Somewhere on Earth, there was a group of people standing in front of the large orange portal. A tunnel. There were lots of military people as well as the researchers standing and analyzing it.

“Hey, don’t stand that close to a tunnel, you might get sucked in.” said one researcher to another.

“I-i-i am s-sorry” replied the other, who was standing very close to the tunnel. “this is my first day, I do not know many details”

“A rookie, huh? Well just look at the screen and make sure to tell me any energy outburst there is to happen”

“Yes sir” the very young boy with glasses replied “Sir, may I ask?”

“Huh? Sure go ahead” answered the other researcher. He looked like he was in his fifties and had black hair with some gray strands.

“Ho-horrors aren’t gonna come out, right?”

“They should not," replied the older researcher with a very calm voice.

“What do you mean, should not? There is a possibility?”

“Well, there is always a possibility. But don’t really stress out. We sent a group of B tier hunters. The “Lullaby”. Weird name, I must say. I think it was related to their leader's ability.”

“B tier means they are strong right?”

“Boy, where did you come from? Don’t they teach it at schools? Do you at least know the horrors?”

“The n-names only. I am sorry sir! I was transferred from a geological department. All this is new for me!” said the boy, almost crying.

“Fine, listen now.” replied the older one “This tunnel is emitting a very strong energy output. Twe gave it the level - Saturn. That means that it was most likely to contain horrors with the Saturn level of powers.

For every level of horrors (Mercury, Venus, Mars, Saturn, Jupiter, Pluto, with Pluto being the most dangerous) was a tier of hunters. Ranging from D to S.

D level hunters were mainly highly trained people, but with somewhat weak abilities. They were mainly helpers and cleaners. Like those you see walking around. They used firearms to fight. It would take around 10 or so D-level hunters to defeat a Venus tier. Then there were C tier hunters. They mainly consist of new hunters with promising skill levels. Means they are likely to grow stronger. One c tier still could not defeat Venus level, but they are definitely stronger than D tier.

The real deal comes from B tier and higher. B tiers could defeat several Venus levels easily and fight equally with Mars levels. Several B tiers needed to fight 1 Saturn level horror.

Then A tier, the level which every hunter aims for. They could defeat Saturn level. And several of those could defeat Jupiter level horrors. The Jupiter level horrors are very rare. But they drop the very valuable cores. They might contain very strong abilities or be crafted into a very strong weapon.

However, the strongest types of horrors are Pluto levels. They are truly horrifying. One Pluto level could potentially flatten any city to the ground. Well, in our history we only encountered 3 of those. Two during war and one quite recent. I think about 50 years ago. And we successfully defeated 2 of them. One escaped… The last one…”

“Mirage…” said the young researcher.

“Correct. The dragon Mirage. The beast was so strong he flew by several cities, destroying all of them. He was so fast we could barely detect him. Our strongest warriors almost all perished fighting him. Well, at least we made him flee. I consider it a victory.”

“What if one occurs now? Could we defeat the Pluto level?”

“Well, this is where the S class comes in. The Constellations. The government, all the clans decided to create and fund a group of people. Strongest of all. The best. They were called Constellations. They were specifically created to fight Pluto levels. All the most talented people we had, we trained by the best hunters there were. Mirage showed us that we are still not ready for those creatures. That is why we decided to train the strongest hunters to become even stronger.

Do you know why I said A tier is the tier hunters aim for? It is because you cannot aim for the S tier. They are simply on another level. Okay, that is it, now go back to the screen. Make sure to keep me updated on the energy readings!”

“Yessir!”

Somewhere in a distant place from Earth, a place where no ordinary people can be, a group of people were standing. They were standing in front of a very beautiful lake. The lake was located in the forest, full of tall green trees, almost covering the sky. A tall waterfall was falling into the lake. A piece of nature yet untouched by humans. That was because the place was not the typical forest on Earth.

“Do you feel it?” Asked a tall buff guy with lots of protection on him. He almost looked like a knight. He had two shields attached to his forearms..

“The immense calmness and beauty of this place, which kinda makes me wanna puke, or something very scary under the lake I am looking at?” Replied a very beautiful woman. She had long pitch black hair almost touching her waist. She was wearing very light armor and had no weapons. Only two metal gauntlets on her hands.

“This is no place for jokes, Alice” replied the shielded warrior “You better be careful, do not act reckless. Remember what happened last time. You spent a week in a hospital after.”

“Yeah, yeah, sowwy. What a party buster, honestly.” Replied the girl “well, should I call him?”

She asked, looking at the lake.

She gave a short wink to a shielded warrior, which made him blush quite hard. She then proceeded to go towards the lake, holding her hand in front of her, as if she was about to snap her finger. Not waiting any longer she snapped her fingers and a very loud sound was heard. The sound was so loud that the lake started to vibrate and had ripples all over the place.

“Team, get ready for the fight. This horror is Saturn level one! Any wrong move and we die. Not fighting to your hardest, and you die. Now make sure you all survive otherwise I am personally gonna end all of you!”

Right after her speech, the lake started bubbling. And the large, dark shadow from underwater appeared. It started to grow bigger and bigger.

“This one is a big one,” said a rather small girl. Also she looked like she was still in middle school, she was much much older. She had very bright pink hair and she was eating a lollipop. She had two daggers attached to her waist.

“Do not eat, while we are on a mission” said a man. He was average height but had quite long hair. They were tied in a ponytail. Unlike others, who had cold weapons, he held a fire rifle. Yet it did not look like an average military one. It was emitting blue energy from it.

“Sure sure” replied the girl looking at the lake.

The water on the lake started to foam. Incredible amount of bubbles started to grow.

And the steam started to come out.

“He is heating the water,” said the man with two shields. “It is now about 100 degrees I reckon. Everybody, do not, I repeat, do not fall in water!’

As he finished his sentence, the beast finally emerged out of the lake. It looked like a giant serpent about 20 meters tall. Its scales were glowing red and it was looking directly at the girl.

“There is nowhere to run, nowhere to hide, we will fight the beast and remain the victorious one!” said the girl, getting ready to fight with all she has.

Somewhere very, very far from this place, was a boy, who was standing in a golden field, looking somewhere in the distance.

“I will never defeat this creature, I should run and hide!” said Atlas looking at the creature, which resembled a cat.
