Let's came back to the early morning in the times when Shirou shouted because of the change to his eyes.
"What happened to my eyes! Why did my pupils turn like a snake pupils!" Shirou was currently feeling angry, confused and astonished by what had happened to his eyes. He really didn't understand why his eyes could change like that.
'Shut up Archer!' Zelretch said. 'You just awakened a special ability that you inherited from a special genetic condition that belongs to another you in this dimension! Didn't I tell you about it before, if sooner or later the special ability of your current body will awaken, have you forgot about it?'
Ah, I completely forgot about that, but why has this special ability only awakened now?" Asked Shirou.
'That's because your body is considered mature enough to awaken those two eyes, a few days ago your body has gone through changes isn't it? You became more taller and your eyes color is also changes,' Zelretch replied. 'I think the changes in your eyes are the continuation of the previous changes, I think after the change in your eyes you will experience one more change and at that time, you can be considered an adult as a High human.'
"I have to undergo one more change!?" Shirou said. "How did you know that, Zelretch!"
'Aaaah why are you being so forgetful, Archer! Have you forgotten that now as a descendant of a High human you will have another abilities other than those two special eyes that can give you the ability to create super-real illusions? That's why I'm sure that you will undergo one more transformation and awaken at least one more special ability,' Zelretch said.
"Being a descendant of a High human is really troublesome, is this the little surprise that God told me earlier?" Shirou sighed, became an ordinary human is more than enough for him but right now in his second life his race already changes more than one, that was ridiculous for him.
'Maybe yes maybe no,' Zelretch said while grinning. 'You must find it by yourself what is the little surprised that God give to you.'
"Zelretch, you know something I didn't now, don't you?" Asked Shirou in a suspicious tone.
'Maybe,' Answered Zelretch. 'But I don't like to tell a spoilers! So I won't tell you anything even if you ask about the little surprise that God have for you.'
"At the time like this you still have a way to prank me," Shirou said who sounded annoyed when he spoke. "Heh, fine if you don't want to tell me! But what make me confused is the God said I will get a surprised when I arrived in this dimension, but till now I didn't think I got the surprised from Him at all."
'His perception of time is different from our,' Zelretch said. 'He maybe said 'soon' but that word can be means faster or slower, so don't doubt His word because I'm sure soon or later you will get the surprised that God will give to you.'
After Shirou finished washing his face, he then left his room and want to go to the kitchen to start preparing the breakfast but before he got to the kitchen Irisviel was already standing in front of his room with a serious face. Completely different from her usual nature which is carefree and ditzy.
"Mama why are you standing in front of my room with a serious face like that? Are there is something that you want to talk with me?" Asked Shirou who was wondering why Irisviel was standing in front of his room.
Irisviel didn't answer Shirou's question and instead looked into his eyes with a serious look, and before long she sighed and said:
"Misuzu's calculations are absolutely correct. Today is indeed the day you awaken Ban's illusion eyes, sigh."
"Ban?" When Shirou heard that name he thought back to the dream he had just had, the man in his dream also had the same name like the Irisviel has just said. 'The other me in the dream calling the man Ban as his father, are mama know something about that man?'
Before Shirou had the chance to ask Irisviel about Ban, Irisviel had already pulled him up while saying:
"Shirou since you already have the same eyes that your real father had, I have a lot of things to talk to with you. So now come with me!"
"Wait a minute, mama, what do you mean by the same eyes as my real father and what do you want to talk with me!?" Once again the scene in the dream popped into his head and Shirou this time could confirm and truly believe that the man named Ban in his dream was his real father and Irisviel's words is the proof.
"No need to ask too many questions! Now just come with me!" Irisviel pulled her body once more and led Shirou to one of the guest rooms in the Emiya Residence.

"Mama," Right now there were so many things that Shirou wanted to ask to Irisviel, especially about his biological parents in this second life, but he held back. Because Shirou knew the reason why Irisviel brought him to the living room is because she wanted to tell him about his biological parent. "What exactly do you want to talk with me?"
"Hmm where do I start? Ah that's right! Shirou can you remember what your life was when you were 6 years old?" Asked Irisviel.
"Not at all," Replied Shirou. "So why?"
Shirou once tried to do that because he can feel something has blocking the chikdhood memory of his new body, but in the end he couldn't access those memories the memories he had acces is only the memory of his new bodies from 7 years old year. Right when he was adopted by the Emiya family until the time the true owner of his nee body, died.
Shirou can feel the existence of a very strong seal that blocking the memories of his new body when he was 6 years old, even when Shirou tried to break the seal using Rule Breaker the seal he still couldn't break. Shirou could feels that the seal that block the memory on his head was made by someone from a higher dimension, so even Rule Breaker is useless.
"It's only natural that you couldn't access your memories when you were 6 years old, that was because your real father made a very strong seal inside your head so you can live a normal life," Irisviel said. "But slowly the seal will be gone and the memories of your past when you were 6 years old will return in the form of a dream."
'So that dream is my own memory that returning slowly,' Shirou said. 'No wonder I felt those dream felt so real!'
Who is my biological parent, mom?" Shirou said. "And why did my biological father have to seal away my memories?"
"Hmm, knowing the truth about your biological parent is your right as their child," Irisviel said. "Besides, I promised to Ban and Mizusu to tell you who your parents really are when you awakened those illusion eyes."
"Then, mom, can you tell me now?" Asked Shirou.
"Hmm, fine," Replied Irisviel. "We'll start with your mother first, Shirou do you know about Five Principal Clans?"
"Yeah I know the basic about them from Rin," Shirou said. "Five distinguished clan that purified and destroy evil spirit and youkai from ancient time in Japan, if I'm not wrong those five clan are Himejima, Shinra, Kushihashi, Doumon and Nakiri, they have a great power because their connection to the Shinto deity. Akeno-san Tsubaki fuku-kaichou is also from those clan. Don't tell me that my mother is from one of those clan."
"No, you're mother is not from one of Five Principal Clan," Irisviel said. "But she came from the clan that unite the Five Principal Clan from the background, your mother name is Kusakabe Mizusu. The heir of Kusakabe clan, the omnyouji clan that follow a Buddhism that have history far longer than the Five Principal Clan, a clan that have a demonic genes inside their blood that's why Kusakabe clan can have a magical aptitude more than the Five Clan. And that's also the reason why they can became the leader of Japan magical world."
