Still troubled over her inability to protect her best friend, Paku, who had quit the Exorcist lesson, Kamiki gets in a fight with Ryuji which results in the entire class getting punished by Yukio. Later after Yukio gives them a lecture about teamwork and leaves for mission, Rin and his classmates are attacked and cornered by the same Ghoul from the day before. While trying to help them, Rin learns that the monster was sent by one of the teachers who wanted to confirm that he was the son of Satan.
A two headed demon stands above Paku's body. Kamiki declares that she will save her friend. However, Paku tells Kamiki that she does not like her. Kamiki's fox spirits appear and tell her that they will not follow her. The demon appears behind her. Suddenly, Kamiki wakes from a bad dream. Rin is brushing his teeth, and Kamiki walks down the stairs behind him. After saying good morning, she tells Rin to not tell anyone she cried. Then she returns Rin's shirt. Rin is happy that she clean his shirt, but Kamiki replies she wash it because it is dirty. As soon as Yukio appears, he gives Paku a shot in her arm. Leaving Paku to heal, Yukio explains to Rin that the demon is a Naberius. When Rin asks Yukio how it got here due to the barriers, Yukio replies that sometimes demons will get through. In Paku's room, Paku tells Kamiki that both Okumura brothers are cute which makes Kamiki blush. Paku informs Kamiki that she will quit cram school. Kamiki is disappointed. Paku reassures her that she loves her the way she is.
On the roof, Rin is thinking about the words of the Naberius demon who told him a certain person sent him and his father's words. Suddenly, Shiemi pops in; Rin immediately hit his head with hers by accident. Shiemi calls him idiot. Afterwards, they do laundry. Shiemi explains that she wants to be some assistance. When Rin asks her why she wants to be an exorcist, she replies that she does not know yet. Back in class, a teacher speaks in German about the fatal verses. The female teacher calls up Kamiki who is still thinking about Paku. She then tries to recite the verse. The teacher asks Ryuji to do it. Everyone is amazed by Ryuji's memorization abilities. Rin calls him smart after all. Yet, Kamiki dismisses Ryuji's abilities and informs him that Aria are defenseless luggage. Ryuji walks up to her; Kamiki taunts him by mocking his dream to defeat Satan. When Ryuji asks her why she wants to be an Exorcist, Kamiki's flashbacks of fire and a woman briefly appears. She stutters and refuses to answer Ryuji's questions. Immediately, Ryuji grabs her and curses at her which Kamiki tries to slap him. Yet, her slap hits Rin who tells them to fight somewhere else.
Yukio appears and tells them to behave. In Yukio and Rin's dorm, the class all have stones on their laps. Bon explains it is a demon (ghost stones). Yukio explains that this exercise is to strengthen bonds and get everyone to work together. Finally, Yukio exclaims that an exorcist cannot fight alone. He explains that they should fight in teams, and they should support and cover their weaknesses. Yukio informs them that he will lock every entrance and be gone in 3 hours for a mission. After Yukio left, Rin reassures them that Yukio is a nice guy. Ryuji blames Kamiki then the two start to bicker. He tells her that she will scare everyone. Suddenly, the lights go out. Shima go out to open the door and closes it. With Shima still standing near the door, the Naberius demon smashes the door open. The demon splashes miasmi over them. Shiemi has her Greenman spirit sprout roots to keep the demon locked up against the wall. Yet, the demon keeps bashing at the roots. Shiemi and everyone else starts to cough due to the miasma. While Rin calls Yukio for help, Rin decides to lure the demon away. The demon with the flowered head shape chases off Rin.
Ryuji points to the other demon still present in the room. He tells them to kill it with chants. Ryuji states that he memorized all 20 chapters of fatal verses. Bon helps out by chanting 1-10 chapters. Ryuji wants to help out Shiemi whose energy is weakening due to the roots getting smash. As Bon and Ryuji chant, Shima has his staff ready. In the room with the fuses, Rin attempts to escape the demon and shields himself with blue flames. Igor appears with the knowledge of Rin being Satan's son. Suddenly, Shiemi collapses from the miasma; Shima protects his team. Back in the room, Rin realizes Igor is the one behind the attacks. Rin slashes the demon, and Igor retreats. Back to Shiemi and the others, she whispers that Kamiki is not herself. Kamiki regains her resolve and summons her fox spirits. She finally regain control of them and attacks the demon. Yet, the demon is not fazed by Kamiki's attack and grabs Ryuji by the head. When the lights go on, Ryuji kills the demon by completing the verse. As the demon dies, Ryuji is still in shock from the demon.
Rin barges in and asks them if they seen another demon. Rin tells them that he took out the demon and congratulates his friends for taking out the second one. Ryuji smacks Rin for being reckless while Kamiki thanks Shiemi (she still restricts her emotions). Kamiki thinks about Paku who is still sleeping.
After the credits, Yukio and Igor reappear in front of them.
