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

I've only been fighting monsters so far, so meeting humans in a different world is a novelty.Although when I learned that there was a sage, I knew that this was a world with humans...

Unfortunately, the process of meeting people from another world for the first time was not smooth.I saved the girl in the dress when she was attacked by a monster, and then I just left.I always thought that unless I voluntarily left this forest full of monsters, I would never see her again.

However, at this very moment, I saved the same girl from a monster────

***

"────Please marry me!"

"………………What did you say?"

The girl in the fancy gown uttered it right away, and I really didn't know how to respond.

...What nonsense is this girl talking about?

I wondered, thinking that I had heard it wrong, when the middle-aged knight hurried towards the girl.

"Lei, Princess Lexia!? What are you doing!"

"What... of course is a marriage proposal."

"I can see that you are proposing! I mean, why did you say such a thing suddenly! Do you have the self-consciousness of being a princess!? Besides, you don't even know each other...!"

"It was love at first sight! Do you have an opinion!?"

"Are you getting angry from embarrassment!?"

...Uh, what play is this in?

The conversation in front of me was like a cross talk, I couldn't help being startled, and looked around. "Ah, it's started again." The other soldiers shrugged helplessly with this thought.Well, is this kind of thing normal?Really, really hard...

I couldn't help thinking this way, and looked at the middle-aged knight and the girl.The middle-aged knight noticed my gaze and coughed lightly twice.

"Ahem! Sorry, I made you laugh. If possible, can we go to a safer place to talk and introduce each other's identities..."

"I'm Rexia von Alseria! By the way, what's your name!?"

"...Princess Rexia, didn't you hear me say that I want to talk to a safe place?"

"I just heard it, so I decided to do it."

"I can't stand it..."

Hearing the girl's justification, the middle-aged knight couldn't help but put his hand on his forehead, looking up at the sky and sighing.

"Uh... If you don't mind, would you like to come to my house...?"

I proposed this, on the one hand, out of sympathy for the middle-aged knight, and when it comes to a safe place, I only want my house.

... The other party does not know whether it is an enemy or a friend, and it is very dangerous to invite such a person into the house.However, they struggled even against high-ranking goblins, so even if they did use force, I wouldn't be unable to handle it.

In the worst case, I can escape back to Earth, and I'm the only one who can go through that door anyway.

... However, I really don't think these people are bad people.Although this is just my intuitive judgment, there is no basis at all.

When the soldiers heard my proposal, they panicked beyond imagination.

"Home, home!? Are you in this [Great Demon Realm]!?"

"That's right...he really lives here..."

"Who the hell is he...?"

The middle-aged knight was as surprised as the soldiers, but he immediately nodded in agreement with the suggestion.

"That's the best, thank you."

"Are you going to your boyfriend's house so soon!? I-I'm not ready yet...!"

"Princess Lexia, please stop talking..."

The middle-aged knight sighed and seemed quite tired.

***

"There is really a house..."

"...Only here is a completely different space, right?"

"How can there be such a leisurely place in [Great Demon Realm]..."

The soldier entered the home...to be precise, the safe area around the house, and looked around with astonishment written all over his face.

Although they were brought to my house, there was not enough room for everyone inside, so only the middle-aged knight and the girl entered the house, while the others waited outside.

We sat down to rest in the chairs, and then the middle-aged knight spoke first.

"Please allow me to formally introduce myself first. My name is Owen, and I am a knight serving Princess Lexia in the Kingdom of Alseria. Thank you for saving Princess Lexia... No, you saved us all, really. Grateful."

"Please, please hold your head up! I just happened to be passing there!"

The other party suddenly bowed his head to thank me, and I hurriedly asked him not to do so, but the middle-aged knight...Mr. Owen did not raise his head for a long time.

"...No, even if we passed by by chance, this place is the [Great Demon Realm]. It is a miracle that we were rescued safely after entering such a dangerous area. So, please accept my thanks."

"I-I see..."

Since the other party said this, I can only accept it.

And more importantly, although he just mentioned it casually, even in the eyes of people from other worlds, this place is indeed a dangerous place...

When I couldn't help but look stiff, the girl also officially reported her name.

"I am Rexia von Alseria, the eldest princess of the Alseria Kingdom, thank you for saving me!"

"No, you're welcome, as long as you're fine... huh? Princess?"

Thinking stopped immediately.

...So, before returning here, when Mr. Owen was arguing with the girl... Miss Lexia, Mr. Owen did mention the word princess...

…………

"...Excuse me, Mr. Owen."

"What's up?"

"That... Miss Rexia is... a princess...?"
