I Got Caught Up in a Hero Summon, but the Other World was at Peace!

From the introduction: [???]: Well, well, what do we have here? ‘Jumper’ was it? Your Benefactor told us to take care of the introductions this time over. Nice to meet ya~~ [!!!]: Why are you so relaxed?! The fact that there’s someone even more outrageous than Shallow Vernal is already shocking enough! I can’t even imagine how some people would react if they knew this… [???]: Well, nothing we can do about it anyway. So, Jumper, first of all this mysterious transcendental beauty here and the waste of space over there are called [???] and [!!!]. We may look like the Phantasmal King and the God of Disasters or certain afterword due, but there’s no actual relation between us. We were kinda made to be your guides… [!!!]: Rather than giving some weird introductions, shouldn’t we be explaining about the world and circumstances? – Jumper, listen well. This world is called Trinia and it’s divided into three realms, one for the Gods, one for the Humans, and one for the Demons. It was created by Shallow Vernal-sama thousands of years ago- [???]: I was just about to talk about that, you idiot! Indeed, much like there are three realms, the beings in this world can be roughly categorized in those same three divisions. Although, strictly speaking, there are many, many races, species, and types of beings in these lands [!!!]: Each realm has their own leaders. The Human countries have their Kings and Emperors depending on each country. The Demon Realm is likewise controlled by the Six Kings who are the strongest demons around. While the God Realm is led by the Three Supreme Gods and the being that stands above all, Shallow Vernal. [???]: Shallow Vernal doesn’t do much actual leading though. You can also see their strong cultural differences in each realm, with Human changing titles, passing down them to blood relatives and such. The Demons meanwhile value strength and the Gods are real fans of sticking to the hierarchy and positions. [!!!]: For a long time, these realms didn’t interact with each other. While 20000 years ago the Demons led by Kuromueina did invade the God Realm for personal reasons, as a whole they kept to each other. The Human realm, after being created, was also unaware of the Demon Realm at large. [???]: That changed nearly a thousand years ago because of some weakling that mistook the feelings of her adoptive mother. Taking the underserved name of ‘Demon Lord’, the dumb kid ended up invading the Human Realm. Well, even if she wasn’t that strong by Demon standards, she was still overwhelmingly powerful when compared to humans. [!!!]: At the time the humans used the ‘summoning circle’ magic to summon an individual from another world. That girl, Hikari, would end up becoming the Hero that, alongside her friends, defeated the Demon Lord and her army, and then spent years establishing peace between the humans, as well as with the other Realms… Umu. That was a serious development I can approve of! [???]: The actual journey and Hero were a lot sillier than you may think by just hearing that. [!!!]: Still, in her name and deeds, the Human Realm created a tradition in which they would summon another person from the same world as the first hero to aid them in the festival every ten years. It’s a big event to remember why the Three Realms are friends [???]: The world is really at peace to bother with such things… Not like the first hero was the only one pushing for peace at the time, and many have worked tirelessly to keep the balance you see nowadays. [!!!]: Regardless, it's a great responsibility to take care of it. This time over, in a few days, the summoning ceremony is to be conducted by Lilia Albert from the Kingdom of Symphonia… [???]: If things go on as they are right now, then there will be certain problems with it. Namely, the fact that there will be some extras summoned alongside the teen that plays the role of hero. [!!!]: For some reason, you got some say on choosing how things will play out. We will be keep explaining you things as we go on [???] Yeah, yeah. Also have this already, Jumper. We don’t have all day.
