Tsukimi informed her students in the classroom of the upcoming New Blade Battle which will be held in the next couple of days. In preparation for the battle, Tooru and Julie trained themselves and practiced their combat skills with their Blazes. Later at the sport stadium, Tooru found Miyabi, exhausted, running along the track when she suddenly collapsed. Unconscious, she is picked up and carried back to her dormitory by Tooru. On the way, she wakes up and Tooru encouraged her to keep training in order to become stronger. On the next day, late afternoon, the New Blade Battle starts at 5 o'clock. The duos have 2 hours to survive and eliminate all other duos to win the battle. As the battle continues, the defeated duos are eliminated from the battle. The three last duos remaining are Tooru's, Tomoe's and Tora's. Tomoe and Miyabi are eventually defeated by Tooru and Julie. Tooru and Julie continue and move on to find the other remaining duo. By the time Tooru and Julie gets there, Tora and his partner are found injured lying on the floor. Momentarily, Rito shows up and suddenly attack Tooru, revealing that she is the person who injure Tora and Tatsu. Then she explains that it is her duty to eliminate any student who is not up to the task. The fight between Tooru, Julie and Rito carries on. Afer learning from Rito that by breaking enemy's Blaze the enemy's soul will be damaged, Tooru uses his Mjolnir punch to break Rito's Blaze and end the fight. The next morning, still recovering from the injury, Tooru and Julie sit at the table and have their usual morning tea. They are then visited by Tomoe and Miyabi who bring them refreshments. That night, Tooru wakes up from the repeating nightmare about the past incident. The noises wake Julie up as well. She shows him the scar on her back, revealing that she is an Avenger like Tooru.

Quel objectif se cache derrière le désir de Tor d'être dans cette académie ?
