First Day of School

 * Guren Ichinose, Sayuri Hanayori, and Shigure Yukimi begin their first day of school at First Shibuya High School.
 * Guren has a bottle of cola thrown at his head before being attacked by Shinya Hīragi.
 * Shinya attempts to befriend Guren in the classroom.
 * Mito Jūjō strikes up a conversation with Guren during the assembly.
 * Mahiru Hīragi gives her speech as freshman class representative.
 * 19:30 JST: Guren, Sayuri, and Shigure go to the apartment complex.
 * Guren speaks with his father.
 * Guren is attacked by Saitō, who at the time, uses the alias of Makoto Kijima and calls himself an assassin from the Brotherhood of a Thousand Nights.

A Day of School

 * In a magic duel, Guren is punched by Norito Goshi which triggers a wave of laughter from the other students. Mito and Norito then get into a fight.
 * Shinya attacks Guren with all his might, severing an artery and sending him to the nurse's office.
 * After ten years, Guren reunites with Mahiru face-to-face.

A Day of School

 * The teacher announces the qualifying exams while Shinya tries to figure out if Guren was indeed as weak as he says he is.
 * When Guren, Sayuri, and Shigure were going to head home, Guren bumps into Seishirō Hīragi who then tries attacking Guren but is stopped by Shinya.
 * In irritation, Seishirō changes targets and attacks Shinya instead, asking him about Guren's strength.
 * Shinya informs Seishirō that Guren is weak and loses all respect for Guren while he was at it.
 * On the way home, Sayuri and Shigure apologize over and over again for being weak while Guren quiets them and begins processing the information about Seishirō.
 * Guren and Saitō meet again and have a discussion where Saitō asks for the cooperation of the Imperial Moon which Guren denies.
 * Sayuri and Shigure complete their shopping at the supermarket before Guren tasks Shigure with a mission. He then writes a letter to his father explaining the situation with the Brotherhood.

Day One of Qualifying Exams

 * 08:00 JST: The qualifying exams begin.
 * Shigure and Mito's match ends with the latter's victory.
 * Norito easily defeats a boy in his match and Shinya defeats a high-ranking spell cast by his opponent with ease.
 * Shinya questions Guren, asking if he knew what he had done to which he doesn't bother to stop to listen to an answer (Guren does know what happened, however).
 * Directly after, Guren is called for his match and defeats his opponent with what seems like a lucky wild swing. Meanwhile, Norito scoffs and Mito accuses Guren of his weakness, scolding him for having Shigure serve him while he himself was incompetent.
 * Shigure defends her master which sparks more ridicule. Guren then spots Mahiru, who had grown exceedingly powerful, easily defeating an opponent that was at Mito's level.
 * On the other hand, Seishiro was dishing out a beating to Sayuri, to the point where she loses consciousness partway. Seishiro taunts Guren who immediately tries to go and fight him but is stopped by Mahiru who proceeds to fight Seishiro off and save Sayuri, handing her to Guren before berating him on his inability to protect the girl.
 * Guren, with Sayuri in his arms, and Shigure proceed to leave the area to which Seishiro catcalls them, resulting from an explosion of laughter from the students. In his mind, Guren contemplates how great would feel to simply drop his ambitions and kill all of them.

Day Two of Qualifying Exams

 * Guren's class has been undefeated ever since the start, causing Guren to wonder if what the Hiragi were doing at this school was any different from the Thousand Nights. Shinya interrupts Guren's thoughts, inquiring about Sayuri, to which Guren replies that she had been hospitalized, and suggesting that Guren forfeit his match against Seishiro which results in Shinya's opinion of Guren to lower yet again.
 * When Shinya enters the ring and Guren reveals his forfeit, both Mito and Norito blow their top while Seishiro laughs at the top of his lungs which spread like wildfire among the other students.
 * The Attack on First Shibuya High School begins.
 * Guren notices a red ray of light, aimed directly at Mito and Norito, and with a split-second decision, he shoves them aside, saving them from the explosion.
 * The war between the Hiragi and the Thousand Nights begin, much earlier than what Saito had told Guren (he never believed him in the first place).
 * Saito himself appears and Seishiro attacks him, only to be almost killed then blown away to safety by Guren's kick, before Guren himself attacks Saito, unintentionally revealing his true power to Shinya to which Guren asks him about his ambition to bring down the Hiragi.
 * Saito attacks them again but Guren and Shinya easily avoid them before the two began bickering about which of them was stronger while Saito laments about his luck, having to deal with two of the seven dangerous targets himself.
 * Saito begins attempting to negotiate with the two teens to which Guren doesn't buy it and tortures him to get a true answer.
 * Through hints given via Saito's way of talking, Shinya figures out who the traitor is and charges away into the smokescreen around them, seconds before Guren figured out for himself who the traitor is.
 * The attack moves into phase two, with the traitor, Mahiru Hiragi, pretending to be ' captured ' while Guren continues to torture Saito.
 * Guren fights Mahiru, who reveals to him that she had begun perfecting Cursed Gear. Mahiru's human personality briefly breaks through, crying to Guren that she had failed the experiment which her demon obviously rebuked. Mahiru then reveals about the Apocalypse of Christmas Day. After Mahiru shows the power of her Cursed Gear by easily bisecting Guren's Kujakumaru, Saito and Mahiru both retreat but not before Mahiru stresses how much she loves Guren.
 * Once the magic smokescreen was removed, Guren was able to survey the carnage brought about by the Thousand Nights' attack. Mito immediately hugged Guren which sparked Norito to make a joke about how close they were to each other to which Mito only acknowledged by stating that he was alive, resulting in Norito questioning Guren's luck with girls. Mito then questions how Guren survived to which his reply earned him another exasperated response from them.
 * Shinya returns and he falsely claims that Mahiru had been kidnapped which Guren takes it as Shinya truly hates the Hiragi. When discovering that Guren was still keeping up his act of incompetence, Shinya sighs in complete exasperation.

Another Day of School

 * Sayuri had recovered from her injuries and insists that she stick by Guren's side.
 * As usual, Guren had another bottle of cola thrown at him but Shigure intercepts. Shinya, however, helps Guren keep his act of incompetence and interferes with Shigure's interception allowing the bottle to strike true.
 * Mito begins berating Guren then berates the other students who find it odd that Mito was standing up for Guren.
 * Norito also appears, scaring off Guren's bullies, but Guren disagrees, telling them off with the reason that he needs no friends.
 * Mito again tries to invite Shigure to her compound to have a talk with her father while Norito hits on Sayuri.
 * Guren sighs as he contemplates on why they were acting like this when they were in the middle of a war.

December 25

 * The Catastrophe begins.
