There are various types of monsters in this world. Though given the time frame I am currently in right now, the monsters aren't really all that powerful. From what I can recollect, the monsters go from Level 0 to 100 and at each 10 levels, the power of each monster increases by many folds.
To put it in simple terms, the monsters are divided into the following groups.
[Grade G: lvl 0 to 10
Grade F: lvl 10 to 20
Grade E: lvl 30 to 40
Grade D: lvl 40 to 50
Grade C: lvl 50 to 60
Grade B: lvl 60 to 70
Grade A: lvl 70 to 80
Grade S: lvl 80 to 90
Grade SS: lvl 90 to 100]
It needs to be mentioned that a lvl 10 F Grade monster will be much stronger than a lvl 10 G Grade monster. Each monster also has its own system, with which it can evolve to its most appropriate path.
Until Grade B, the advancement / evolution is mostly based on the instinct, environment and situation. A chimera can become a general chimera or larger chimera, or it may unlock a new path of evolution all together.
After B Grade, that is A Grade, is what changes the whole adversity of the monsters on a fundamental level. After attaining Grade A, the monsters gain intelligence, that is the ability to make judgement and calculated decisions. It may look really simple at first, but when you combine the monstrous traits they have and the stat points they never used in their entire life, that's been made available to them… that changes the whole game.
That is why the monsters above A grade are not given any chances to survive and are ordered to be killed on site… that is, if the person in question has the ability to do so.
There exist systems that have similar ability to what a monster tamer would have, allowing them to manipulate / tame the monsters according to their own needs, so some monsters are captured but only upto grade B.
Last but not the least, different types of monsters have different abilities. Given the right situation, a D Grade monster might be defeated by an F Grade monster; and that takes us to the different danger zones, filled with specific types of monsters where they could enhance their full potential.
The danger zones are under the rule of S rank monsters or higher with each of its own domain. If I remember right, in this timeline, only 7 of the 24 Danger Zones have been discovered till now.
...…..
Zero observed the frog monster in front of him. An E Grade monster attacking the city and hunting and purging through the area.
'From the information, in my previous timeline, I had looked into this attack, this attack was made by a group of Monsters with a C Grade leader. Though the leader was killed by a B Rank monster hunter who was passing by.
This makes things a bit more simpler since all I need to do is to survive the 4 frog monsters,' Zero thinks as he observes the surrounding area slowly and closes his eyes as he waits for something.
-BOOOM!
Someone crashes in between the monster and Zero. A girl who looked like she was in her 20s stood with her orange sword pointed at the frog monster. Her expression was filled with annoyance as she traced the area around. Her eyes passed by Zero, then back at that monster.
'An E Grade, nameless frog to kill and an almost dying child,' she thought as she took a brief look at her system.
[Name: Clair Redfield
Level: 46
Class: Berserker Sword Knight
Mana: 130/530
Stamina: 100/400]
'Guess, I can make do with this much,' She thinks before jumping at the monster as she activates her skill,'[Sword Art of the Royal Knights]'
Zero observes her with solemn eyes as he recalls back the memories of what had transpired before. The more he recalled, the more his eyes turned desperate. He tried his best to find a way to heal himself as he looked around, but no matter what he did, he could not find a way.
'There are 3 more frog monsters, each D grade and mid-level. The E grade monster is just a bait. I must warn her about it. This isn't good. At this rate she will die… I must do something… but what…' Zero kept looking around frantically. He couldn't shout because at this point the sound of fighting covered the whole area and the more he moved, the more pain he felt.
-Drip
-Drip
'Huh?' Zero then felt water drops falling onto him. Looking up at the night sky filled with clouds, Zero couldn't help but feel astonished at his luck.
-Drip Drip Drip
The rain began pouring harder and harder as moments passed by. One must remember that frogs are Amphibians, they are creatures that can walk on land, essentially belonging to aqua habitat. Their true potential is also shown in an aqueous atmosphere.
-Boom
Clair created distance between her and the frog and looked at the frog with an even more annoyed gaze. Recalculating the whole scenario, she once looked at me as if contemplating between leaving me and running away or fighting the monster and saving me.
'Me and my soft heart!' She cursed herself as she once again charged towards the monster as fast as she could. If earlier she had an upper hand against the frog monster, now they were fighting on an equal level.
But the fact that 3 even more stronger monsters were hiding behind to ambush her had basically confirmed her death.
'Although the rain did bring doom to our situation. But thanks to the rain we might be able to survive the whole situation,' Zero smiled as he slowly narrowed his eyes at the fight and began calculating the next few moves Clair would be made against the frog monster. Once he made sure what the next moves would be, he then braced himself and…
