Ye Han felt satisfied with his creation as he looks in front of him a growing tree, he gives himself a pat on the back as he removed the system of magic in the universe. He teleported to his mansion inside the Absolute Immortal Spirit Realm, only to see Ada teaching them basic knowledge of elementary to high school which they fluently absorb like geniuses. He didn't disturb them as he still had to manipulate the japan's system and create a birth certificate, ID and etc, he didn't forget to create multiple modern clothing that was the sizes of his daughters and his wife.
Lastly, he didn't forget to remove his fake face and reveal his devilishly handsome face before starting his operation. He left his wife and daughter's clothing in the living room so they could choose which to wear as he made like a hundred design base on his imagination. Ye Han began his operation by creating a portal below his feet and above the Tohsaka mansion, it was a very dark night as all of the elders and masters of the magus families were discussing the nonexistent mana and lost of their powers. Ye Han was falling like a fast bullet before he reaches the ground, he began to float.
The guards of the mansion didn't notice him as he was covered in dark clothing, he sneakily hands chop them in the neck as the guards outside each faint without letting the master of the mansion know the breakthrough. He entered the 2nd floor's bathroom window and saw the lights were turned off, Ye Han grin as he felt that he was getting better in sneaking in. But suddenly someone opened the door which made Ye Han curse in his mind and jumps onto the ceiling as the bathroom was regular room size and had a tall ceiling, he began to crawl like spiderman and went to the ceiling of the door. He saw a little brown hair girl planning to take a pee, so he quickly crawls out from the top of the door. Luckily for Ye Han, she was too focused on wanting to pee so he was unnoticed.
He sighed in relief as he slowly went to the meeting room which was on the other side of the mansion, he could hear the elders including Sakura's father talking about the loss of magic ability and the hope that the grail war still exists. He knocks on the door and let nature takes its place. The moment one of the guards open the door from the inside, he began to use his mind control ability and started to modify the guard's memories. The guards fainted as Tokiomi Tohsaka looks at Ye Han and said
"Who are you?"
Ye Han didn't start a conversation as he began to manipulate their minds. He deleted the existence of Sakura Tohsaka in their memories as he continue to read their mind like a movie, Aoi Tohsaka was in the bedroom caressing sakura's hair as she continues to believe that their decision was the correct one. While Ye Han was doing his operation, Rin opened the door to sakura's room and spoke to her mother.
"Mom, does sister really have to go?"
"Yes, my dear. It has been decided by the family....."
Rin just silently accompanied her mother who was caressing sakura's hair, meanwhile, Ye Han just finished his mind manipulation operation and began to walk towards sakura's room to which he felt two more living entities inside the room. He already memorizes who was inside the mansion so he knocks on the door which Tokiomi would most likely do. Aoi opened the door and saw Ye Han's eyes which were glowing red. Ye Han only said one word
"Sleep"
Aoi fell to the ground as Rin began to cautiously guard her sister and spoke in an impatient manner
"Who are you? and what are you doing in my families's property?!"
Ye Han smiled as Rin cautiously stares at Ye Han's face, she was feeling a weird emotion for a kid which made her heart speed up. Ye Han only put a finger in his mouth which expresses the word "quiet", he carefully moves Aoi to a rocking chair and caresses Rin's hair. Ye Han sighed as if they only think like a regular normal family, this wouldn't happen. He looks at Rin's eyes and said
"Sleep"
Rin slept on the side of sakura as Ye Han began to manipulate their memories and deleted the existence of sakura in their mind, while he manipulated the cute sleeping sakura's mind and change her memories and turned it like she was an orphan who runned away from her orphanage. A lot of people would probably think of Ye Han as an evil monster and he wouldn't deny that as he already made havoc in this universe which possibly killed a lot of good and bad people who were using magic like fighting and then their magic didn't work which made them lose because the other guy had a gun and shot them in the face.
But the concept of good and bad had already been broken the moment Ye Han attained knowledge of a lot of universes. Ye Han only believed in one concept which was "I do whatever I want and nothing will stop me", he carried sakura and left the mansion before they wake up. The next operation for him was an assassination of a specific bug user.
