THIS IS THE FIRST THAT NEEDS TO BE READ.

I'll be honest, THIS part right here isn't the story. I have created a story but this is all the background parts of my stories circling Yugioh. I hope people will read and tell me what they think of my ideas. Maybe later I will post my actual story. I'm also going to split this up into different segments, different explanations of the intended character being Seto's sister. If it gets confusing at all feel free to comment.

The story of Seto having a sister is actually one I've been working on for years. And I mean YEARS. I'm 20 and this is a story I've had in mind since I first saw Yugioh. That being said I haven't been WORKING ON the story for that long, I work on it here and there but the story has stayed the same over the years, so much so that I can't bear to change the name of the character. I named her Sareika (pronounced SA-REE-KUH). I wanted something that sounded like it came off the show Yugioh; I didn't go off any real language. I've had that be the name for years and it's not really my favorite anymore but it would just feel wrong to change it now.

The background story of all this goes back to when Seto and Mokuba are at the orphanage; I kept all that the same. Gozu arrives and adopts them just like in the show. However my version is that Gozu not only has a son, Noah, but also a daughter named Sareika who is just one year older than Seto. So upon their adoption, Sareika becomes step sister to both Seto and Mokuba. Sareika, unlike her father and Seto in later years, is kind, caring, softhearted and sometimes soft spoken. She speaks her mind when necessary, sometimes telling Seto off; there are moments growing up when Seto wouldn't acknowledge Sareika as his sister and treats her cruelly and she takes this very much to heart as years go by, so whenever the moment calls for her to speak against her brother about this, she does. Sareika also has a heart condition which makes it difficult for her to do anything that would get her heart rate up, therefore Sareika is unable to partake in the game of duel monsters. (example: when you watch an explosion up close, it shocks you and knocks you back, that's what duel monster games are like for Sareika) they're too much on her heart. So she's never played in an arena or using Seto's technology. She is able to play on a simple surface like a table, where the monsters can't become holograms. Sareika does have her own deck, composed of rare fairy cards but in my story they are in a box sealed behind a glass casing and she rarely takes her deck out.

Sareika grew up rather humble and treated her brothers with great respect, even accepting the torment from Seto, she rarely spoke out against him as a child. When the show enters the period of Noah's world, you find out Sareika was beaten by her father as a child. Without Noah alive Gozu became hostile and would frequently hit Sareika. Word about this spreads to outside sources and one day there's a social worker who shows up to Gozu's manor. Luckily Sareika answers the door and shoes the social worker away. Later in Noah's world (i picture this taking place when the gang all finds out that Noah is actually Gozu's son) Seto finds out that the social worker was there to take Sareika away but she denied the rumors of her abuse and opted to stay in the manor. She explains she did so out of love for Mokuba. She knew that if she'd left the manor, Gozu would take his anger out on Mokuba. Gozu would've never touched Seto, his protégée to the Kaiba Corp Empire but Mokuba being the youngest would've been the one to suffer from Gozu's wrath and frustration. Also in Noah's world Sareika confesses that she never told Seto or Mokuba about her father abusing her because she believed there was nothing either of them could've done to stop Gozu. In my story I have Seto say something like 'why didn't you tell me' to which Sareika replies 'what could you have done' and then Seto basically becomes shocked saying 'what could I have done? I took over his company' mainly saying that if he was able to take over Gozu's company, then he could've easily made him stop abusing Sareika. But Sareika goes on to say 'It wasn't your burden'

So in Noah's world a different light is shown onto the Kaiba family. Despite having grown up with Seto for 6 years (from the time of his adoption to current Yugioh time), Seto was never really kind to Sareika, not like he was to Mokuba. Yet he'd allowed her to live with them at Kaiba Corp headquarters and he doesn't totally treat her like Yugi and his friends. Whenever he would insult her, she'd remain quiet or brush it off, she knew Seto enjoyed getting a reaction, that's why he picks on Joey. But after the trip to Noah's world, Seto begins to feel softer towards Sareika. He sees the torment she endured, from both him and Gozu but what really wins Seto over is knowing that Sareika stayed at the manor for Mokuba's safety. Towards the end of being in Noah's world, when Seto is dueling Noah, Mokuba is hypnotized into being on Noah's side. Also by Noah's side during the duel is Sareika; everyone believes she's being hypnotized like Mokuba but when they look at her eyes, they notice they're completely normal, not blacked over like Mokuba's. It's noted by Sareika that she's beside Noah of her own free will. She explains that Noah is her real brother and she must stand beside him. Seto tries to convince her otherwise just as he tries to convince Mokuba. Anyways, the duel plays out just as in the show. When Noah's world is about to crumble, Sareika is still having second thoughts about going back with Seto and Mokuba. She chooses to stay behind with Noah and die (when Noah's world blows up) but Seto puts his hands on her shoulders and says 'he's not your brother anymore. He's gone. Mokuba and I are your brothers now. We need you. I need you.' And after hearing that Sareika realizes that Seto's right and she quickly goes with him as him and Mokuba run to get on the blimp. Seto throws Mokuba and Seto and Sareika hold hands as they jump together.
