In this world, there exists a power system known as Seal Power, seal power is a knowledge-based ability system where users manifest supernatural abilities through symbolic marks known as seals. Each seal grants one specific, temporary power, and the only true requirement for activation is that the user fully understands the seal and its abilities—without that understanding, the seal will not work. Weaker users must physically draw the seal they intend to use, whether in the air, on their body, or onto a surface, and once the symbol is formed correctly, it manifests into reality and activates its effect. In contrast, stronger users can bypass this step entirely by simply imagining the seal, causing it to instantly appear and trigger its power if visualized correctly. Seals are gained by learning and studying them, and their use places strain on the mind, draining focus over time, especially when using stronger or multiple seals. Skilled users can perform Seal Stacking, activating multiple seals at once, though this greatly increases mental strain and risk. Seals are basically spells and incantations used through symbols.
Legendary Blades are powerful bladed weapons forged from a mysterious ore called mysterion ore. These blade's all have different abilities revolving around the one core concept it's named after. Legendary blades all have kanji in them that must be traced to activate the blade's conceptual powers and abilities, users must speak the name of their legendary blade after tracing its kanji to fully activate its powers. So level 1= base form, regular sword, level 2= 1st form, kanji tracing, standard abilities, level 3= 2nd form, name of the blade, full power, main ability. It takes an extremely long time to unlock 1st form and second form legendary blades, years upon years if not decades. During 1st form and 2nd form, the blade transforms, gaining a new physical characteristic revolving around the single concept it's named after.
Legendary Eyes are rare ocular abilities that were forged with the mysterion ore by mages who wished to overthrow the sword saints after the war with the aliens. These work the same way as legendary blades but are levels beyond legendary blades.
Downside: Seals, Legendary Blades and Legendary eyes all draw from the soul of the user to activate their abilities, so overuse of these systems will erase the user from existence.
(The main setting is a gigantic continent with very olden landscapes, rural cities, villages cobblestone/ wooden buildings, cobblestone roads, horse/donkey transport, gold as currency, etc)
Once, there lived a man named Aizashi Shishiroma, he's a living legend. His skin colour is black, he has black eyes and spiky black hair that flows upward because of his red headband, he wore and still wears the sword saint uniform (Their uniform is comprised of a red shitagi, red hakama, black jika tabi boots. Senseis wear black haori on top of their uniform). He's 5'10 and is lean but muscular as well. He studied swordsmenship at sword saint academy (this is a school where, senseis train kids, teens and adults to become protectors Sol. While they are all students, they also act as the law enforcement/military force for the country. There is only one requirement they must adhere to inorder to join, Every one of the sword saints is required to have a legendary blade. Legendary blades and sword saints were originally made to combat the aliens that had invaded the earth 100s of years ago. After their leader mother Null was sealed away, the aliens fled and sword saints were then used as military personnel and law enforcers, retaining use of legendary blades) from the age of 5, going on to forge his name into legend. He's one of the strongest sword saints that's ever existed, wielding the flame blade and achieving feats such as defeating the corrupt monarch of Sol, sealing away mother null (she was a monsterous onryo that killed 2 billion people by simply screaming once. She also evaporated 3 galaxies before coming to earth), stopping a meteor the size of the sun from destroying the earth, etc.
After retiring at the age of 32, he moved to a quiet village in front of the great ravine of Sol (all villages are outside the nation of Sol). He then married Katherine Kunehane, the strongest known wielder of the shadow blade and having a child with her. Katherine too has black skin colour, black hair, and black eyes. She's 5'5 in height and 50 kg in weight.
9 months later: Their child is born.
Katherine: So precious...
She says, caressing the baby gently in their bed.
Aizashi: (crying tears of joy) Wow... he's definitely destined for greatness like his parents.
Katherine: Oh stop crying you oaf.
Aizashi: I'm just so happy. This is probably the happiest moment of my life.
Katherine: Probably?
Aizashi: Oh no, forgive me love, I meant this is the absolute happiest moment of my life.
Katherine: Any names?
Aizashi: Names huh...
Aizashi taps his chin, pondering.
Aizashi: Xzaivier maybe...
Katherine: Why Xzaivier?
Aizashi: Well it's a name from my favorite book.
Katherine: Alright, Xzaivier Shishiroma It is then.
Katherine kisses Xzaivier's forehead.
Aizashi and Katherine raise Xzaivier, creating the best memories they could ask for.
