List of characters in order of appearance:


Prologue - Memories of Spring[]

In 2002, Mahiru asks Guren if they can get married in the future when they are older. Guren answers no, explaining that their stations are too different; as she's from the highest clan, while he is from a minor clan. People suddenly come by searching for Mahiru, and they find her with Guren. Out of rage, the group brutally beats him up before dragging a sobbing Mahiru away. After that, Guren begins to yearn for power so he can be with her. A decade goes by.

Chapter 1 - Welcome to High School, Jerk[]

The date is April 2012.

On their way to school, a now fifteen-year-old Guren warns his two retainers, Shigure and Sayuri, about the members/students of First Shibuya High School, as they all belong to the Order of the Imperial Demons. The trio agree to stay on guard no matter what before showing up. Upon their arrival, a student throws a cola can at Guren, which mimics the entire crowd to burst into laughter. Guren apologizes to Sayuri and Shigure, but he begs them to endure it. The pair reluctantly obeys.

Guren spots Shinya, who sends a Hiragi spell at him. He takes the attack on purpose and falls back unconscious. Once he awakes, he orders Shigure to retrieve him a new pair of clothes and enters school, starting the school year.

Chapter 2 - King of the Classroom[]

Guren is in Class 1-9 while Sayuri is in Class 1-1 and Shigure is in 1-2. Shinya Hīragi is in Guren’s class. He arrives late and then says he wants to help Guren bring down the Hīragi Clan.

Chapter 3 - Top of the Class[]

Mito Jūjō jabs at Guren while the principal gives the opening speech. Shigure and Sayuri move into Guren’s apartment against his wishes, and he encounters Makoto Kijima for the first time.

Chapter 4 - Reunited[]

The students spar against each other, and Shinya hits Guren so hard that he breaks several ribs, coughs up blood, and loses consciousness. Mahiru visits him in the nurse’s office, but he treats her coldly.

Chapter 5 - Deadly Wars and Supermarkets[]

Guren’s submissiveness to Seishiro Hīragi makes him lose respect from everyone in the class, including Shinya and Mito. Guren encounters Makoto Kijima for the second time, but a young boy named Mikaela addresses the man as "Mr. Saitō." After Saitō reveals that the Hīragi Clan is involved with forbidden magic and that there will be an attack in ten days, Guren sends a message to his father about it.

Chapter 6 - The Qualification Exams[]

The students fight students of other classes one-on-one in a tournament-style battle for their qualifying exams. Shigure fights Mito. Guren fights as poorly as possible and wins by "accidentally" hitting his opponent with a wild swing that knocks him out. Seishirō beats Sayuri severely and tries to strip her until Mahiru intervenes.

Chapter 7 - From Mahiru, with Love[]

Sayuri is hospitalized with Shigure looking over her. Guren forfeits his match against Seishirō, which leads the whole school to mock him. The Brotherhood of a Thousand Nights attacks and kills many students and teachers. Guren and Shinya fight Saitō and learn that Mahiru betrayed the Hīragi Clan. Guren and Mahiru fight, and she cuts his sword, Kujakumaru, in half.

Epilogue - The Last Spring before the End[]

After the Order of the Imperial Demons announces it put down the "terrorist group" that attacked them before, the school reopens. Shinya helps Guren get drenched in cola again when Shigure nearly stops the attack. Mito and Goshi become friendly with Guren, Sayuri, and Shigure.
