Using a Mysterious Spellbook Ended Up Creating a Slave Harem - Chapter 41

Summoning Magic

On the Sunday one week after my first date with Kojina-san, I am currently practicing a magic spell that I'm using for the very first time. Since my family is out and I'm all alone at home, I shut myself in my room and drew a magic circle on the floor using mana.

"Come forth... Lesser Demon..."

In response to the powerful words I uttered, the glow of the magic circle intensifies. Then, a green object begins to rise from the center of the circle.

Once the object reaches a height of about fifty centimeters, it stops. Simultaneously, the magic circle loses its luster and dissolves away into nothingness.

What remains is a green, humanoid entity. Anyone familiar with light novels or games would probably name it a Goblin.

"It's a success. For my current objective, a summoning magic of at least this caliber is necessary."

Summoning magic.

It is a form of magic used to call forth and employ beings from outside this world. With higher-level spells, you can summon some seriously dangerous entities, but naturally, I haven't mastered magic of that level yet.

To be blunt, the Lesser Demon I summoned this time is a low-level creature. It seems completely useless for combat, but it possesses another ability that I can exploit.

As a characteristic, it is invisible to humans who haven't trained their mana. Furthermore, it is fundamentally like a spiritual entity and does not possess a materialized physical body.

Thanks to that, it can easily phase through walls, and by consuming mana, it can temporarily materialize its body. Additionally, it can communicate with me, its summoner, via a telepathy-like link, allowing me to grasp its current location.

"Hey, can you hear me?"

[I can hear you, Master.]

"...Ngh... alright. First, follow me."

[Understood.]

Though slightly bewildered by the words reaching my brain directly rather than as spoken audio, I leave the house. First, I want to confirm if the telepathy works and whether other people can see it.

(Lesser Demon, follow right behind me.)

[Understood.]

After confirming that the Lesser Demon is following my instructions, I head toward the nearest station. My destination is the city where I went on a date with Kojina-san.

+++

While heading to our destination by train, I keep my gaze lowered from where I am sitting. The Lesser Demon is positioned right there, overlapping with the legs of a man standing in front of me.

Reconfirming that it is invisible to others and doesn't have a physical form, the train begins to decelerate and arrives at the target station. When I stand up from my seat and walk toward the doors, the Lesser Demon follows behind me with a bouncy, shuffling gait.

The reason I came here today is to find that woman in traditional Japanese clothing whom I encountered during last week's date. After that, I plan to have the Lesser Demon stalk her to find out where she lives.

I wander around searching, matching the location and time. I am having a hard time finding her, so while taking a break, I buy a drink from a vending machine to quench my thirst.

Just then, the woman in question—wearing a different set of traditional Japanese clothing than last week—is walking on the opposite side of the street. Hurriedly gulping down my drink, I toss the empty can into the trash bin and pursue her so as not to lose sight of her.

Once I close the distance to about five meters behind her, I give the Lesser Demon an order.

(Lesser Demon, stalk that woman.)

[Understood.]

The Lesser Demon picks up its pace and moves right behind her. Unaware that she is being stalked, the woman will surely guide us straight to her home.

(Follow her just like that, and wait at the house where she goes to sleep.)

[Understood.]

With this, her home address should be revealed. Today's plan ends in success, and I head home chuckling inwardly.

+++

And then comes the next day, Monday. Even though we've started dating, my relationship with Kojina-san hasn't particularly changed in the classroom, and no one has found out.

Since Ichikawa-senpai seems like a hassle, I haven't been showing my face at the Fortune-Telling Club either. Occasionally, our eyes lock, and we simply enjoy our secret relationship.

After school, since the second-term final exams are next week, we aren't going on any dates. Though, as a token arrangement, we've promised to study together somewhere this Saturday.

Once classes end and after-school hours begin, I rush to the station. My destination is the place where the Lesser Demon is currently located.

