Educating naughty younger sisters

Nana was very upset.

Actually if it wasn't for her father's orders, her mother's persuasion, and her older sister who lived with Eiji Seiya. She didn't want to live in the same house as the man who became her eldest sister's fiance.

That man was very handsome, very pleasing to the eye, but she didn't want to admit it and didn't like it.

Why?

It was because from his inner voice all along, she knew her eldest sister's fiancé had many women.

He's a bastard!

Having other women besides her eldest sister!

Although in Deviluke things like polygamy or harems were legal, but because of her father, the King of Deviluke even only had her mother as his wife. Nana thinks a good man is a man like her father who is very loyal to her mother. A man who has more than one woman, more than one wife, has a harem, in her eyes that man is a bastard that she really dislikes.

Knowing that her eldest sister whom she loved and respected chose a man like Eiji Seiya as her fiancé, she was naturally unhappy and hostile towards him.

If possible, she wanted to persuade her eldest sister to break off the engagement with Eiji Seiya. Actually since she first came to earth this morning, she had persuaded her eldest sister, but the other party disagreed and kept saying that "Eiji is a very good person, you just don't know him well, Nana."

Something like that and she failed. Even so, she would not give up.

Nana will prove to her eldest sister that Eiji Seiya is not worthy of her.

"Nana, right? Can I call you that?"

"Hmph!"

The girl snorted instead of answering him properly, Eiji felt his head hurt a little just from dealing with a girl like Nana.

Unlike the Tsundere attributes of Yui and Mai, Nana's Tsundere attribute was the type that gave people a headache. Only a masochistic protagonist would really like this kind of girl.

Eiji felt he had to educate this girl so that she wouldn't be like in the original work because now she would live with him.

He had no intention of becoming a punching bag like Rito in the original work for the girl.

So he still had to do something troublesome.

"What did you say before? I definitely didn't say anything that could offend you, Nana."

"Hah! Eiji, you did not say anything, but you said it in..."

Nana wanted to say things about the inner voice, but her voice disappeared when she wanted to say that.

"Saying where? Nana, I didn't hear you clearly. Can you say it clearly?" Eiji smiled, he smiled amusedly at the sight of the girl embarrassing herself.

Nana who saw Eiji's smile clenched her fists, her face red with shame and annoyance!

"I told you! I know you said bad things about me in..."

She didn't finish her words again.

Because her voice disappeared again.

"Why?!"

Nana didn't understand, she really didn't understand why her voice always disappeared as if something prevented her from telling Eiji about his inner voice.

At this moment, she heard Eiji secretly laughing at her in his heart which made her even more upset.

[Hahaha! What's wrong with this girl? Is she actually pretending to be angry and wants to make joke? Pfft! The joke wasn't funny, but the face you're making right now makes me want to laugh!]

"Who's pretending? Eiji, stop making fun of me, you bastard!"

"Nana, where did I offend you? I didn't say anything. Is your hearing okay? I suspect you have a problem with your ears, want me to take you to the doctor?"

"Your ear is troubled! You're troubled! Ahhh! Why is Onee-sama engaged to a shitty man like you! You bastard who has many women!"

Nana glared at Eiji, she even bared her small fangs as if trying to intimidate him.

Eiji who saw this laughed. He could now slightly guess why Nana disliked him so much. It seemed to be related to the women in his harem.

Nana wanted to jump up and punch the annoying man in the face, but unfortunately her shoulder was grabbed by an hand.

"Ane-ue! Don't stop me! Let me--"

"Enough Nana. I already said not to be rude to Eiji. Didn't you hear me clearly? Eiji is my fiancé, you shouldn't call him a bastard either, okay?"

Lala was still smiling, but there was a seriousness in her tone that let Nana know that she had angered her eldest sister.

Nana's eyes were slightly wet, even though she only wanted to help her eldest sister not to be deceived by Eiji.

But instead of supporting her, her eldest sister scolded her.

Momo? Her younger sister didn't help either, the girl just watched it all while drinking tea.

"Well Lala, it's okay, you don't need to scold Nana."

To Nana's surprise, the man she hated was helping her.

"Is it true? But Nana is naughty, she keeps being rude to you."

"Hey~ it's okay. Isn't it natural that Nana doesn't like me because I have many women besides her older sister? She thinks I'm a bastard."

"No! Eiji is not bastard! I myself asked him to find more women to be my sisters."

"!!!" Nana and Momo were shocked.

They looked at their older sister, Lala and wondered if there was such a thing?

This was the first time they had heard of it!

Unlike Momo who just smiled as if she was thinking about something. Nana felt dazed, there was also a little guilt in her heart because she blamed Eiji. Even so, it didn't last long because Eiji didn't refuse her eldest sister's request to find more women.

Isn't that still a bastard? An unfaithful man is a bastard!

Nana wanted to say something, but before she did, Lala gave her a look that made her fall silent and dare not speak.

Although her eldest sister usually always acted childishly and rarely got angry, when she did, she knew it was the scariest thing. It was like watching a mother who was angry because her children were too naughty.

"....."

Seeing Nana finally shut up, Lala nodded in satisfaction, she then looked at Eiji with worry. "Eiji, I apologize for my little sister's actions."

