Light Novel Volume 1/Summary

Prologue
Ordinary Japanese third-year high school student, Kazuha Oda, recounts her life up until her untimely death. She has a secret crush on her childhood friend, Tooru Saitou, but can't muster the courage to confess to him. She learns that her friend, Airi Tanaka, also has a crush on Tooru, and is planning to confess to him after school on the school's rooftop. Deciding that she wasn't okay with this, she races to the school rooftop just in time to see Tooru and Airi lying in a pool of blood, stabbed by a mysterious blond man. Kazuha is also stabbed and pushed off the roof, but not before hearing the blond man say the word "Maydare."

Chapter 1: Makia and Thor
In the southern Kingdom of Ruschia located in Maydare, Makia O'Drielle wakes up on the morning of her eleventh birthday after she dreamed about Kazuha Oda, though she doesn't know who she is yet. She travels to the port town of Kartedt with her father to pick out a birthday present. While at a curio shop, she witnesses a slave boy using magic without any tools or incantations. She attempts to talk to him, but he brushes her off. She decides to break the chains on his feet, but is caught by his master. Her father saves her just in time and Makia tells him that she wants the boy, arguing that by taking him in as a pupil, his magic potential will help save their declining house. After some hesitation, her father agrees and they buy the boy as Makia's birthday present. The boy refuses to tell them his name, so Makia names him Thor.

Back at the O'Drielle manor at Deliafield, Thor is given a bath and a haircut. He is resentful and suspicious of Makia's intentions, but Makia tells him that she chose him because she doesn't want to see his magic potential go to waste as a slave. She tells him the story of the Hero of Fraxinus, who killed the White Sage, Black Demon King, and Scarlet Witch―the ancestor of the O'Drielles―in the great war that engulfed the world five hundred years ago. She tells him that he can use his magic to influence the world just like those great magicians and that they can do it together. Thor decides to take her up on her offer.

Chapter 2: The Salt Forest
Half a year has passed since Thor is taken into the O'Drielle family. His magic powers have developed at an astonishing rate and he is training in swordplay with the family knight, Godwin. Makia is astonished by how quickly he is growing but is also determined not to lose to him. One day, Makia decides to visit her grandmother in the Salt Forest in the northernmost part of Deliafield and brings Thor along with her. Makia introduces Thor to the unique flora and fauna of the Salt Forest and the two have a picnic. Thor gets injured while protecting Makia from a fall when they are collecting things that could only be found in the Salt Forest, causing Makia to cry and heal him with a potion. Thor remarks that Makia isn't like how he expected her to be, as she is a crybaby but also a hard worker.

The two wander into a patch of red anemones on their way to Makia's grandmother's house and Makia is attacked by a group of Ribito frogs, drawn to her high body temperature as a 【Fire】Blessed Child. They are saved by Makia's grandmother Camellia, who leads them to her hut. Thor asks why she lives in this forest hut instead of the O'Drielle mansion. Camellia explains that Scarlet Witch was born and raised in this hut, so she wants to learn more about her. She tells them that even though the Scarlet Witch is now known as the "Worst Witch in the World," the history books don't say that she actually had an impossible love. On the way home, Makia asks Thor if he has ever been in love.

Chapter 3: The Night of the Meteor Shower
Three years have passed, and Makia and Thor have become inseparable. While in Delhague, Ruschia's third-largest city, the two help apprehend a purse snatcher. For this, they are rewarded by Duke Bigreitz, the duke of the city and Makia's father's employer, with access to the star observation tower next to it. Makia overhears the duke and her father discussing plans to enroll Thor into the knight academy and adopt him into the family as a son-in-law. For the first time, Makia realizes that she has feelings for Thor.

At night, Makia and Thor head to the star observation tower. Thor notices Makia's distracted behavior and gives her a pair of red crystal earrings for her fourteenth birthday. Makia tells Thor about what she overheard. Thor is horrified as he believes it is too early for her to settle on a marriage partner, since she still hasn't seen the world yet. Before Makia could confess her feelings, a meteor shower begins to make its way across the sky. Makia suddenly gets a headache and recalls her past life memories as Kazuha Oda. She begins to wonder whether or not Thor is actually the reincarnation of Tooru Saitou. Meanwhile, Thor gets a strange crest on his chest, making him feel an excruciating pain. Makia takes him to her father and Duke Bigreitz, who both realize the meaning of the crest on Thor's chest. Makia is sent to her room.

The next day, Makia's father tells her that Thor has been chosen to become one of the four Guardians who will protect the Savior who has arrived from another world. Thus, in accordance with the law, Thor is sent to the capital Miladriede with the backing of the Bigreitz Family, who has adopted him. Makia tries to chase after his carriage, but couldn't catch up. Later, her father tells her the legend of the Savior, whose arrival in Maydare is signalled by a meteor shower. Makia finally realizes that Thor is no longer her knight.