6 years later, Katherine and Aizashi have a second child named Levine. The family is in their house conversation until...
KABOOM
An explosion can be heard and then screams. Aizashi, alarmed grabs his flame blade before rushing to the door. Aizashi opens the door and looks at the flame engulfed village, and the ridiculously large number of villagers on the ground, dead. Xzaivier rushes to the door followed by his mother, who's holding the newborn Levine. They all watch a strange swordsmen, with long jet black hair, white skin, a bundle of hair covering his left eye, dressed in a black suit with an oni mask on his hip, shoving his blade into a 4 year old child's mouth before hurling him into the flame engulfed huts. Strange swordsmen appears to be wielding a legendary blade.
Strange swordsmen: Pathetic honestly. Stupid little brat.
Xzaivier looks horrified. Aizashi is shocked. Katherine is disgusted.
Katherine: A child?!
Aizashi: (extremely angry) HEY YOU! WHAT HELL ARE YOU DOING AND WHY!? THAT KID DID ABSOLUTELY NOTHING!
Strange swordsmen: Ah... there he is. The man of the hour... Aizashi Shishiroma!
The swordsmen lifts a bundle of hair that's covering his left eye revealing a strange black eye (the entire eye) that has an iris with a bright blue (His normal right eye is dark brown). In his iris the kanji for evil is imprinted.
Aizashi: The Aku no eye? It can't be... if that's really the aku no eye in your eye socket right now then that means you're—
Strange swordsmen: Lord Gimori Aku no in the flesh.
Aizashi: If you're Gimori then that's the demon blade (second strongest legendary blade in history) in your hand right now. How can it be that you're here in front of my home right now you 300 year old freak? You were imprisoned under the mountain of atonement by Titanus Kensei 200 years ago.
Gimori: True, that rat did imprison me. I had control over the entire world and then that piece of—
Gimori takes a deep breath.
Gimori: I'm not here to dwell on stuff that ensued 200 years ago. So I'll just cut to the chase... I used my aku no eye to eradicate the mountain of atonement and I'm currently trying tick off a bucket list.
Gimori flips his hair back before giving Aizashi an unsettling smirk, the aku no eye still focused on him.
Gimori: I've checked off most of the stuff of my bucket list but there is one more task I absolutely must complete. That is my human extinction plan.
Aizashi: Human extinction plan?
Gimori: Yes... I am going to eradicate every single human, except myself of course.
Katherine: Why the hell would you do that you sick bastard?!
Gimori: Humans do nothing but destroy. You all are blight upon this beautiful world and I'm taking action.
Gimori's grip tightens around his demon blade before looking at the newborn Levine in Katherine's hands with his Aku no eye.
Gimori: What a cute baby boy... too bad I can't let him live.
Gimori stops the child's heart with his aku no gaze. Katherine screams absolutely shocked before crying profusely. Xzaivier is absolutely stunned, too shocked to even react. Aizashi stares, eyes wide as his newborn's breaths fade. Rage silently builds inside him. "My boy..." he says in his mind.
Aizashi: Too bad... you won't be able to carry out that human extinction plan of your's...
Aizashi removes his sheathed flame blade from his hip, raising it overhead before unsheathing the flame blade slowly. After unsheathing his flame blade he throws the sheathe onto the ground before scowling at Gimori, his blade's steal shining, still being overhead. The seal in the blade still hasn't faded even a bit after all of these centuries it's lived through and all the hands that have touched it.
Aizashi: Because you'll be too busy feeding worms in the ground to do so.
Gimori: (in his mind) This imbecile must not know that my aku no eye always resurrects me whenever I die, regardless of the cause.
Gimori smirks.
Gimori: These are the types of opponents i enjoy crushing!
Gimori charges at Aizashi.
Aizashi: Katherine.
Katherine: Yes love?
Aizashi kisses her.
Aizashi: I love you.
He kneels down to Xzaivier's height before hugging him.
Aizashi: I love you son.
Xzaivier is still too shocked from Levine's death a few seconds ago to even say anything.
Aizashi stands up again.
Aizashi: My love, please get Xzaivier out of here.
Katherine: Alright.
Katherine takes Xzaivier's hand before rushing to the great ravine behind their village. Gimori traces the kanji on his blade, finishing in less than a second as Aizashi flashes towards Gimori, Gimori's blade grows a single horn and the two clash. Their clash shakes the ground and air alike as they glare at eachother.