Eiji shook his head. "No, you don't need to apologize Lala."

[It's not your fault anyway. If anyone should apologize. It's your naughty little sister. In the original work, Nana was hardly ever scolded at all when she continued to scold and beat up Rito.]

[A child will develop habits if they are never properly reprimanded. It's fine if the thing the child is doing is a good thing, but Nana is... I could see throughout the episodes of the anime, the girl's violent tendencies were getting crazier. Fortunately the only one who suffered from Nana's violence in the anime was the protagonist Rito].

[Rito, you're pathetic. I remember you're a regressor now, right? That means you've felt the beatings from Nana like in the original work? How did you survive? It's quite remarkable that you didn't become a masochist until now.]

"Does the sun rise from the west?"

Mikan who was studying at school wondered. She was used to hearing about the bad and miserable things her older brother had experienced in the original work so she wasn't surprised to learn that it was a girl named Nana who beat up her older brother.

But this was the first time she heard Eiji praising her older brother!

Speaking of her older brother, lately, he...

"Achoo!"

"Ah, is someone talking about me?"

Rito suddenly sneezed, he rubbed his nose with confusion.

He has been absent from school for almost a week.

Lately, especially today he kept focusing on practicing in his backyard in shorts without a top. The things he did were actually like exercising, doing push-ups, shit-ups, etc. to strengthen his bloodline and strangely it worked.

Something like this is obviously impossible for anyone else, but who made Rito the protagonist?

But unlike before where he would train hard in order to get revenge on Eiji for the umpteenth time, this time he wasn't, he was doing it for something else.

Staring up at the sky, his gaze actually penetrated the sky and saw the stars in space. Rito smiled as if the bad things he had experienced the previous few days were just that, for him those things had passed and he didn't care anymore.

Now he had a new goal that had nothing to do with Eiji.

It didn't even have anything to do with the women he loved in his previous life.

After being slapped many times and the womens he loved being taken away by Eiji, Rito realized something.

From the dramas that Mikan often watched, he took a sentence.

"Women only affect the speed of a man to draw a sword!"

He also added.

"I, Yuuki Rito, from now on will only focus on becoming strong and will one day become the Galactic King again like in my previous life!"

"Unlike in the previous life, this time I don't need the help of Lala and the others. I will do it alone with my power!"

"My enemies from my previous life, wait for me. I will slaughter you all!"

Back to Eiji.

Eiji didn't know that Rito had already had an epiphany like the protagonist in those novels.

Being constantly defeated by him and never winning even once, protagonist Rito gave up and didn't want to fight him again.

Unlike the protagonist Issei who is very stubborn. In his dictionary, Rito still has the word give up on the impossible and would rather move on to something else.

Lala who heard Eiji's inner voice, she understood something and looked at Nana who seemed to be able to hear the inner voice as well. Since Nana and Momo are also heroine, they should also be able to hear it.

That's why she looked at Nana as if telling her to do it.

"Ane-ue, w-what's wrong?"

"Nana, do it."

"No! There's no way I'm apologizing to Eiji!"

"Nana... Don't be naughty. Ane-ue doesn't want you to have the bad habit to not apologizing when you do wrong. Besides you and Momo want to live in Eiji's house, how could you have this kind of attitude towards the host?"

"But! But! I'm not..."

Nana wanted to curse Eiji. Damn it! If it wasn't for the man's inner voice saying the bad things she did in her original work, her eldest sister would definitely not discipline her like this!

Seeing that the man was also looking at her with a smile even though the smile was handsome, in her eyes it was a mocking smile that made her want to blast the man with her fists.

Do not underestimate her physical power as a Deviluke who inherited the blood of her father and mother. If she wanted, she could blow up this house with just her fists. Although from Eiji's inner voice all along she knew the man was very strong, she was also very confident in her power as the second princess of Deviluke!

It's just that he didn't expect this princess to be told to apologize. If it was someone else who told her, she would not want to, but unfortunately it was her eldest sister who was one of the people who could do it.

Nana glanced at Momo as if asking for her help with her gaze. 'Momo, help me!'

Unfortunately Momo only glanced at her and said with a smile. "Momo, what Onee-sama said is right. Eiji-san allowed us to live in his house, so your attitude towards him shouldn't be like that either."

"If Okaa-sama finds out you're doing this, she'll definitely discipline you harder than Onee-sama did."

Her younger sister was unreliable.

That girl was using her mother to threaten her instead of helping her!

Thinking of the last time her mother had disciplined her for mischief in the past, Nana shuddered and she knew that at least her eldest sister was gentler than her mother.

If she refused to apologize now, who knew her little sister wouldn't hesitate to call her mother.

Nana looked at Eiji sitting on the sofa casually, she bit her lip and said. "Sorry."

"What? I didn't hear you clearly. Nana, what are you saying?"

"You! You... There's no way you didn't hear! I've said it clearly!" Nana's flat chest rising and falling, she looked at Eiji angrily. She felt humiliated to be told to apologize like this, but right now her eldest sister was urging her again.

