List of characters in order of appearance:


Krul Tepes declares war against the Japanese Imperial Demon Army, stating they have committed the sin of experimenting on the Seraph of the End. Mikaela Hyakuya swears to himself to rescue Yu.

Yu insists on receiving his cursed gear

In a separate location, Major General Shinya Hīragi begins a report at a meeting with the head brass, but Guren is asleep. Another soldier nudges him to wake him, and he stands up, yawning, then asks if this boring meeting is over yet. Despite Shinya's attempts to make Guren behave, Guren voluntarily walks out while members of the Hīragi family including Seishirō Hīragi mock him. Leaving the meeting hall, which appears to be underground, Yu attempts to kick Guren and insists on receiving his Cursed Gear. Catching his foot, Guren easily defeats him yet decides to finally give Yu his Cursed Gear and send him out into the field, partially to keep him from being noticed by the Hīragi family. He knocks Yu out by kicking him on the head and walks away while stating that idiots are tiring.

Yu meets Shinoa in the cafeteria

Yu returns to a cafeteria where Shinoa Hīragi is finishing her meal. She asks him if he skipped class by getting in a fight, and he denies it. Shinoa then congratulates him on being permitted to get an official demon weapon, which leads Yu to tell her to not ask about it if she already knew what he did.

Mika reaches the house he shared with the other children from the Hyakuya orphanage

Elsewhere, Mika watches as a vampire plane disembark from the underground city, and Ferid Bathory leans against the guard railing a few feet away. Ferid mentions that Mika can now save his precious angel, but Mika merely snubs him and walks away without giving any response. Ferid states that he has high hopes for him. Mika walks through the streets of Sanguinem as children rest in street corners or in their homes. He wanders until he eventually reaches the house he shared with the other children from the Hyakuya orphanage. As Mika places his hand on the door a child opens it from inside and sees Mika before freezing in terror. Mika smiles and tells him it is alright and moves to pat his head, but an older child pulls him back to protect him. Mika leaves, pausing at the end of the steps he does not look back before heading back down the street again.

Sayuri returning test papers

In the classroom, Sayuri Hanayori returns the test papers to the students and claims the scores will have an impact on which level of cursed gear they receive. Yu sees his score of zero and quickly moves to hide it, but Shinoa notices and steals it too quickly for him to protect. She prances around the room with Yu attempting to regain his paper. When he finally catches her, she reveals that her hands are empty. A group of students look at Yu's test score and marvel at the zero and how everything was written with Hiragana. Yu takes it back and shoves it in his pocket.

Yu and Kimizuki gets into a fist fight

Yoichi Saotome wonders if Yu might be better at English and Latin since he grew up in a vampire city. Shihō Kimizuki asks if he has shit in his head, and Yu asks him what scores he earned. Kimizuki reveals perfect scores in English, Latin, and Japanese spell craft. When Yu and Kimizuki get into another fist fight, Guren walks into the classroom and asks why it is always so noisy. Seeing him, Yu demands a cursed gear, and Kimizuki would also like to know why Guren abandoned their classroom for ten days.

Demonic aura

Guren asks Sayuri if those children might be ready to form a contract even if they have not completed their training, and she states that Yoichi is surprisingly more stable than the others. Guren draws his sword and pierces the classroom floor, flooding the room with a demonic aura. Most of the students collapse, and Sayuri has to use warding spells to withstand it. Yoichi and Shinoa bear it without difficulty, but Kimizuki and Yu struggle more. A pair of male and female students were also able to endure the power, but they collapse shortly afterwards.

The group expresses their doubts

As they head to the ceremony room, Sayuri expresses her doubts about Yoichi having a strong enough heart for the demon. Guren asks if Yoichi is willing to give his life for revenge. Yu advises Yoichi to quit now which Kimizuki agrees with. Yoichi experiences a flashback of his sister's death and considers that he cannot stop hearing it no matter how hard he covers his ears. He decides to continue.

Guren explains the contract ceremony, and the three boys walk up to the weapons they choose. Yu draws a green sword.
