he have that cristal ever since he was born it was unknow to his family as for why as the record show no one have an cristal and later after an doctor and mage ispect it they conclude is some sort of magic core as they theorize is to have more magic and control on it..as there was not record of something like that but jason's mother decide to keep things an secret as she know if there is whisper about the cristal it will bring the bad company to jason..worst case he be experiment on..but another thing fo jason it feel everytime he look at it he feel like something is missing..like an part of him is gone..and try to remeber but he can't why exalty is the missing ad flustared him to the point he can't sleep sometimes at night

jason keep look and sight

jason:what is with you it make me feel soo lost

he wonder himseft until he hear an knock

???:brother you awake?

jason:yeah 

the door open to reveal an girl

claire kagerou oldest sister of jason,she is been caring to him since he was boring as both siblings get along too well sure they mild argues sometimes but they always get better with each other an the end,olso claire can be..... an little overprotive with jason at times as jason kinda dislike and tell claire at times he needs to defend by his own will istead rely on her but claire always metion as sister is the duty to protect her younger brother it was an thing even some the maids metion they talk like an couple witch embarrsed the due and deny that

claire:i see you up

jason:yeah

claire notice the cristal

claire:brother again?

jason:kinda hard no too see it

claire nod it was thing ever since jason have the cristal on his chest an first she was curious about the why jason have that but as years pass by jason feel like something is missing at times when he look an the cristal an point he sometimes let an frustation witch make claire feel bad as he want to help jason but she doesn't know how only support him as best she can

claire:i sure you find the feeling

jason:what if i don't

claire hug jason

claire:don't worry you big sister is always be with you to fill that space

she said as jason smile and hug her back

jason:thanks sis

he said as both stop hug

claire:let's go is time for seccion

jason:right

he said put an shirt to hide the cristal as both head out the room,the kagerou family have an story as for generation have trained to become dark knights who are expert an magic to slay they enemies,as jason and claire as one of posible heirs of the family

the siblings walk pass by some maids

maid:hey who you think who go better 

maid 2:i bet claire sama

maid:i bet jason sama he sure he got better

maid 3:maybe for the cristal he got better

maid 4:hey don't say that..you know how painful is for jason sama right

maid 3:sorry

maid 4:but i bet is jason who win

yeah turns out the slblings are both prodigies an the family when comes of sword and magic as both are even trough claire is better an magic while jason is good an swordmanshi

training grounds

both siblings have they sword out as both stab an giant crock

slash,crank

as the rocks were cut into pieces as the kids father along with the instrutors clap an the duo as the kids sheath they blades and bow

instrutor:impressive you two you got better since last time

instrutor 2:is amazing both are even when comes to progress

dad:i have to prodigies that is for sure

jason sweatdrop

jason:{he said that because we are the best}

he trough he can tell if one of then didn't meet the other expectations his father aka bald man will ignore that child he knows that because early on his life he strugger to keep up with claire it was later on he train with her an private he keep it up..and less to say after he metion the theme to his mother she beat the crap out the bald man

claire:hey brother how about an duel

jason:i in sis

instrutor:very well is duel it end when one of you can't continue

both siblings nod as both got ready

bald:soo what you think

instrutor:after see then both are good..but they have diferences

bald:witch is

instrutor 2:well claire is good with magic that is for sure but jason is good an the sword to point supass claire's an fact he learn way faster than her

instrutor:while claire sure show great magic power compare to jason..is like an balance between thoses two

the bald guy trough it was true claire have an strong magic than jason but jason have an superior swordmanship than claire trough the fromer find odd due to the cristal as the amge who check him serve as core..but he figure because he was still young he can't control the magic well

instrutor:all right...begin!

claire begin to attack as jason defend

claire was suprise jason manage to disarm her as the later grab her blade and trhow back at her as claire catch

jason:round 2?

claire smile

claire:go ahead

both attack as they were even

the bald and instrutors were suprise they are even ground the instrutor can see jason have more edge than claire as he have more experience and know how to make fast and accurate attack

instrutor:{both are even but jason sure have more experience and the movement if prove of that}

he trough it was true when he begin he learn way faster than claire when comes to swordmanship an fact he was the faster person he learn an swordmanship even hear claire how he did it and he answer was"i don't know i just feel what to do like i did this before"like it was pure muscle memory witch is weird how someone soo young can remeber how to handle an sword and to the level jason it requires years of training 

crank

that was the sound of claire's sword bleak after an strong strike from jason's 

jason:the duel is over

claire:yeah{he is soo good an the sword}

claire trough it was true jason's swordmanship was better than claire even to the point he manage to imitate the actions of the instrutor perfecty claire ask him how and he metion"i just feel i know what to do"it suprise him compare to his magic witch was weaker than hers but she can see the pontecial jason can go..and she is happy to see the results

the bald and instrutors clap an the dup as both smile
