Type-Moon, isn't this really the other world?

Aoi Tohsaka felt as if two versions of herself—an angel and a demon—appeared in her mind.

Devil Tohsaka Aoi: "It's alright. You're just trying it out. It won't wake him up. Besides, you've already taken him in and given this homeless man such a good life. It's not a problem to secretly take a little reward, is it?"

"As for Tokiomi Tohsaka, putting aside the fact that he was the one who rejected you, you are also an ordinary woman with your own needs and desires."

"You're not dealing with a man right now, so it's not considered betrayal."

Aoi Tohsaka: "Yeah, yeah!"

Since everyone thinks that way.

Aoi Tohsaka took a trembling deep breath and resolutely stepped into the abyss of sin.

······

[Ding! Congratulations, host! You have successfully put "Tohsaka Aoi" into the "Elementary Fall" state. You have received the reward "Basic Magical Knowledge".]

Lin Jiu'an opened his eyes groggily.

Looking at the system panel that suddenly popped up in front of him, Lin Jiu'an was deeply confused.

I didn't do anything!

Although not human.

But Lin Jiu'an wouldn't go so far as to harm Tohsaka Aoi, who adopted him and gave him tenderness and care like a mother.

Even Lin Jiu'an intended to do everything in his power to protect Aoi, Rin, and Sakura to prevent the later tragedy of the Tohsaka family. How could he possibly harm Tohsaka Aoi?

gradually.

Having regained some consciousness, Lin Jiu'an suddenly saw something fluctuating behind the system panel. Upon closer inspection, Lin Jiu'an instantly snapped back to reality, his eyes filled with shock.

"Mrs. Tohsaka?"

"Um, Jiu... Jiu'an, why are you awake?"

Aoi Tohsaka kept shaking her head, her long, jet-black hair swaying wildly.

She wanted to stop, but she couldn't stop anymore.

"you you..."

Is this how you take care of me?!

Am I the Sixth Beast, or are you the Sixth Beast?

······

As the eldest daughter and heir of the Tohsaka family, Rin Tohsaka is very strict with herself.

It's just dawn.

Rin Tohsaka had already gotten up and was exercising and practicing magic in the yard. By the time the sun had fully risen, Rin's face was covered in sweat, and she returned to the house satisfied.

Passing by the living room, looking at the empty and quiet space, a hint of doubt flashed in Rin Tohsaka's eyes.

"Where's mother?"

As is her usual routine, Aoi Tohsaka would already be in the living room preparing breakfast at this time.

Every day she would greet her mother here, then go upstairs to take a shower, and by the time she came downstairs, her mother would have already prepared breakfast.

But today, the living room is empty, and there is no sign of my mother at all.

"Still not up?"

"Do you have a cold?"

Rin Tohsaka went upstairs out of curiosity, intending to take a look at her mother's room.

But as he passed by Lin Jiu'an's room, he inadvertently heard voices coming from inside.

The voice was indistinct, and Rin Tohsaka couldn't hear it clearly, but it seemed that one of the voices was her mother's.

But why was his mother in his room so early in the morning?

Before Rin Tohsaka could listen carefully, Lin Jiu'an's side was suddenly opened.

"cold?"

Tohsaka Aoi looked at her daughter standing at the door in surprise, then a look of panic flashed across her face.

Is she really the mother?

Young Rin Tohsaka didn't notice her mother's panic; she was simply curious why her mother was here so early in the morning.

"Mother, what are you doing in his room?"

"Yes, because we were worried that Jiu'an might not be used to our home yet, my mother stayed with him last night."

Upon hearing this, Rin Tohsaka couldn't help but show a hint of envy.

It turns out to be the legendary sleeping with one's mother!

As daughters of the Tohsaka family, Tokiomi Tohsaka imposed the strictest requirements on them. Since they could remember, neither she nor Sakura had ever slept with their mother, even though Rin Tohsaka considered herself a little adult and could fall asleep without an adult's company.

But Rin still really wants to sleep with her mother!

But this first experience, which none of these mothers' own daughters had ever had, was taken away by this boy who had only arrived at their home yesterday.

Looking at the boy behind the mother, who was not even as tall as herself, Rin Tohsaka felt jealousy for the first time in her life.

But then.

Rin Tohsaka was drawn to her mother's walking posture.

Why does my mother walk with a limp?

······

Chapter Four: It's all Tokiomi's fault!

Rin Tohsaka went back to her room to take a shower.

Aoi Tohsaka went downstairs to make breakfast.

Lin Jiu'an, now alone, sat on the edge of the bed, looking at the name Tohsaka Aoi on his system panel.

