I have acquired super powers in another world, but I am still invincible in the real world

Frankly speaking, the things in my house that are inconvenient for outsiders to see, at best, are the door to another world... It shouldn't matter.

"That's it. Let's start preparing for the exam tomorrow!"

──After deciding to have a book club at my house tomorrow, Kaori and I said goodbye to each other and went home.

***

"──Ah, this formula should be used here."

"This, that's it..."

the next day.

After Kaori came to my house according to the appointment, we immediately sat down to read.

As Kaori said yesterday, the two subjects of classical literature and English are her weaknesses.On the other hand, she is very good at instructing others in mathematics in an easy-to-understand way, which has benefited me a lot.It seems that there should be no need to worry about this exam.

"As expected of Kaori...Thank you for helping me fill the big hole in mathematics."

"No, you're welcome! I just want to thank Yuya-san... Your classical literature and English are very good, aren't you!"

"Horse, so-so."

Sorry, this is because I have the blessing of the skill [Language Understanding]...

"Aww?"

"Puff."

When I thought so ashamedly, Nate and Akatzky both tilted their heads to look at me.Speaking of this, I can vaguely understand what they want to express, and it is also a credit to this skill.

──Kaori and I taught each other weak subjects like this, and the study session went very smoothly.

Ms. Rexia and Luna have visited my home in another world before, but this is the first time a girl has visited my home in the real world, so I was a little nervous at first.However, thanks to the company of Knight and Akazki, the mood is much more stable now.

After reading for a long time, we decided to take a short break.Kaori stretched her waist and patted Nate who was staying nearby.

"Hmm... Speaking of which... I've seen Knight before. I didn't expect that your family has a new member named Akatzky."

"Yeah, it just came to our house recently."

"I see... Please give me your advice, Akatzky."

"Puff ~"

While accepting Kaori's touch, Akatzky raised one of his feet and greeted Kaori casually.

"Ah, sorry...can I borrow the bathroom?"

"Huh? Ah, please."

Kaori asked this question with some embarrassment, and got my permission to leave the room.

We read in a room with tatami mats.This room is usually a vacant room, so it can come in handy at this time.This room is quite spacious. In fact, after deducting my living space, there are still many rooms that are unused.

When Knight, Akazki, and I were waiting for Kaori to come back, something suddenly occurred to me.

"Ah! I forgot to tell Kaori where the toilet is!"

I hurriedly rushed out of the room to look for Kaori, and inadvertently saw where the [Gate to Another World] was located.

The door is hidden in the secret room whose wall was broken by me.I didn't repair the walls after I damaged them, so people who saw them for the first time might be curious and go in to find out.

I screamed in my heart that something was wrong, so I went in to have a look──

"Yuya-san...? This is...?"

──I saw Kaori standing in front of the [Gate to Another World] with a blank face.

And she had already opened that door, and the world on the opposite side—that is, a room in another world appeared before her eyes.

"Ah...uh...that..."

I didn't expect that Kaori would discover the door to another world, and I was speechless for a while.

Jiazhi soon realized that her behavior was too reckless, and her expression was filled with guilt.

"Ah!...Sorry. I couldn't find the bathroom, so I stumbled upon this room... I always felt like something was calling me, and when I walked in, I saw this door..."

"Uh……"

It doesn't matter just walking into this room, the problem is that Kaori opened the [Gate to Another World] placed here.

However, due to the effect of [Gate to Another World], she cannot just walk into another world.In other words, she should have experienced the extraordinary situation of being unable to walk in even though she opened the door.

I hesitated for a long time... finally decided to tell the truth.

Firstly, this is not a bad thing, and secondly, I think it is more difficult for me to come up with a lie that can successfully shift the focus under this situation.

With some hesitation, I told Kaori the truth.

"Well...you might not believe it...in fact, this door is connected to other worlds."

"Is, other world...?"

"Look..."

After I walked through that door as a demonstration, Kaori's eyes widened even further.

"After I opened the door just now, I was also taken aback by the scenery behind the door... But I wanted to enter the room behind the door, but was blocked from the door..."

"Sorry, it seems like only people with my permission can enter this door."

"Yes, that's right..."

Kaori let out a voice, dumbfounded.

"By the way...you mentioned other worlds, what do you mean...?"

"It literally means another world different from the earth."

"Different from Earth?"

"Yes. For example, there is magic in another world, and I can use it now."

"magic?"

After Kaori was frightened by the scene in front of her, she still hadn't calmed down, so I continued to create a ball of water on my palm.
