A long time ago in a world called Isalia, beings with great power are teleported, summoned, reincarnated to this world from Japan, these beings are called Isekai Warriors. These beings shape the world with their power, some see them as a threat others as a ray of hope others as a threat that must be eradicated. These thoughts unleashed a great war that shook the world, one Isekai Warrior rose above them all. His name is Gallion Bane, the most powerful Isekai Warrior of all who along with his companions defeated the world's greatest threat Alix Kill, an isekai warrior who sought world conquest of the world of Isalia. Thanks to this war, the world returned to its original glory but some places were afraid of his power so they required the Isekai Killers to never set foot in those places again.
After a while, Gallion disappeared leaving a void in the world... for now...
In the forest of Edonai, there are the dryads receiving the sunlight, but among them, there is one that attracts attention.
-How boring it is to sunbathe. -A kind of Dryad, but with masculine appearance, with fire in his left forearm, Ice in the right, stone in the legs his body that are joined by the torso that is wood with a layer of air that covers a part of his face with a head full of leaves with a face of magic flame that changes color with which he can communicate.
-Sunbathing is not boring, Ketil, it is part of our nourishment," replied a beautiful, mature dryad.
-I should be helping the world of the Isekai Warriors like my father," Ketil replied.
-Your father was a great man, it is true, but the world no longer needs him, everything is in peace and tranquility, the only thing that should be important to you is to defend the forest from any threat that has arisen. As for example the henchmen of the sorceress queen who bother me daily. Ah, there is just one of them go and return him to his dungeon once and for all," answered the Dryad.
-All right, mother if you say so. I'll kick his ass so hard that he won't come back. Again," Ketil replied, flying away on wings of plants combined with air. Soaring through the air until he reached the henchman.
-My lady Kanon, I know that young Ketil has fought against them, but..." answered a fairy passing by.
-Don't worry, I always keep an eye on him so that he doesn't do anything senseless. -Kanon answered and added, "I always keep an eye on him.
-Good morning, Shokan, how is my favorite living armor. -Said Ketil standing high up in a tree.
-Ketil Greenfield. -Shokan shouted.
-Same here, Shokan Bytes get ready to finish you off again..... Although you could repeat the reason why they want to conquer the greenfield forest that I forgot. I don't understand why they are so persistent if we are only a forest of peace and tranquility," Ketil answered.
-You're stupid or you don't know why the hell you defend your home. -Shokan answered.
-No, not stupid, you metal-talking piece of... visionary metal," Ketil replied.
-Whatever, we are going to steal the heart of the forest to conquer the Isalia world, once and for all. -Shokan answered.
-Unfortunately, I, Ketil Greenfield, will not allow it, so less talk and more action," replied Ketil who is surrounded by the army of metal that riddles him mercilessly, but from the floor come out some stalactites of gems that impale the whole army except Shokan.
-Now, it's you and me. -Said Ketil who looks at him from the front.
-Incredible those stalactites went through the Meradium which is supposed to be impenetrable. -Shokan answered surprised.
-I am Ketil Greenfield, protector of the Greenfield Forest, reality as you know it is my whore, now prepare to be destroyed once again," exclaimed Ketil who rushed towards him with a sword made of the same material as the stalactites to kill him, but the metal of the sword withstood the impact of the sword.
-Impressive, but not enough Shokan," replied Ketil.
-You have always been a worthy opponent, Ketil Greenfield. That's why I was prepared to face you once again," Shokan replied, swinging his swords brutally. Ketil hits him with a headbutt that knocks him back. He summons a stone from the floor to make him fall to the ground, summons a stalactite that impales him in the chest and lifts him up so that Ketil cuts off his limbs and crushes his head to play soccer with it and then absorbs the metal of the fallen soldiers and Shokan's sword.
-There, that was fast," said Ketil who sees all the mess and his branches stay with the rest of the metal until leaving everything clean and added. -I will use that metal for another occasion.
Ketil sees the horizon so he reaches out his hand, at first he goes walking then running towards it, but he is stopped by his mother with some vines that are embedded in his body.
