After Desperately Deciphering and Utilizing a Mysterious Magic Book, I Created a Slave Harem! Popular Idols, Classmates, School Girls, All These Beautiful Girls Are Mine! - Chapter 1 - Inheritance From an Old Relative

Chapter 1 – Inheritance From an Old Relative

　I, Saida Atsushi, was struggling to catch my breath in front of a certain apartment building about an hour away from my house by train and on foot.

(Calm down! The preparations are perfect!)

(Iroha-sensei’s emotions have already been fiddled with with mental magic, and I’ve perfected my lewd crest magic on her as well! …I think…)

(It’s okay. Today is the day I’m graduating from virginity! And I’ll make Iroha-sensei my sex slave!!)

　I desperately control my heart that seems to be raging with excitement and start walking toward the entrance of the apartment. All while believing that my future will bring about tremendous changes…

　+++

　When I was in the fifth grade of elementary school, an old relative who lived nearby died. He was an old man who was famous as a freak and hated by his relatives.

　Even from my point of view, he was an old man with many secrets that I didn’t really understand, but for some reason he got along well with me and was very affectionate to me.

　He was strangely well-financed, and he often gave me pocket money, so I took advantage of this and continued to go to his house, where he lived alone.

　A few days before he died, I was handed a sealed paper bag when I left. He told me to open it when he died.

　A few days later, when I came home from elementary school, my mother told me that he collapsed and passed away. I remembered what happened a few days ago, and I remember being surprised that he knew he was going to die.

　Various other things were being processed, disposed of, etc., as if he knew he was going to die, and the adults in the extended family were creeped out.

　While my adult relatives were busy with the funeral, I was free as a child, so I decided to open the paper bag that that old man had given me. When I looked inside, it looked like books.

　When I took them all out, I found several old notebooks, about ten old books, and an ordinary envelope. First, when I checked the envelope, it was a letter addressed to me from the deceased old man.

　When I read it, I found it to be a joke. The old books were magic books and the notebooks contained the contents of the parts of the magic books that could be deciphered.

　The old man had mastered precognition magic from this magic book, and it seems he used it to make money by gambling. Unfortunately, he was in his later years when he obtained the magic book, so there was a description that he couldn’t spend time analyzing it, leaving the rest to me.

　As I was reading it, I thought that the old man would ridicule me with such things, and at the end he said that I wouldn’t believe him, so he would clear my suspicions, and the method was written. The method was also about gambling, and specifically, the winners of all the horse races held on the weekend were described.

　I thought it would depend on the weekend whether this was a joke or not, so when I checked the results in the newspaper, I was surprised to find that all the races that were on the list were correct. Thinking that this might be the real thing, I started reading the magic books and notebooks seriously.

　The old man deciphered the subtitles, so I deciphered the items that I was interested in first. Using his notebooks as a reference, I first searched for magic that would improve my grades in school.

　Over the course of several months, I was able to decipher the magic that temporarily increased my brain speed and memory, and made it mine. While using that magic on myself, I proceeded to decipher it, and this time I deciphered and mastered the magic that grew my brain and memory.

　The former has a large degree of increase, but returns to normal once the magic wears off. The latter, on the contrary, has a very small degree of rise, but the raised portion doesn’t fall.

　While using them, I increased the speed of deciphering, and continued to master new magic. There was magic that grew physical ability, magic that understood other people’s emotions, magic that slightly manipulated other people’s emotions, and many other types of magic.

　While deciphering the magic book, I became a junior high school student, and my interest in women increased. I also mastered and used magic that would help me to become more attractive as a man, such as growing taller and releasing male pheromones.

　In the second year of junior high school, my grades improved remarkably thanks to magic that grew my brain and memory, and I was recommended to aim for a special advanced course at the top private high school attached to K University in the area. My parents were also interested, and one day they brought a tutor.

　Soejima Iroha. She is a first-year student in the Literature Department of the private K University and a graduate of the special advanced course attached to the private K University high school that I was recommended to.

　However, at first glance, she didn’t look like a college student at all. She looked like a cute, slender girl who didn’t seem to be taller than 150 cm, and would come as a junior high school student.

　Her face could be said to be sufficiently beautiful, but it was expressionless, and she looked at me with cold eyes. When I secretly used emotion-detecting magic, I concluded that she disliked men because she had a strong dislike only for me and my father.

　In the end, she was asked to work twice a week for my first semester. I didn’t have any subjects that I was particularly bad at, so I felt like she was asked to look at them in general.

　I lusted for her beauty, and when she was a tutor, I continued to use magic to increase her love and affection for me. Luckily, the other students that Iroha-sensei was in charge of as a tutor gave up on being affiliated with K University and withdrew, so I was the only one left who she was tutoring and was able to continue after the second semester.

　By the time I was promoted to the third year of junior high school, she had softened a lot, probably due to the effect of me continuing to use magic on her. When I asked Iroha-sensei about her high school, she said that the Special Advancement Course was a place where all she had to think about was studying, so she didn’t have many good memories.

　There were two other courses, a regular course and a performing arts course, which were joint classes and looked like a lot of fun from her point of view. She advised me that I could go to a good college in the regular course, as she had seen in the past year, so a regular course is also possible.

　Before the entrance exam, Iroha-sensei even gave me a big smile and made me homemade sweets to thank me for my hard work. In the end, I decided to take the high school entrance exam for the regular course at a private high school affiliated with K University because I would be in the same class as the performing arts course.

　My parents and junior high school teachers strongly encouraged me to take the special entrance exam, but I refused because I dreamed of being in the same class as cute idols in the performing arts department. Well, I am a man.

　As it had been determined that I would pass the examination if I performed as well as I normally do, I passed without any problems. This was thanks to a magic book of unknown origin.

　Iroha-sensei was especially pleased. According to her story, it seems that the tutor who was in charge of the student who passed the super difficult high school will get a gold medal.

　Perhaps because of this, she agreed to treat me to a home-cooked meal, just the two of us, as a celebration of my passing the entrance exam. However, because our schedules conflicted, the celebration took place on a Sunday in early April, just before the entrance ceremony, so it became a celebration for both the graduation from junior high school and the entrance into high school.

　Let’s go back to the beginning here.

　Right now, I’m standing in front of Iroha-sensei’s room and about to ring the intercom. Thinking about the future, I couldn’t calm down my excitement, so I used sedative magic on myself and managed to calm down.

　When I pressed the button to ring the chime, I could hear a cute voice from the intercom.

“Yes? May I ask who’s calling?”

“Good morning. It’s Saida.”

“I was waiting. I’ll open it right away.”

　With the sound of a key being unlocked, the front door opened. Iroha-sensei came out from inside and gave me a bright smile.

　Recently, my height has exceeded 170 cm, and she is short at 148 cm. As a result, I’m facing her while looking down.

“Welcome, Atsushi-kun.”

“…Thank you for inviting me today.”

“It’s because Atsushi-kun is the main character today.”

“Is that so?”

“Then hurry up and come in.”

“Yes. Excuse me.”

　Iroha-sensei invited me into the room while swinging her straight black hair down to her shoulder blades. Hiding my dark sexual desires, I entered the room that smelled of her daily life.

　Iroha-sensei locked the door from the inside and proceeded to the back of the room. I slightly disturbed my breathing because we were alone in a closed room, and followed that small back into the room.
