Whether you're interested in the political power struggle of Estel princes and Sis Diana or not, or whether you're interested in the old and new religion debate or not, there's no denying, that the beginning of devil invasion six years ago is something that have changed the world

Traveling between countries have become more dangerous. The supposedly safe main road at the centre of the dungeon is no longer safe as there are countless cases of devil coming out from portal and wreck havoc there. Some monsters, whether they're an F class monster to an S rank monster are equally effected as well. Some getting slaughter by the devil, while other being tamed or being made into a devil itself

The ten heroes and their fellow companions have been working hard, trying their best to stop the crisis, as the special blessing of the ten heroes made it easier for the heroes themselves, as well as their allies to gain the upper hand during a battle with the devil

All, all of these can be trace back six years ago. There are countless tales of the version, but most prevailing one is the one from the church of old teaching, and the one told by Estel and New teaching

Let start with the old follower version of the story. One day, a fault saint from the new religion suddenly visited them at the holy palace, all by "himself", or so they're lead to be believe as the saint had a reputation of traveling all alone. The saint arrival and the disappearance of the Prince of Holy Palace at that time was no mere coincidence, and as such, they took the saint to the castle in order to investigate the truth, and that's when the saint, along with the infamous behemoth slayer at that time performed an unknown ritual to summon the fallen god into this world, and thus, marking the beginning of devil invasion. Both the faulty saint as well as the behemoth slayer lost their life, as the first fault devil they summoned was a giant, a giant towering even other giant, said to be as large as the Holy Palace itself. The giant almost destroy the entirety of the country when the courageous Saintess Angela put her life on the line to stop the giant, she survived, at the cost of being turned into a Penanggal, a cost she gladly accepted in order to raise the banner to fight the fallen god.

And now, onto the Princess Diana and Saintess Rumia version of the story. As the ten heroes are all living inside of Estel, and the various plot of the old follower to kidnapping them, Saint Louis alongside the behemoth slayer went to the Holy Palace in order to negotiate with them, and that's when an unfair treatment to the saint begin as Saint Louis was being put under a restraint inside the holy palace. The saint, alongside the behemoth slayer then found out a ploy from the holy palace. They send the Holy Palace prince and his convoys to kidnap the ten heroes, conspiring with the believer of the fallen god. Thus, the two heroes bravely put their life on the line to stop the ploy, and Saintess Angela, sensing she was about to be defeated, unleash the giant to beat those two, only to backfire, causing destruction toward the holy palace

As the students analyze the story, they found similarity between the two. Both version indeed admitting that the incident started at the holy palace, with the four role involving Saint Louis, Saintess Angela, the behemoth slayer and the giant as the key figures in the story, and both story ended up with the death of two of the key figures, as well as the destruction of the country

And interestingly, both version are woven with both the truth and lies, so much so that only those who were directly involved know the truth behind what happen six years ago. Princess Diana, Saintess Angela and Rumia, Sis Qis, Principal Alice and Rean seems to be knowing the truth, but I guess each keeping it a secret, each for their own reason

"Is it true that a demon will be the one replacing Saint Louis soon?" 

"It's to early too said that. I can ask Saintess Rumia if you like" [Charlotte]

And another thing, Saint Louis was officially declared death by all, even by the new religion, by his own request. Those who knew he is still alive dubbed him the traveling saint, as he alongside Seraph, the fallen angel king travel across Achalasia in order to investigate the dark guild, the two traitorous princes of demon kingdom and their connection with the fallen god. He will occasionally use the Goddess orb found through the Achalasia, as well as the one inside a church to communicate with Saintess Rumia in order to relay any information to us. Apparently, he awaken the same ability as Saintess Rumia does, albeit only a small portion of it

"That's all for today? Do you have any questions?" [Charlotte]

"Teacher, how did other countries without heroes fare? The heroes only helps Estel, Kiserre, Malsia, Beast Kingdom, Demon kingdom and the headquarters of new religion. Isn't it a bit unfair?"

"True. We mostly help those countries because they're the one that have been protecting and supporting us for the past six years. As for the other countries, even though there have been an attempt to kidnap us in the past by their royalty, we will still lend them our support, just that they aren't as friendly as the aforementioned countries. Calling us the princess dog etc. Plus, when one of our owns help them, they had the nerve to block out the exit, just so they can have the heroes all by themselves" [Charlotte]

"That seriously happen..."

"Yup" [Charlotte]

Well, that all happen in the past, and should I go to that country once more and they did the same thing, I will just storm their castle. The only one stopping me from doing it the last time was the adventures accompanying me and the Estel's embassy there
