(Kai pov)
This may sound impossible, but hear me out a bit...
"I was Isekai'd into another world"
Yeah, I know what you're thinking, that I'm crazy and I must have gone insane. Considering reincarnation only happens in anime.'
Reincarnation is the belief that the soul or essence of a person continues to exist after death and is reborn into another body or form. This belief is held by many religions and philosophical traditions around the world, including Hinduism,Buddhism,Jainism, Ancient Greek philosophy, Native American spirituality, and African traditions.
In Hinduism, reincarnation is considered to be the central aspect of the cycle of existence known as samsara. It is believed that the soul goes through a continuous cycle of birth, death, and rebirth, and the type of rebirth one experiences is determined by their karma, or the sun of their actions and thoughts in their previous life. Hinduism also teaches that the ultimate goal of reincarnation is to achieve moksha, or the liberation from the cycle of existence and attainment with the ultimate reality.
In Buddhism, the concept of reincarnation is tied to the idea of impermanence, as all things are said to be constantly changing and in a state of flux. Unlike Hinduism, Buddhism does not believe in a permanent self or soul, but instead sees the self as a collection of constantly changing experiences and phenomenons. In this view, reincarnation is seen as a continuation of the impermanent, changing nature of the self.
Jainism also holds the belief in reincarnation and teaches that the soul is trapped in the cycle of birth, death, and rebirth, due to past actions and karma. Jainism places great importance on the principle of ahimsa, or non-violence and encourages its followers to live a virtuous life and to avoid actions that cause harm to others, in order to reduce the accumulation of negative karma and eventually attain liberation from the cycle of reincarnation.
The Ancient Greeks, including the famous philosopher Pythagoras, believed in reincarnation. They held that the soul was immortal and that it was reborn into another after death. Pythagoras and his followers believed that the soul was reincarnated in order to gain knowledge and experience, and that the ultimate goal was to attain a state of pure consciousness that was no longer sustained to reincarnation.
Native American spirituality also includes beliefs in reincarnation, where the soul of the deceased is said to be reborn into another body. This belief is often tied to the idea of a spiritual journey, where the soul moves from one form to another in order to learn and grow. In some Native American traditions, it is believed that the soul can be reincarnated as both human and non-human beings, such as animals or plants.
As I continued to think I heard a voice.
The moment I opened my eyes I was greeted with smiles and looks of love.
There were also colorful particles floating in the air.
What are these? Is this magic? I curiously wonder.
Focusing and slowly lifting my small underdeveloped arms, I tried to catch them using my tiny hands.
The observers who I presumed to be my parents looked at me with unconditional love and fascination.
I opened my palm, it floated again and escaped.
Is this magic?
It form is a circle. I also felt an energy running through my veins as my skin touched it.
I'm certain this has to be magic.
While I was thinking A black haired man with a pair of black eyes, which I am certain is my new father, opened his mouth.
I can't understand any words he said.
Aside from Japanese, I've learned English, French, Chinese and many more in my past life.
Right now, it's an entirely new language for me.
I better learn it as i grow up
Communication is essential after all.
As my thoughts slowly drifted, I heard an ear-piercing sound on my side.
I moved my muscleless hand to the origin of the voice and there, I found a black hair child following his example I started to cry to as to not be suspicious.
"Waaaaaaaaaaaaaaaaaah!"
As black haired girl similar to the woman who I presume is my mother, gently picked me up and stared at me and my brother.
But I wasn't focused on her.
"I can feel it"
I can see it these particles. This world is full of magic.
As the black haired girl rocked me to calm me down I was deep in thought.
"Is it truly possible now? Can I fulfill my dream?
Before I could answer my question, everyone went quiet as I looked around. I see my family looking confused and in a state of confusion myself I didn't know what to do. Before I could ask myself what happened I got a whiff of something.
I turned my gaze to my brother.
"Did he just poop?"
◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇◆◇
8 years have passed in this new world. I was born from a noble family with the surname Kagehashi. For generations, members of this family have trained to become dark knights, one of the many types of military forces who use magic through their bodies and swords to power up and slay enemies in battle.
It took me 5 months to gain consciousness in those 5 months I was image training in my mind something i learned from dragon bolt z a anime from my world this ability allows you to train against opponents stronger than you so I trained against the false god statue for 5 months straight master martial arts from boxing to systema and learning how to control my magic.
I experimented with it so much I came up with new ways to train for example if you break and repair your magic circuits they get bigger each time you do it or if compress your mana and expand it you can simulate a mana explosion but if your not used to it your mana circuits are going to burn.
Aside from that, I'm the Second child of the Kagehashi family. I have an older sister and a twin brother. Said twin brother is a pain in the ass sometimes but that's what makes me like him even more.
My older sister is the heir of the Kagehashi family even though in medieval times it's supposed to be the son but when my father made us fight for the title of heir I threw the match. I usually overwhelm the many sparring partners I've faced, winning children's dark knight competitions in the capital going toe to toe with my prodigy older sister making her look good. While I achieved greatness at a young age.