-Stop there, Ketil Greenfield, remember to protect this sanctuary from the hands of our enemies, don't let your curiosity get the better of you. The world is not ready for you, nor you of it. -Kanon, who is behind him, answered.
-All right, mother, if you say so," replied Ketil as they returned to the forest. Ketil is in his tree house throwing and catching a stone.
-The world is not ready for you, nor you for him. What does she know, my father traveled the world and fought to defeat the demon king, among other threats. I will see what my father has to say about it. -Ketil said while talking to himself. He gets up and goes to the other end of the forest where there is a lonely tombstone, which says here lies Hiro Maeda.
-Daddy... Daddy, Daddy, Daddy. -Said Ketil is touching the tombstone of his father as if it were a door. Seeing that he doesn't answer, he steps on where his body is located and takes out his father's body, which is incorrupt.
-Son, for the umpteenth time let me sleep. -The father answered.
-Daddy, how are you, how are you feeling," Ketil answered.
-You didn't hear me or what? -Answered the father.
-Of course I heard you, father. -Ketil answered.
-Oh son, tell me what I can do for you. -The father answered.
-My mother won't let me go out into the outside world. She tells me it's a dangerous place, that's true," replied Ketil.
-The outside world is dangerous and more for someone like you, I know why I tell you, I was an Isekai Warrior, I spent a lot of work for someone like me, I dropped the sword because I want to be in peace until the end of my days, son obey your mother, the outside world is not worth it, especially for someone like you, you don't even want to be human in the first place. -The father answered.
-Well, you're right about that last one. Thanks daddy. -Ketil replied and let him rest and then went home to sleep.
Kanon and Ketil's father talk.
-You know honey, you should let Ketil go out from time to time, the man thanks to us is advancing by leaps and bounds and one doesn't know who can be the lucky one to steal the heart of the forest. -The father answered.
-Gallion," Kanon replied.
-Don't call me like that, Kanon, that man is dead, now I am Hiro Maeda, call me by my Japanese name. -Answered Hiro.
-Okay Hiro, but for me you will always be my Gallion Bane, my hero and savior," answered Kanon hugging him with his back.
-Oh, Kanon. -Hiro answered and added. -You have to let Ketil meet humanity eventually because of you Ketil rejects his humanity, if the minions of the sorceress queen know about this, they will take advantage of that weakness and it will be your ruin.
-You're right, I'll see what I can do. -Kanon answered, thinking about it and stopped hugging him.
At that same moment, the henchmen meet with the sorceress queen.
-Well, my minions, what are your suggestions? We have lost several of our companions and minions because of him," replied the sorceress queen who is a humanoid iron lady sitting on a platinum skeleton throne.
-I have an idea, your majesty. -An evil dryad replied.
-Say your suggestion, Evilyn Gaia. -Replied the sorceress queen.
-I don't know if you have noticed, but don't you think that instead of confronting him we should convince him to join us by giving him the gift of freedom? -Evilyn answered.
All agree with Evilyn except one.
-And how do we know this can work," replied one vampire.
-Because I monitor Shokan in his combat and I realized it. -Evilyn answered.
-All right, I'll trust you, Evilyn. -Replied the sorceress queen.
The next morning, someone attacks the forest shield and this attracts the attention of Ketil who goes to find out.
-Strange, that Evilyn is not here. -Ketil said, talking to himself.
A scream alerts him. He goes to where the scream is heard which turns out to be a human being devoured by a carnivorous plant, but Ketil rushes over and cuts her with a sword and rescues her by regenerating her with his vines by transferring healing magic around. He turns into a human so as not to terrify her.
-My hero," answered the fainting girl.
-Son, stay away from that human. -Said Kanon who sees him holding her.
-But if she needs help, let me return her to her village at least. -Ketil answered, making puppy dog eyes at him.
-No, I will take her back. Now go back to the forest. -Kanon answered.
Ketil returns to the watchtower, where he spends his time watching over the forest. Time passes and his mother does not return.
-Now that I remember, since when is there a village around here? I have to investigate more about it, although I can't leave here. I'm sorry mother, but I'll have to break the rules," Ketil thought as he went to look for his mother.
