( Yuuki's POV )
When I entered the royal library I was surprised by the amount of material that was available, The Babylon library was bigger but this would be a nice addition to our collection.
I opened a small portal in front of me and out of there came a spherical drone, that thing was going to scan all the contents of the library and create copies for our library, Leen was going to help me learn the history of this world.
While that drone was doing its thing, I picked up some books that interested me: magic stone usage theory, magic engraving, and an encyclopedia of ancient artifacts.
I was alone in the library so I immersed myself in my reading and what caught my attention the most was the book on using magic stones.
Magic stones were basically the hearts of monsters, these could be used for a wide variety of things, from lights that illuminated cities to powerful magical weapons, adventurers made a living out of collecting these magical stones.
Magic weapons were nothing I could already create better things from so I was more interested in everyday objects that improved people's quality of life but the information was scarce in these books, I guess I would have to visit a regular bookstore to learn more about it.
I got up to look for more books and that's when I noticed a blond head peeking out from the other side of the table I was using, that was Princess Maribelle.
Yuuki: Hey little girl, can I help you with something?
Maribelle: Onii-chan, are you a hero?
Yuuki: wrong guy, you're looking for someone named Kouki.
Maribelle: My sister said that those who came to the castle are heroes who are going to save our kingdom, are you someone strong?
Yuuki: Well, I don't want to brag, but I'd say I'm decently strong, like I could throw a car over a house?
Maribelle: Oooh, what's a car?
Yuuki: That is a vehicle of my world, that people use to move around.
Maribelle: oooh Tell me more about your world, Onii-chan!
Yuuki: Sure~
I set aside my reading time to entertain the little princess with stories of the world we came from and also threw in stories from the worlds I had visited, she was delighted to hear my stories, so I couldn't help myself.
???: Mari! Are you here?
Maribelle: Oh sister, here here, I'm talking to one of the heroes!
We heard a voice come in and it turned out to be the first princess Liliana S.B., and she came over to where we were upon hearing her sister's voice.
Liliana S.B.: That's not right, you shouldn't bother our honorable gues-
The princess was worried that her sister would be bothering me but when she saw me her words were cut off and she stared at me but now she recovered faster than the other times.
Liliana: G-good morning to you, Mr. Hero, I hope my sister isn't bothering you.
Yuuki: Not at all, princess, I enjoyed the company, and please just call me Yuuki, I don't feel good with too many formalities.
Liliana: I-I see, then that's what I'll do.
Maribelle: Onii-chan was telling me about the technology of his world.
Liliana: I see. Would you mind if I listen too?
Yuuki: That's fine by me, but could I ask you a favor, princess?
Liliana: Of course, if it is within my capabilities I will provide any help I can.
Yuuki: I need a guide, There's something I'd like to find in the city.
Liliana: What's that?
Yuuki: I'm looking for a book.
Liliana: A book? It's something you can't find in our library, Is that a special book?
Yuuki: No, it's something common, something a normal person would read.
Liliana: I see, then I'll arrange for a guide to be ready for you tomorrow.
Yuuki: I appreciate that.
I spent some more time in the bookstore talking to the princesses before returning to my room, there I opened some portals and the rest of my group entered the place, it was time to talk about our situation.
Yuuki: Well, what do you think about giving our help to this kingdom?
Tsukiumi: I have no problem whit that, there doesn't seem to be anything strange with the knights and servants, they were treating us appropriately for what they are asking of us.
Yuuki: Yumina, did you see someone untrustworthy?
Yumina: A few, those who had the most dishonest nature were the king, the Pope and some members of the church.
Yuuki: Yes, I don't trust that Pope at all, but it's good to know that not all of the Church is dangerous, The King is under the thumb of the Pope and he seems to be completely fine with that, but the rest of the royal family seems really worried about the future of this kingdom.
Yumina: You mean the princess, you two seemed very close in the library~
Yuuki: I was just gathering information.
The princess was quite mature for her age so I was able to get a good idea of the state of this kingdom from our conversation.
Yumina: Well it's not like I don't understand how she must be feeling, I've been in her situation before with a hero appearing to save her kingdom.
Yuuki: I'm not even the one with the hero class.
Yumina: I guess that Kouki kid has some potential but he's too green, I think he'll crack at the moment of truth.
A correct assessment from Yumina, as expected.
Yuuki: Well, then it's decided, we will support this kingdom for the time being while we monitor the movements of the church, any objections?
The others did not object, I ended the meeting, and the girls returned to their rooms.
The next day more training awaited us in the morning but something interesting also happened, today we were going to do some practice battles and I had to go against the hero Kouki, the truth is there was another person I would like to face but this will be interesting.
