Fourteen students of sixteen years of age could be seen sitting in a classroom while a man in his early forties was slumped over his desk at the front of the room.

If one were to stand too close to this 'teacher', they would realise that he reeked of alcohol and was currently sleeping off a hangover from the night before. This was not unusual as most days he was either asleep during class to begin with, or he took a nap after drinking 'coffee' from his flask. This was Mr. Davis, but most of the students referred to him as Brandon. He had long shaggy hair that reached his shoulders and an unkempt beard.

The students were grouped into a few cliques.

The popular kids, which consisted of three attractive young men, one blonde and two brunette. They all had bodies akin to that of athletes, which makes sense considering that is exactly what they were. The two brunettes were twins, and both stood at five foot eight and the blonde was five foot nine. There were also two beautiful girls with them, one redhead and one with black hair. Both also had toned bodies, but the black-haired girl was slightly more well developed. The redhead was five foot five and the black-haired girl was five foot six.

These five were Lachlan, Anton and Samuel (the twins), Alexis, and Yuki.

The next group consisted of the nerdy kids, all three of which were males with brownish-blonde hair. Two of them were moderately thin with almost no muscle and the other was slightly overweight. None of them were particularly attractive, but they weren't massively ugly either. The two thin boys were five foot seven, and the overweight one was five foot ten.

These three were Edmund, Codie, and Harry.

In the back right hand corner was a group that were all clearly high out of their minds. It wasn't exactly a secret as they were passing a joint between them without a care in the world. Two of them were guys, one had blonde hair and the other had black hair and both were five foot eight. They were pretty-good looking despite having appearances that would suggest they put absolutely no effort in whatsoever. The other three were girls who were fairly attractive with two of them being blonde and one of them being brunette. The blondes were five foot six and the brunette was five foot three.

these five were Flint, Cedric, Alva, Isabella, and Svetlana.

The fifteenth and final student had only just entered the room and sat down despite the lesson, if it could even be called that, having started over thirty minutes ago. This was Cadmus, he sat alone without any contact with the other students. Some people could infer from this that Cadmus was being bullied, but those people would be wrong. Cadmus being avoided did not originate from him being ridiculed or bullied, but from pure fear. While this may be confusing to those who had never seen him at first as soon as they found out that Cadmus stood at an astonishing height of seven foot eleven it all made sense.

For most people, this height would lead to medical difficulties due to their bones and muscles being unable to support the person in question. However, Cadmus had both incredibly dense muscles and bones which allowed his body to both support itself normally and surpass a regular human physique. His body had an abnormal growth rate that led to both his massive height and incredibly muscular and powerful body when compared to other humans (think Jack Hanma's body after his second height operation but natural).

He had short blonde hair with piercing blue eyes and a quite attractive face. Despite this, it was no surprise that absolutely nobody dared to mess with Cadmus, or even interact with him as they feared for their own safety. Cadmus, however, was not a bad person at all. In fact, he wanted to be friends with people and live a normal life.

However, he had spent the majority of his life alone and believed it would most likely stay that way.

While the entire room continued what they were doing, nobody noticed that spanning across the entire floor was a large circle covered in runic symbols that had a faint glow to it. After about ten more seconds, the glow had increased to be so bright that nobody could ignore it purposely or accidentally which startled the students. Mr. Davis was still asleep despite the now worried students, no surprise there as he did not wake up for much when he was hungover.

Before anyone could attempt to leave the room, everyone present disappeared in an instant. It happened so quickly that it took the students a moment to realise they were no longer in their classroom, but instead a large throne room.

Before any of them could even make a noise, a loud voice alerted them all to the location of the man who seemed to be a King, "Welcome Heroes, I am King Ludwig Klyntos of the great Kingdom of Klyntos. You may be confused about where you currently are, so I will explain what is happening to you all. This world is called Terra, and throughout history it has been inhabited by Humans, Monsters and Demons."

There was some whispering between the students about what was going on, but after realising the King had stopped talking they became silent.

The King started speaking again, "However, unlike Humans, the Monsters are savage beasts that are commanded by the Demons who want to overthrow the Humans and take the surface for their own after being locked in the twelve dungeons created by Humanities first Heroes. The reason they were sealed started thousands of years ago. The Demons and Monsters became too violent and unstable for the Humans to be able to have a peaceful world coexisting with them. This meant we had to use an ancient ritual to summon Heroes from another world who possessed great power.

These Heroes created twelve dungeons, eight of these were made to contain the Demon Generals: Astaroth, Maggot, Asmodee, Beelzebub, Oriens, Paimon, Ariton and Amaymon. All eight Generals possess power unimaginable to most, but they were not the worst threat. The remaining four dungeons were made to contain the four Demon Princes: Lucifer, Leviathan, Satan, and Belial. These enemies were so powerful, without the help of summoned Heroes it would have been impossible to defeat them.

The regular monsters were also sealed in these dungeons, with them being spread between them all. The lower into a dungeon you go, the more powerful the monsters become, with our twelve greatest enemies lying in the darkest depths. By hunting these monsters, people can gain great strength for themselves."

Cutting off the King, Lachlan butted in, "If the twelve strongest guys are dead then what do you need us for?"

Looking slightly annoyed, the King replied, "I was just about to get onto that. To answer your question, the eight Demon Generals and four Demon Princes have been revived and you are our new Heroes.

Now, back to what I was saying before, by hunting monsters, people can strengthen their Blessings. A Blessing is the power or ability granted at birth. While everyone in this world has a blessing, not all of them are useful in combat or even at all. The majority of Blessings can also not be upgraded from their original ranks. All fifteen summoned Heroes have upgradeable Blessings, and they are all bound to be powerful.

Along with Blessings, everyone has a Talent that will change something about them, normally for the better. Nobody can upgrade their Talents, but Heroes regularly have very powerful Talents, so none of you should be worried."

Harry now asked a question, "What do you mean by ranks?" While he was fairly sure he knew what it meant due to his countless hours playing games, he had to make sure.

The King responded, "That is a good question, the ranks for blessings and talents go like this: F, E, D, C, B, A, S, SS, SSS. F is the lowest, and SSS is the highest. Now I believe it is time for you fifteen Heroes to have your Blessings and Talents checked. One at a time, come and place your hand on this crystal ball to get checked."

None of the students dared to disagree, and one by one decided to touch the crystal ball.
