Shirou and all of his wives just arrived in a new dimension who become their new destination. But when they arrived in this new dimension, they did not expect that their appearance and body are regressing back to their teenager look. Shirou height was change from more than one hundred eighty six centimeters back to his one hundred and seventy two centimeters height that he have when he was fifteen years old. And for Shirou going back to his old height are disturbing him a bit, because his reach in fight will be dropped a bit.
Rin didn't look changing at all, because when she was in her twenties, she still look like whe she was in her teenage years so for her going back to be a teenager did not affect her so much, the same thing also happen to Sakura, she did look different except for her breast size who was much more smaller then when she was adult.
Illya are going back to her loli form, but her loli form are much more taller and sexier than her ten years old loli forms. So Illya feel a bit relieved that she was not going back to her kid form.
Arturia was still look the same in her petite body so there was no change for her much to her dismay.
Rider height are not changing at all but her breast size was smaller and her purple hair are shorter than usual.
All of them have a change without the reason they did not know, well except for Arturia of course because she is was as youthful as usual.

"We just arrived in a new dimension and we suddenly changing into a teenager again! Why we become like this! Ooi Shirou can you explain why we are like this?" Asked Rin while grabbing Shirou t-shirt.
"Rin, you are the one who have most brain among all of us, so if there was someone who have the answer that would be you. So why did you asking me for the answer?"
Shirou replied while sighing.
"Nee-san, Senpai was right. Among us the one who have the most knowlegde about magic are you and Illya and your knowledge even surpassing Illya because your geek nature so don't grab Senpai T-Shirt like that because you are angry."
Sakura who did not like the way Rin treating Shirou was repriminded her older sister that she was the best Magus between all of them to make her stop doing stupid thing to Shirou.
Rin faces become red because of the words that coming out of Sakura and Shirou mouth. She feel ashamed to herself because she totally forget that she was the best magus in her group.
Illya, Rider and also Arturia are trying their best tō not laugh. Because it was rare for a perfectionist like Rin doing a rookie mistake. And for them the mistake that Rin do was a hilarious thing to see.
Sakura and Shirou can only sighing when they saw see Rin reaction.

One hour later inside a very spacious hotel room, after Rin was doing some analize to the new dimension where they currently is. Rin still hasn't find the answer why they appearance are changing.
"The age of god of this dimension already passed, and the mana lingering in the air of this new dimension are really thin to the point almost non existence. And I still cannot found the the reason why all of us are changing back to our teenage form."
Rin are sighing, she really hate the situation where she did not know anythig. In Doraemon world she atleast knew a basic information about that world because she already watching Doraemon anime from when she was a little kid. But in this unknown new world she like an alien who just come to the Earth.
"So even the all knowing Tohsaka Rin didn't know the reason why we become younger, huh? What a shame!"
Illya who also collecting information in her own way by using internet are mocking Rin. Because she already knew what are the world they currently in, and she also had a feeling why they changing into a teenager again.
"Shut up you brat! Don't mocking me if you yourself hasn't found anything at all!"
Rin and Illya are having a respect to each other as a Magus and also as a part of Shirou harem. But the truth is they are a rival and have an unhealthy competition in a research as a magus.
***
"Sorry to make you feel disappointed Tohsaka but unlike you who are trying to search the information of this world by using old fashion way who was a bit unreliable. I already knew what kind of world we are in because of the information that I got from the internet."
Illya words making Rin feel angry but she was doing her best to hold back her anger because Rin realized a fight between her and Illya are only wasting time.
"Illya are you really know where we are right now?" Asked Shirou who was really curious about the world where they are right now because he cannot have the information he want by using the Structural Analysis.
"Of course Onii-chan! The world where we are right now was the world of Arifureta! A harem isekai novel world. With an otaku protagonist who will be summoned to the other world along with all of his classmate and homeroom teacher. And I think the reason why all of us going back to our teenage body because we must to enrolled in the protagonist school and get summoned to Isekai along with the protagonist. The level of the magic in the isekai where the protagonist will be summoned was not as high as our Magecraft but there are seven special magic in those isekai that I really want to have no matter what!"
Shirou never read Arifureta light novel, but he knew the basic information of Arifureta from the story that coming out of Illya mouth. And he also feel curious are he have the aptitude for the seven magic or not.

"The Second magic that I used was a modified version that Zelretch teach to me. And I think the modified version of Kaleidoscope also included a change in our appearance according to the world or dimension we will go," Shirou said while feel a bit angry to Zelretch because he can prank him even though he was not with him or close to him.
Rin can only sighing when she knew that her teacher in Second Magic are pranking them with the modified version of Kaleidoscope. She knew her Sensei was not a evil bastard. But his pranking nature not making him a good people her Sensei nature is more like a chaotic neutral rather than an evil or good. But one thing Rin knew about her Sensei is that Zelretch will never betray a humanity no matter what
"So we will become a highschooler again? That was troublesome. Because I already used to be a teacher for more than five years but I think this is a good chance to have a normal highschool life even if it only for a moment."
Sakura was a bit troubled when she was heard that she must to be a student in highschool for a second time. But she also happy because she can have a second chance to have an ordinary highschool life she dream off.
"Become a highschooler, huh? This would be interesting because I never had a chance to go to school. As a daughter of a king I was homeschooled so going the school will become a new experience for me."
***
Arturia was never had a chance to go to school because of her status. So she is really interested to go to school along with Shirou and the other.
"Going to school was okay, but we need to do a lot of preparation before that like forging a new identity, making an account at bank and a lot of troublesome thing. We even need to change our apperance so one of us can act as an adult to taking care of the paperwork."
Shirou was never like doing a paperwork, because in middle school to High school he was forced to do the paperwork of Fujimura estate by Taiga. And for Shirou doing a paperwork was the most tortured thing to do in the world.
"I and Sakura will taking care of it, so Shirou you don't have to worry about it that much. Because I knew how much you hate in doing a paperwork because of Fujimura-Sensei. But I want you to give me a lot of money you keep inside the Gate of Babylon because to make a fake identity and buying a house for our homebase a lot of money was needed. And please don't be stingy in giving me a money or you will regret for being stingy with me."
