Tosaka Sakura, no, it should be said to be Kiriku Sakura now.

This young girl with black hair and blue eyes was born in the Tosaka clan, a famous demon family, and has a magic circuit that is not inferior to her sister Rin. However, because the magic seal, the most precious inheritance of the magician family, which is the brainchild of the heads of the family, can only be passed on to one heir, the young Sakura is unable to obtain the knowledge and research results of her father, Tosaka Tokitomi.

For the magicians of this world, the magic circuit is a gift from the heavens, which can draw magic from the outside world (the Great Source) and transform it into magic that humans can use (the Small Source). If a person does not have a magic circuit, then he cannot generate mana. And if a magician has a lot of circuits, his total mana, recovery speed, and spell resistance will be much higher than average.

After a child is born, his magic circuit is finalized and basically does not increase due to acquired factors. Generally speaking, the better the parents' magic skills, the more magic circuits the child will be born. Therefore, the magician family pays great attention to eugenics, and even if they can't get a partner who is also a magician, they have to find a marriage partner with excellent blood among ordinary people.

Sakura's mother, Aoi Tosaka, is such a woman.

The Chancheng family, where there used to be powerful magicians, is now an ordinary family that has nothing to do with magic, but the magic factor in their blood has not disappeared. If you just look at the number of magic circuits, Aoi Tosaka is not far behind her husband Shichen, and the daughter born to the two is even more blue.

In this world, most magicians have only one attribute, and Tosaka Tokitomi is one of those people. A magician with dual attributes can be called a genius in the entire magician society.

However, compared to ordinary people, the talents of the Tosaka sisters are beyond the norm. Sister Rin not only occupies all the five attributes of earth, water, wind, fire, and air, but also has a full seventy magic circuits, and her younger sister Sakura even presents a virtual attribute that surpasses the plane! The qualifications of these two people are simply a miracle given by God!

Tosaka is proud of his daughter's excellence, but he is worried about Sakura's future. The secret techniques of the Tosaka family can only be passed on to one child, which means that there is a high chance that the other person will be reduced to mediocrity.

For the proud Shichen, mediocrity is a terrible thing than death. If Sakura doesn't have a talent for magic, then forget it, and let her live with Aoi in the world of ordinary people. However, this kid has excellent qualifications no less than Rin, which makes Tosaka Shichen very distressed.

Except for personally devoting oneself to the Demon Dao and cultivating, there is no other way to hide the demonic nature of the bloodline. If the Magicians' Guild found out about Sakura's existence, they would have soaked her in formalin as a specimen in the name of protection.

At this moment, the head of the Jian Tong clan, Dirty Yan, made a request to adopt Sakura, and Shi Chen was almost stunned by this surprise that fell from the sky.

Since coming to Fuyuki City, the bloodline of the Maki clan has been declining, and now they can't even find a decent heir. Desperate, the Dirty Inkstone had no choice but to ask for help from his allies, hoping to adopt Sakura and let her pass on the magic of the Kiriri clan.

In order to give his daughter a chance to display her talents, Tosaka Tokitomi sent Sakura to the Makiri family. From a father's point of view, Shi Chen, who hopes that his beloved daughter can have a happy future, is not wrong. Even if Rin and Sakura go on a hostile path in the future, it would be better than being captured by the Magicians Association as experimental materials.

However, the clumsy father did not think about how unsettling it would be for a five-year-old girl to leave her parents and live in an unfamiliar environment.

On her first day at Makiri's house, Sakura was taken to a dark basement by a dirty inkstone.

It was a small, bald, hunchbacked old man, his limbs had withered to the point where one could mistake him for a mummy, but beneath the sunken sockets were a pair of sparkling eyes. From the eyes that contain a strong will, you can vaguely see the demeanor of his youth.

"Let's go in, Sakura-chan. ”

Hearing the voice full of gloomy aura, Sakura didn't dare to resist, and could only walk into a strange magic array with an uneasy mood.

"Grandpa......"

"Don't be afraid, Sakura-chan. It's going to be over soon. The dirty inkstone showed a happy expression. And in the eyes of Sakura Makiri, that smile was too terrifying.

"Yikes!"

A large number of bugs emerged from all corners, and Sakura screamed in horror.

"Jiji, as a child of the Matong family, how can you be afraid of the imprint worm?"

Sakura's attributes are not suitable for the magic of the Maki family, so the dirty inkstone is ready to transform her body. To the old magician, Sakura was just a tool.

"Help, save Sakura...... Mom and Dad...... Save Sakura......"

The insects approached step by step, and Sakura's mind was completely eroded by fear, and she cried out desperately, "Who will save me!!"

"Accept your fate, Sakura-chan. Even if you shout for help......"

Before he could finish his words, a strong gust of wind appeared around Sakura, blowing away all the insects in the vicinity.

The next moment, the magic array under Sakura's feet moved, and the lines were broken up and reorganized, and finally turned into a new magic array.

"How is that possible?!this, this is ......" Of course, Kiriki Dirty Yan recognized this magic array, but he didn't understand why things had turned out the way they did.

"The magic array set up by the old man...... It turned out to be ...... What the hell is going on?"

Jian Tong knocked on the floor with a cane, but there was no impatient look in his eyes. There was no limit to the mystery of the world, and he never thought he was in control.

The reconstructed magic array glowed brightly, and a young man in a magic robe walked out.

As soon as Reilly stepped out of the space-time portal, he was imprinted by the rules of this world and signed a contract with the young girl in front of him.

Sakura looked up and looked at Reilly with tears in her eyes. That pitiful look, as if to say, "Please hug me".

Reilly touched the girl's head and said, "So, you're my Master?" he thought quickly in his mind, but he couldn't remember who the girl in front of him was. There is no such young Master in the plot of "Fate/staynight", even Illya, who looks like a child, is actually eighteen years old.

"Hehe, what an unexpected surprise. The Servant had overwhelming magical powers, and if he was willing to cooperate with him, it would not be impossible to capture the Holy Grail!

Seeing this old man, Reilly breathed a sigh of relief, the situation was not completely out of control.

"This gentleman is a magician, right? Do you have anything to do with my master?" Although he knew the identity of the old man, Reilly was not going to tell him.

"The old man is Sakura-chan's grandfather, and he is also your strong backing in the Holy Grail War. Jian Tong said with a smile.

"So, why would you do this to Sakura?" asked Reilly, pointing to the bugs around him.

"Hehe, don't you want your master to be stronger?"

"There are many ways to become stronger, and you don't have to do it. Reilly touched Sakura's head again and said, "Sakura, do you have any wishes?"

"Wish?" Sakura said with a look of hope in her eyes, "I want to play with my sister." ”

"Then, let my brother take you to her. ”
