(First, a place to leave your brain: All characters in this book are of legal age. The content of this book is positive, sunny, and uplifting, with absolutely no harmful influences. Additionally, in this book's setting, the titles "brother" and "sister" between Wise and Belle are just terms of address; they have no actual blood relationship. Okay, this is the author speaking after the second review. To get it approved, I changed most of the terms of address as well.)
"Brother, come help me move this. It's too heavy, I can't lift it."
A girl with deep blue hair waved and called out to a young man with grayish-white hair not far away.
"I know, Belle. I'm coming," the young man replied. After placing the videotape in his hand onto the shelf, he turned and walked over to Belle, then easily picked up the box of tapes from the floor.
"Wow, you're so strong, brother!"
"Alright, even if you praise me like that, you're still not allowed to have any more ice cream today."
"Hmph, you're so stingy, brother."
"Come on, this has nothing to do with being stingy."
After saying this, he carried the box into the room. Hearing his words, Belle puffed up her rosy cheeks in a pout and slowly followed him.
"Mmm-hmm, mmm-hmm (Eating too much ice cream will give you a stomachache)," a small, rabbit-like creature, black and white in color with an orange scarf marked with the number '01', chimed in with its unique language as it walked over.
"See? Even Eous knows it," Wise said.
"Hmph, I won't get a stomachache."
"It'll be too late for regrets when it happens. And if I remember correctly, your 'time of the month' is coming soon. Don't come crying to me when the cramps start."
"You're a mean brother! I'm not talking to you anymore!" Belle's face flushed slightly as she finished speaking, and she ran out of the room to help No. 18 stock the newly arrived videotapes.
"Really... Oh, whatever."
Watching his sister run out, the young man shook his head helplessly. His name was Wise, and he had been in this world for over twenty years.
That's right, he wasn't originally from this world. In his past life, he was at home logging into Zenless Zone Zero, getting ready to clear his dailies, when a white light flashed.
When he woke up again, he found himself as a baby in swaddling clothes, and then he lost consciousness once more.
Due to some unforeseen events, he met Belle at a very young age in the same orphanage. Later, they met their Teacher, though subsequent events led to their Teacher leaving them.
(In my memory, I used the term 'Master', but a reader said it was 'Teacher'. I thought about it, and it seemed right, so I changed it.)
But at least he and Belle were together, and that was enough.
As for why the story starts today? It wasn't because it was a particularly special day, but because…
Wise looked at the virtual screen in front of him. It was something he'd had since he was born in this world, something you could call a System. The most speechless thing about this system, however, was its incredibly long activation time. For the past twenty-odd years, he hadn't received any help from it at all.
But thankfully, the system's unlock countdown was finally ending today.
It's made me wait for over a decade, and it's finally activating? Today, I'll see just what kind of power you have, a system whose name I can't even see clearly, with nothing but a panel and a countdown timer.
He went to his room. As the countdown ended, Wise clicked "Activate" without hesitation. There were no startup animations or special effects.
With a mechanical whir, the panel automatically upgraded. All the system's functions and instructions materialized into a user manual before his eyes.
"This... this isn't right, is it? This is..."
[Supreme Succubus System]
Host: Wise
Charm: 88 (Considered to be on the higher end of charm among humans.)
Current Charm Influence: Can increase the favorability of those you meet for the first time (this effect is doubled on the opposite sex).
"This... isn't this supposed to be a proper game? It's only rated 16+, why would a system like this appear?"
Wise didn't understand, but soon, something even more baffling appeared.
[Current Favorable Females:]
Name: Belle
Charm: 95
Identity: Host's Younger Sister (?)
Favorability: 100+
Note: The host can obtain rewards by triggering emotional fluctuations in subjects with high favorability. The higher the favorability, the richer the rewards.
Evaluation: She holds an extremely high degree of favorability towards you, the host. However, the system cannot evaluate whether this is based on familial affection.
Inner Thoughts:Wise is so mean. I'm not a kid anymore, I just want one more ice cream, what's wrong with that? But... he even remembers my period so clearly. He cares about me so much, it's so embarrassing, hehe.
The high favorability makes sense, but what's with that evaluation?
System, don't just spout nonsense. Be careful, or I'll sue you for slander.
The system ignored Wise's rebuttal and silently presented a Newbie Gift Pack.
[As compensation for the system's delayed arrival, a Newbie Gift Pack is presented to the host.]
Wise chose to open it without a second thought.
[Newbie Gift Pack opened. Congratulations, Host, for obtaining the Talent Ability: Beauty is Justice (S), and 12 Charm Attribute Points.]
Beauty is Justice (S): 80% of the host's Charm will be added to their other attributes. After all, one must have strength to decide what is justice.
The talent's description was simple and direct, which was fine. As for the 12 Charm points, adding them to his original score brought him to a perfect 100.
Did the system calculate this? It's a perfect score, right on the mark.
Wise thought to himself. This so-called Supreme Succubus System didn't seem as indecent as he had imagined. Let's add the points and see what happens.
Wise then allocated all 12 points to Charm, bringing the value to 100.
"Hmm, I don't feel much different. But the bonus from 'Beauty is Justice' is pretty obvious."
Wise clenched his fist. The box that had required some effort to lift just a moment ago could now be picked up easily with one hand.
"Brother, I've finished arranging the shelves outsi—"
"Belle, why did you come in again without knocking? But you're just in time. Take a look, do you see any changes in me?"
Wise felt a bit exasperated as Belle suddenly pushed the door open. He had reminded her so many times to knock before entering someone's room, but his sister never listened.
However, Belle didn't answer his question right away. She froze on the spot, her voice stuttering.
"Uh, th-that is, I suddenly remembered I forgot to charge Eous. I'm going back to my room now."
After saying this, Belle immediately turned and left, giving Wise no chance to ask anything further.
But the sharp-eyed Wise noticed that as she left, her face was incredibly red, like that of a shy young girl. Which, to be fair, she was.
"What was that all about?"
Wise didn't understand the reason. It was clear he had no concept of what 100 points in Charm truly meant.
