In just one day, because of Illya and her two maid arrival at the Emiya Residence. Shirou having a disaster and a good this happen at the same time to him. A disaster because Illya, Saber and Rin are still having an antagonistic relationship, even Sakura who always came in the morning to help Shirou in cooking and cleaning look a bit angry because Illya and her two maid sudden appearance.
But because of her good poker face skill not even Shirou or Rin realized that Sakura was angry. And only Archer who can tell the different because of his long experience reading other people face expression.
A good thing for Shirou because Sella and Leysritt was doing a cleaning of the house in a faster rate and cleaner than him. Shirou always having a hard time everyday when he cleaning his house, because the Emiya Residence was very big. And he nees more than two hour to clear all the part of the house.
With Sella and Leysritt help the house cleaning can be done in only thirty minutes.
They also try to cook in his kitchen, but with only one glance from Shirou and Saber both of them didn't dare to cook at all. Because for Shirou his kitchen was the most favorite place in Emiya Residence where he can cook so he can feel relax while Saber was glaring at then because she doesn't want other people to cook for her in Emiya Residence.

That night at Shirou room right after a day that full of chaos because Illya sudden appearance in the Emiya Residence.
"Sigh I feel really tired after a very chaotic day," Shirou said who was lie down at his futon. "I didn't expect that Illya will come here and decide to stay here because Gilgamesh attacking the Einzbern Castle. A lot of thing are different from the time I came from, are all of that is happen because I change the timeline a little bit?"
[This timeline where you are right now can't be said at a past, is more correct to say that this timeline was a different dimension that will have a different ending because right now this dimension and timeline was your new future and the timeline where you came from was your past. In my time as Emiya Shirou I didn't have a feeling for Sakura like you because I only consider her as my little sister, I falling in love with Saber but sadly she must going back to her timeline while at the same time I also have a feeling for Rin and then married her to the point I have a two kid with her. But sadly I stupidly choosing my dream as a hero rather than my own wife and kid. And the most saddest thing for me beside I cannot be with my wife and kid was that I cannot save Illya for her early demise.]

"Archer! What did you mean by Illya having early demise!" Shirou said with a serious tone.
[Because of the magic reinforcement that the Einzbern do to her body so she can have an enormous amount of mana, Illya cannot have a long life. Right now I think she can only have one or two year to life. That magical reinforcement decrease her age significantly. In my timeline I researching a lot of thing with Rin to save her, but sadly there is no way to save her except for a forbidden magic that I and Rin doesn't have a qualification to use.]
Shirou gritted his teeth. In his original timeline, Illya sacrified herself to save him, and in his new timeline knowing she will die if he doesn't do anything making his heart feel really hurt. Because she cannot save one of the most important people in his life.
"Are we really cannot do anything to save her Archer?" Asked Shirou with a desperate look on his face.
[Well because of Zelretch interverne, I found a way to save our sister. The way that I my self feel surprised when I knew about it.]
"You found a way to save Illya!" Shirou shouted. "How! What is the way so we can save her?"
[The answer to save her was reside inside your blood. In the form of Nano Machines that have an ability to regenerate a dying cell in human body, because as long you have that Nano Machines in your body even if your head was decapitated you will not die because your body was supported by the Nano Machines.]
***
"The Nano Machines that you injected inside my body have a function that make me an immortal!" Shirou said with a shocked expression on his faces. "Why did you not tell me about that faster!"
[Because I only remember about it just now! Beside the Healing function of that Nano Machines, if you concentrate strong enough you also can change the shape of your body as long it not to extreme. Like you can change the shape of your hand into a simple sword or a spear. That Nano Machines also have a bit of Dark Matter inside of it, to strengthen the power of the transformation. In the future I think your body can be change completely and fully as long you have enough energy and stamina.]
"So that Nano Machines not only give me an immortallity but also giving me a transformation ability? What was Zelretch thinking by giving me that Nano Machines!" Shirou said who feel angry to Zelretch because he changing him into somekind of Bio weapon. "Did he didn't think about my feeling at all! When I knew that I'm no longer and ordinary human because of the Nano Machines!"
[That old troll will not give you the Nano Machines without a reason, he maybe a chronic Prankster but he will not doing something that will be bad to you]
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
"Sigh whatever, as long the Nano Machines can be used to save Illya, I didn't care about my self being somekind of undead," Shirou said with a deep sigh. "Now what I do is to save Illya using my blood right? And then she will live longer."
[Yeah, but I didn't know what is a side effect that will appear in Illya body right after we heal her. There is chance that she will stuck forever as a ten years old girl. Or better she will change into her real age that older than you a year or two,] Archer said. [Well let just hope that not a bad thing will happen to Illya.]
"Being a ten years old forever will be a pain for Illya, so I hope that thing will not happen to her but if she grow to the point she look like her real age. I have a bad feeling that Sakura, Saber and especially Rin will doing something bad to Illya or me," Shirou said with a pale faces. "Let's just pray for the best that Illya will be cured and then she growing normally."
[Knowing our luck the famous E rank luck the thing that we hope will almost not happen to us and only the worst thing that will happen to us, so let's just hope that you and I will be strong enough to face any kind of problem that will appear in the future. And I think we will be strong enough because of the immortallity that you got.]

"Sigh why did Emiya-kun must bring the Einzbern heir to this house. Even though she was his adopted sister but that girl is still our enemies! I'm sure that she has hidden agenda in her mind by staying here," Rin said while gritting her teeth. "Archer I order you to found out, what is her hidden agenda."
"Rin you must calm down a little, because I don't think that Einzbern heir having a hidden agenda. Because I can feel the connection between her and Berserker already gone. She already lose her Servant and because of that her right as the participant of the Holy Grail War already gone. I think right now she just want to have a safe place to spend the remains of her short life. As a half homunculus that already modified by the Einzbern so her body can contain a lot of magical energy. I think her lifespan is only one or two year left, she was really a poor little girl," Archer said after he remember the thing that happen to his Illya.
"How you can know a thing about the Einzbern heir so much, Archer?" Asked Rin who feel suspicious to Archer.
"Before you ask me to find information about the Einzbern I already search information about her and the other Master and Servant. In case we need the information about our enemies, information is a power Rin. So I doing an initiative to search about the information of our enemies so we can secure our win in this Holy Grail War!"