My younger twin brother Silas Kagehashi or Sid as we called him after I said he reminded me of a sloth named Sid. But back to what I was saying, I always win when we fight. I easily overwhelm him when we spar without breaking a sweat. That is, if one would simply just watch the match. He is fast. Too fast that those who don't have Mana vision won't notice how he switches from one spot to another then returns to his original spot. He's a little faster than me. I'll give him that but I'm still better than him with a sword.

Timeskip 3 months (Silas pov)
Kyahhh! I let out a battle cry as I rushed towards my older sister Claire.
She dodged my rush and broke my guard pushing me back a few meters forcing me to the ground.
If I appear weak to you I'm not. I'm just being background character A. If I want to be the mastermind in the story I have to be the perfect background character.
"You're too strong , no fairrrrr!" I whimper out doing my normal routine as I let her kick my ass. But I can't allow myself to win. If I want to become the mastermind in this story, I've got to become the best background character I can be.
I looked to see my sister Claire. She's a beautiful young girl with black hair and wine red eyes, even though she is young she is very refined, a woman in the making.
I hear Claire sigh under her breath before giving me an intense glare.
"Stop whimpering like that. To think that my brother can't evade such a simple strike. You bring shame to the Kagehashi name."
As she said that, she then approached a couple of boulders left here by my older brother.
" Our family is of a noble lineage; our lineage gives birth to many powerful spellswords. Do you understand that at least, right?
I nod keeping up my background character act.
"Of course onee-chan you and nii-chan have explained this before."
When I said that Claire sighed out. She then walked forward and raised her hand as a small aura-like flame had appeared on her hand. As she then looked back at me with an exasperated expression as she sighed out."
"And yet your magic control is no better than an amateur. Not just that you're completely unremarkable in sword play or anything physical. At this rate, you won't ever be more than an apprentice. So, in hopes of your future, observe."
As she said that she moved her hand across her sword, as her energy started to spike.
"If you manipulate your magic to strengthen your body to change your speed or to strengthen your sword…."
She then proceeded to attack one of the boulders nearby, completely destroying it. This technique is basic in this world; kids are required to learn it to learn how to manipulate mana.
Claire turned to me with a smile on her face.
"Even smashing boulders will be an easy feat for you."
"Wow onee-chan!" My act is marvelous if I do say so myself.
"You're amazing onee-chan! What's your trick!?"
She smiled at me as she ruffled my hair.
"It's still impossible for you.The sun will set soon, so we'll end training here for today.
She put her sword away as she looked at me.
"I'll leave the rock cleaning to you, since I have other business to attend to."
I looked down damnit Kai where are you? Why am I the only one that has to clean? "Aw…."
As Claire was about to leave, I asked her one final question.
"Onee-chan?"
"Yes, my dear brother?"
"What business do you have to attend to?"
When I asked that, I felt something. An evil and dangerous feeling crept from Claire however she just smiled innocently at me.
"To check up on your twin."
With that Claire left the backyard in search of my twin brother Kai Kagehashi.
I pray for your safety nii-chan

(Claire pov)
"Now where is my foolish little brother at?"
I thought to myself as I walked around the Kagehashi manor.
I'm very adamant about my little brother's training even though Kai is stronger than me. I can tell that much but I can't allow him to run around free, while Sid is training hard.
"Then again… Sid needs to practice…"
As I thought this something melodic can over me.
A sound.
One which was so elegant, so profound. One which could hypnotize many with its emotion and history.
I followed where that sound was coming from into the main room of the house, and there he was.
Playing an elegant piece. He was sitting at a piano and was playing the keys so freely. Some of the nearby maids had stopped to watch and were in awe. The sound and feelings transmitted couldn't be defined.
I looked at who was playing the song, the Moonlit lullaby.
It was a young man with black hair and grey eyes. He had a normal set of clothes, for house usage. He currently had his eyes closed, as the music seemed to dominate everything around him.
Finally, when he did finish, he stood up, still with his eyes closed, and did a small bow towards the maids of the house.
It was a small gesture, for being his audience. Significant, yet very important.
The spectators clapped and finally I decided to let my presence be known.
*Knock Knock*
I walked into the room until I was right beside him.
"Kai…"
Without losing his smile, Kai turned and looked at me, with his smile ever so present.
"Hello, Claire onee-chan. What seems to be the problem?"
I just stare down at him with a small smile
"You didn't come to our training session, Kai."
When I said that Kai looked away from me in embarrassment.
"I'm sorry Claire. I lost sight of time.
He said as he bowed to me.
"I promise I'll make it up to you"
Even though Claire was angry, she stared at Kai in wonder. She knew Kai always kept his promises. And he was definitely better at doing it then Silas. Plus…she was a brocon.
With a sigh that made Kai smile internally she hugged him and left to go to her room.
I let go of a heavy breath I didn't know I was holding.
"Oh boy. That was close"
I then looked towards my palm, as a black energy sphere appeared on it.
"I know Claire has all of the best intentions, however I had long mastered my mana. I was able to feel it ever since I was a baby. Maybe my research in my previous life had a good factor into it."