"Although the process and the goal were wrong, at least I had my first 'goal'."

Lin Jiu'an was somewhat saddened.

Even though she never intended to infiltrate the Tohsaka family when she came to Fuyuki, and never intended to take down Tohsaka Aoi after she entered the Tohsaka family.

Is this what they mean by "the process is all wrong, but the result is all right"?

No matter how.

Since things have already happened, the reward shouldn't be forfeited just because of the regret of a sage's descendants.

Aoi Tohsaka's initial reward for her fall from grace was common sense about magic.

Although it's just (the basics).

However, as he collected the rewards, Lin Jiu'an could clearly feel that a lot of basic magician knowledge had been added to his mind, including the principles of magic and the basics of performing magic, as well as hundreds of basic magic tricks that are universal to magicians.

"The results were better than expected?"

Lin Jiu'an was never one to dwell on the past.

Now that it’s done.

Even if it wasn't my intention, I can only go with the flow.

only...

"How can we prevent Tokiomi from finding out?"

Just as Lin Jiu'an was pondering.

Suddenly I felt a light poke on the back of my hand.

The wicked little imp, who was contemplating something bad, was startled. His body trembled violently from overreaction, causing the girl next to him to scream "Ah!"

Lin Jiu'an looked closely and saw that Tohsaka Sakura was sitting on the ground with a pained expression on her face.

Clearly, Lin Jiu'an's reaction had taken her by surprise, startling her so much that she fell to the ground and hurt her bottom.

"Are you okay?"

Lin Jiu'an hurriedly jumped off the bed and helped Tohsaka Sakura up.

"Sorry, I was thinking about something just now. Did I scare you?"

With deep regret.

Lin Jiu'an was completely unaware of how attractive his human boyish face, transformed from the Sixth Beast, was to females.

Looking into Lin Jiu'an's close, apologetic black gem-like eyes and his flawless, boyish face, Tohsaka Sakura lowered her head, her long eyelashes trembling, her face flushed with shyness, and even her small earlobes turned bright red.

"N-It's okay, Onii-chan."

Lin Jiu'an was taken aback by the girl's soft and sweet "Onii-chan".

"What did you call me?"

"Onii-chan?"

Sakura Tohsaka looked up blankly, but then lowered her head shyly when she saw Lin Jiu'an's face so close to hers.

Speaks softly and sweetly, "Mom said that Onii-chan will be Sakura and my sister's family from now on, so Sakura thinks she should call him Onii-chan. Did Sakura...did she do something wrong?"

Looking at the pitiful appearance of young Tohsaka Sakura, Lin Jiu'an felt his heart almost melt.

Decided!

Since I ended up sleeping with Aoi Tohsaka without really knowing what was going on...

Tokiomi Tohsaka, as a father, is unable to fulfill his responsibilities.

Then I'll be the dad from now on!

"no problem."

Lin Jiu'an smiled and reached out to stroke Tohsaka Sakura's soft, short black hair.

"From now on, I'll be Sakura's brother (father)."

······

No matter how excited I am, I still have to face the problems that need to be faced.

Sakura came to call Lin Jiu'an to come downstairs for dinner.

Now, Lin Jiu'an sat at the dining table, glanced silently at Tohsaka Tokiomi who was sitting in the main seat, and then lowered his head.

Last night was so exciting, and this morning is so nerve-wracking.

He is currently just a "beast" that is not even in its juvenile stage. The forced severing of his connection with the Greater Grail has left him in an extremely weak state. Logically speaking, someone with his strength should continue to develop in his mother's placenta and is no match for Tokiomi Tohsaka.

If the other party finds out he slept with his wife...

"hiss."

"Kuan, what's wrong?" Tohsaka Aoi asked with concern and worry.

"It's nothing, I just bit my tongue."

Honey, could you please not be so concerned about me in front of your husband?

Lin Jiu'an, with the soul of an adult in his small body, nervously stole a glance at Tohsaka Tokiomi, only to find that he had only looked up at him once before continuing to eat, seemingly lost in thought.

The Tohsaka family's dining table was quiet, with only the sound of chopsticks and bowls being moved.

But Lin Jiu'an sensed an undercurrent of tension.

First up is Tokiomi Tohsaka, the man who was just cheated on by him last night. Who knows what he's thinking right now?

Next, let's talk about Rin Tohsaka.

The girl who discovered Mrs. Tohsaka's leg was 'limping' that morning kept looking up at Lin Jiu'an with a rather hostile gaze.

Finally, there's Sakura Tohsaka.
