Nino: Listen attentively to the story.

Aria: Monsters and humans used to live without a divide between them.
Aria: The two worlds naturally overlapped, and you could freely move from one to the other.
Aria: Monsters and humans were on seemingly good terms.
Aria: But they did not truly accept one another beneath the surface.
Aria: Because of that, it was frowned upon to surround yourself with monsters if you're a human, and vice versa.
Aria: But it wasn't exactly disallowed, so many monsters and humans adapted to this lifestyle.
Aria: My family was one of these, we settled in a humble small village around here long ago!
Nino: Oh, really?
Nino: How was the life there? Wouldn't you have had a hard time because of the other monsters?
Nino: Also this tea is kind of bland, sorry.
Nino: ...Not that I don't like it, of course, haha--
Aria: Oh shush, I just ran out of sugar! It'll taste better with the muffins!
Nino: Fine whatever you say.
Nino: ...Oh uh! Sorry for interrupting, please continue!
Aria: It's alright! As long as you're listening!
Aria: So anyway...
Aria: It was a comfortable life in a quiet place, away from the never ending political disagreements between monsters and humans at that time.
Aria: Although, like you said, it was indeed hard to be a human in a majorly monster populated area.
Aria: I never had any friends just because I was human, and sometimes the rest of the monster kids shunned me...
Aria: But I wasn't lonely! I had my family with me.

Nino: Was the war mostly fought physically, with soldiers? Or was magic involved? Who started it? How did it end? What was the goal?

Aria: Well, I guess I wasn't lonely until after the war.
Aria: That was when the divide between the two worlds came to be.
Aria: The divide ended the war, because it made moving from one world to the other impossible to achieve.
Aria: Not only that, but it trapped everyone inside with a strong dome barrier.
Aria: I'm sure you know what the dome is, right?
Nino: Of course I do!! It's the layer covering the sky!
Nino: I wouldn't forget what I see every day, you know!
Aria: O-okay sorry, I'm just making sure!
Nino: Well, just keep going. I'm listening.
Nino: Actually, wait, I have some questions...
Nino: Was the war physically fought? Was there magic?
Aria: Of course it was physically fought, with soldiers from both sides...
Aria: But, uh...
Aria: Magic?
Aria: Nino, you big goof.
Aria: Magic isn't real!
Nino: Hey don't make fun of me!
Nino: I'm just, uhh, refreshing my memory. Yeah! Totally.
Aria: Suuure, sure.
Nino: Something tells me you don't believe that.
Aria: You're just too silly sometimes.
Nino: >:[
Nino: Well, I have more questions.
Nino: Who started the war, and why?
Aria: Nino, I don't know everything!
Aria: I'm sure the web of political disagreements between monsters and humans is something far too daunting for me to try and figure out!
Nino: Fiiine okay, that's fair I guess.
Aria: So, moving on...

Aria: Because of the death of the previous prince in the war, and this world nearly dying as a result of it...
Aria: Everyone was trapped, and everything was left in shambles.
Aria: Until the new prince rebuilt it all.
Aria: And then, he made a promise to everyone inhabiting the new world.
Aria: "You will not be harmed again", were his exact words.
Aria: He did not allow humans to be in this world anymore.
Aria: And this new rule is what defined this world's history.

Nino: ...
Nino: I'm really sorry to hear that, it must've been awful.
Aria: It's fine, please don't be sorry!
Nino: I really don't like seeing you sad like that, I-I guess.
Nino: Sorry if that's a weird thing to say.
Nino: Your face is the face of someone who should only be smiling.
Nino: Okay THAT was definitely weird, I'm sorr-
Aria: Nino, stop apologizing oh my gosh.
Aria: I'm not sad, it's just because I'm remembering tough times!
Aria: But it's alright now, I promise.
Aria: Because I'm not lonely anymore!
Aria: I have Kotori, and now you and Five...
Aria: So don't worry about it at all!
Nino: Well if you say so... But are you sure it's really fine?
Aria: Yup!
Aria: I would hate to make people worry about me, so please don't worry anymore.
Aria: ...I guess I darkened the mood a little, ehehe...
Nino: No no, it's fine! I was the one who asked, it's not your fault.
Aria: Well, let's try and change the subject!
Aria: Do you have anything else you want to ask about?