+++

That house is located at a distance that wouldn't be an issue even on foot from that station. It is an upscale residential area where even an ordinary high schooler like me can tell at a glance that the land value is astronomical.

"Whoa... this is a mansion..."

As I retrieve the Lesser Demon, the words naturally escape my mouth while looking at the woman's house. Surrounded by a grand wall, it's clear at this point that the property is worth hundreds of millions of yen.

"The security looks tight here too."

It's highly likely that I need to act cautiously. Thinking that I should first gather information from the Lesser Demon, I decide to head home quickly for today.

+++

This week, I enjoyed myself once each with Iroha and Chihiro in the sex room during the weekdays. And on Saturday, it's a test-study date with Kojina-san.

As a result of discussing where to do it, it was surprisingly decided to be her room. This is apparently because she cares about the gazes of others at places like the library.

If it were at my house, I would have to walk Kojina-san back to her home afterward, and she seems to feel bad about putting that burden on me. So, the remaining option was Kojina-san's house.

On that day, being invited to my girlfriend's house for the first time, I naturally head there feeling nervous. Along the way, I buy several types of cakes at a popular pastry shop as a souvenir and arrive at the destination in the morning.

Because I contacted her in advance, Kojina-san comes out to greet me in front of the house.

"Good morning, Saida-kun."

"Kojina-san, good morning."

"Only my mother is home today; my father and brother are out, so please relax."

"...I guess I'm less nervous than I would be if your dad were here."

As far as I can see from the outside, her house is a two-story building of a decent size. Since it's a family of four—the parents and her younger brother—it should be plenty spacious.

"Excuse me for intruding."

"Yes, come on in."

"Oh, here, a souvenir."

"Ah, thank you. You didn't have to worry about that."

"No, no."

We converse as I am invited inside the house. Following behind Kojina-san, I am led to her mother who is in the living room.

"Excuse me for intruding. I'm Saida."

"Welcome. It's been since the sports festival, hasn't it?"

"Yes."

"Mom, this is from Saida-kun."

"Oh, my. Thank you. Let's have it during break time."

"Well then, we're going to my room. Shall we go?"

"Roger. ...Excuse me, then."

"Yes. Good luck with your studies."

Leaving the living room, Kojina-san goes upstairs to the second floor. Following her, we reach the second floor, and she gives me an explanation.

"This is the restroom, so feel free to use it without hesitation."

"G-Got it."

"This side is my brother's room, and here is my room. Well then, please come in."

While thinking to myself that sharing a restroom with Kojina-san is somehow arousing, I finally infiltrate her room. The room is a girlish space dominated by the color pink, and it carries a sweet fragrance entirely different from the rooms of the crest-slaves I've entered before.

"...It's the first time... a boy has ever entered my room..."

"...What about your brother?"

"My brother is a separate category."

While Kojina-san flashes a wry smile, I am prompted to sit on the cushions placed around the table. The positional relationship is that she sits toward the door, and I sit directly facing opposite her.

"Phew... Shall we chat a little bit first?"

"Y-Yeah, let's do that."

"Well then, I'll go prepare some drinks. Is hot coffee alright?"

"Yeah, thank you."

"Okay. Please wait a moment~♪"

Saying it playfully, Kojina-san leaves the room. Leaving a high school boy alone in a high school girl's bedroom implies she trusts me quite a bit.

"No, is it... love?"

If it's a lover, one might think it can't be helped even if they succumb to temptation. That being said, I won't go rummaging through the high chest in her room here.

In particular, checking the inside of the small drawers where underwear is likely stored is out of the question. Naturally, I won't plunge my face into her bed to breathe in a chestful of her sweet scent either.

"............My thoughts are purely those of a pervert."

Eventually, I intend for us to be in a relationship where we entwine naked on top of this bed, but now is not the time. For a while, I'll enjoy a sweet, innocent couple's relationship.

After all, I already have partners like Iroha and Chihiro with whom I can regularly mate to relieve my accumulated sexual desire.
