Teaser: Red vs Blue

On that island of Remmant known as Patch, you could find a blond young man with glasses and a few elegant clothes like the wealthy people of Atlas but also with more vivid colors than the typical black or white that is usually used in those places.

The young man was walking with a briefcase in hand and a black cane with a golden handle, the young man was walking because he was going to go to a house in the town, despite his age as a 17-year-old, he was inspired by his father would begin to help people, not as a hunter as many dreamed, but as a person related to the medical world despite not going to a medical school, he still had medical experience and knowledge since he has been working as a medical assistant at his parents, not to mention every night that he spent reading a book on plants in his room, despite the fact that his parents are his inspiration and he even wants to enter the same world as them, the young man does not want to be a general practitioner or a surgeon, which he aspires to the young man is to be a pharmacist since he considers that despite the advances in technology by places like Atlas, or even people with their auras, the world of medicines and serums was inefficient and that was something he wanted to change.

After a few minutes walking, he heard something that was not supposed to be heard, what he heard was a scream from a person, without further ado, he ran at full speed towards where that scream had originated, only to see a group collecting herbs somewhat hurt being chased by a large group of Grimm of the Boarbatusk class, seeing such an event happening to his eyes he began to hear a voice in his head.

"Come on Beren I know you want to help, give me control and I promise I won't do anything to those people, I just want to have fun with those black pigs with white parts"

The blond boy turned to the side of his head to where he thought he heard that voice and saw a person floating next to him but what stood out about that person were only 2 things, the first was that apparently only he could see it and the second it was that he was an exact copy of the blond, the same face, the same clothes but what distinguished him from the blond were his hairstyle while the blond's was a well-done and well-fitting one that of his counterpart was as if he did not know a comb in his life, another change was his teeth which were like sharks if they had to be compared since they were extremely sharp and the most symbolic change were his eyes, instead of being blue like many serums, they were red like blood itself.

"But Ragna, we have to get to see the patient, our father finally let us try my medicines on a person, trust me now."

You could see a bit of emotion on his face as he prepared his staff to start fighting, Ragna, as that floating person had been called, was surprised because if Beren prepared to fight, it was because he really wanted to get to that appointment, without further ado Ragna let out a growl of frustration.

"You win idiot, when I'm done with those grimm I'll return your body, but you owe me a drink and that it's Wisky is the word of a man."

Beren turned to see Ragna with a surprised face, since when he made a promise with his "man's word" it would mean that he really planned to fulfill what he said since despite Ragna's violent tendencies he never broke the law. promises from him

"Okay Ragna, but if you can do it fast I would be more grateful"

"Yes, yes, yes enough talk and more action."

Without further ado, Beren took out a serum from his briefcase which was injected into his neck directly into one of his veins, which caused dizziness and later began to wobble until he was leaning against a tree. The blond's eyes began to change their color to those red and he quickly put away his glasses, after a few seconds the blond began to laugh like a maniac and messed up his hair, it was no longer Beren, now it was Ragna who opened his eyes to leave running at a high speed towards Grimamn's group. Without warning Ragna using his staff but taking it from the middle of this step to become a double-edged sword and without wasting any more time he nailed one of the sides into the first Grimm Boarbatusk but there was something curious, normally this type of Grimm was known for having a very strong armor to the point that to secure its door you have to hit the bottom of the Grimm but Ragna had pierced it with his weapon using only force.

The noise of the armor and also Ragna's maniacal laughter caused both the group of Grimms and the group of people to turn to see the blonde.

"Come on pigs, here I am, say oink, oink like pigs that are like this it will be more fun to kill them"

The Grimm running towards the blonde's direction to attack him but one of them decided to use the characteristic attack of his species, he transformed into a ball with a hard casing which he accelerated to be the first to try to run over the blonde but he instead of move to dodge or prepare to block the attack, he only extended his arms ready to receive the attack without stopping laughing.

Ragna at the moment he was going to receive the attack and using his open arms he caught the Grimm with his hands using his strength to stop the attack.

"Is that all you got? I haven't even used my aura, come on give yourself a damn challenge!"

After yelling at the Grimm, he took the one he had stopped to use it as a sack and hit the other Grimm who came up and were about to hit him causing everyone to move away and be hit by someone of his own kind, Ragna without realizing by his strength ended up breaking the fangs that protruded from the Grimm and realizing he released a slight sigh.

"Aaw, my toy broke"

He said feigning a slight feeling of sadness for later, before the fang disappeared, he nailed it to the Grimm's body, killing him and then began to laugh.

With his double-edged weapon he jumped to the Grimm group and separating his blade into 2 blades, one for each hand and as if he were a butcher he began cutting each Grimm part by part and delighting in their grunts of pain until both cuts ended up dead. and vanishing in the wind only leaving that black liquid.

Ragna plunged one of his weapons into the skull of the last Grimm.

"Did you see that? This is Ragna's power and my reward, the delight of hearing his grunts of pain and the pleasure of killing them with my bare hands?!

The group of collectors did not know how to look at his savior since on the one hand he was extremely grateful but from afar they could see his violent tendencies. Ragna finished laughing and gathered his blades to turn it back into his double edged sword and later into the staff.

"A promise is a promise Beren"

He without further ado closed his eyes and the dizziness returned and staggered for a few seconds and then his eyes bored and they were blue again.

Beren returned to his body and began to arrange his hair, his clothes and put on his glasses, he turned to see the group that had just saved this Ragna and with his briefcase that it was a miracle that Ragna did not want to use it to hit the grimms began to approach especially the one who was wounded.

"Excuse me, notice that he's hurt, I'm going to treat his wounds, of course if you don't mind

"No problem boy, now that I see you I know who you are, you are the doctor's son."

"Hehe, yep it's me, well with his permission"

From the briefcase he took out a serum and some bandages, he directly injected the serum into the wound with a new syringe and later bandaged the wound.

"I'm done, in a few minutes it will be as good as new, now if you'll excuse me, he's calling me and I have to run"

Without further ado, he ran away without letting the people thank him for having helped them until he reached the house of a family where he saw the son of the couple, he had a cold, from his briefcase he took out a yellow serum and later gave it to the couple.

"Your son is going to be fine, give him a spoonful of this serum morning and night for 2 days and he's going to be good as new.

"Thank you, your father sure must be proud of you"

"Thank you"

With a big smile, he left the house on the way to his house to prepare ma serum and to get Ragna's whiskey, something that the 2 had in common besides his physique is that he always kept his words.