"Nana..." Lala sighed. Momo was fine, but her other sister was very troubled. It seemed that she had also failed as an older sister for spoiling her younger sister too much since childhood.

Seeing her eldest sister's sad look, Nana couldn't stand it and this time she said it out loud.

"Sorry! I was wrong! Eiji Seiya, I apologize for treating you too harshly! Can you forgive me?"

Nana was ready to be humiliated more by the man sitting in front of her, but the man nodded and said.

"Sure, it's just a small matter. I actually didn't mind it too much in the first place."

'Small problem? Nonsense! You're obviously very troubled with me! On the surface it's fine, but inside you're laughing at me! Ahhh! This man is so annoying! Wait, I won't give up making you look bad in front of Ane-ue!'

Nana secretly cursed in her heart, she certainly didn't apologize sincerely.

Lala was happy that Eiji forgave her younger sister.

As for Momo? The girl continued to stare at Eiji. No one knew what she was thinking at that moment.

Eiji was satisfied to make a brat like Nana apologize to him. Although he knew her apology was insincere, he was satisfied to see the humiliated expression on the girl's face.

This was a good day and it was just the beginning for Nana.

...

In Kuoh Gakuen, it is precisely in a passage where there is a room that is locked from the outside with many chains and magic padlocks.

The hallway was quite dark as it was located at the end of the left wing of the school.

The students and teachers are not allowed and forbidden to enter this hallway except...

Rias and her peerage, Koneko and Yuuto to be exact except Akeno who was absent from school today were standing in front of the door of that room.

"Buchou, what room is this?" Koneko asked curiously.

Yuuto was also looking at Rias curiously, after all he was also a first timer here.

Rias looked at her two peerage and said with a smile. "Ah you two I haven't told you yet. Actually before you two joined my peerage, after Akeno became my Queen, I also got my Bishop."

"Buchou, you mean, inside that room is one of us?" Yuuto immediately understood, but he still wanted to make sure.

Rias nodded. "Yes."

"But why is that person locked inside this room?" Koneko tilted her head in confusion.

Yuuto was also as confused as Koneko.

Seeing her two cute servants like this, Rias naturally told them the reason.

Her Bishop, named Gasper Vladi was one of Longinus' users, the Forbidden Balor View, also known as The Evil Eye that Stops the World. Like the name of his Sacred Gear, he could manipulate time like stopping time, but because his power was not uncontrollable, he was forced to seal it in this room.

Upon hearing this, Koneko and Yuuto were surprised and also amazed. Because why not? Unlike Koneko who didn't have Sacred Gear and only relied on her power as Nekoshou and Yuuto who used his Devil Sword.

This person named Gasper had one of Longinus' Sacred Gear!

Person like this...

He must be a cool character, right?

But when Rias waved her hand to automatically open all the chains and magic padlocks that locked the door.

*Click!*

The door opened, the two followed Rias into the room that looked...

"....." Koneko.

"....." Yuuto.

Looking at the room filled with items such as action figures, hanging women's clothes, posters of anime girls, game consoles and other things that smell like an otaku.

Their image of the cool Gasper in their minds naturally began to crumble.

"Gasper, it's been a long time. How are you?" Rias looked at the blanket protruding in front of the monitor displaying the game.

Koneko and Yuuto naturally glanced at the blanket that seemed to contain a person and they heard a feminine voice that seemed to have just woken up.

Wait, isn't Gasper a man? Why is his voice...

"This voice... Buchou? Are you visiting me?"

The blanket was pulled up, from Koneko and Yuuto's point of view.

They saw a girl in pajamas coming out of the blanket. She had platinum blonde hair and reddish purple eyes. Her hair was styled in a short bob cut with some small bangs on her forehead, and her ears were pointed.

Even Yuuto who was not particularly interested in women could not help saying: "Beautiful."

Gasper who saw the other two people behind Rias, he immediately got back into his blanket, and blushed at being called beautiful.

Rias looked at Yuuto strangely.

Yuuto scratched his cheek awkwardly. "Sorry, did I say something wrong?"

Rias shook her head.

"No, it's just that Gasper is a man. So don't be fooled by his appearance, okay?"

""Eh?""

Not only Yuuto, even Koneko dropped the dried fish snack she had brought from earlier.

They looked at Gasper who was hiding under the blanket with surprise on their faces.

"P-Please don't stare at me! Wahhh why are there so many people! Please ignore me!"

Gasper screamed in panic, he even started hiding behind the sofa which made Yuuto and Koneko confused.

They wondered what was wrong with that boy?

Rias smiled wryly.

"Besides liking to dress like a girl, Gasper is also a very shy person. Yuuto, Koneko, can you guys go wait outside for a while?"

"Ah... I see." Yuuto and Koneko said simultaneously and they nodded.

After the two left and there was only Rias and Gasper.

Gasper poked his head out slightly from behind the sofa and asked from a distance.

"B-Buchou, why are you suddenly visiting me?"

"Why not? Can't I come just to visit one of my cute servants?" Rias smiled and sat down on one of the sofas opposite Gasper.

"Ehhh! Sure, you can. But, but... Are you sure that's the only reason you came here, Buchou?"

Gasper couldn't believe it, if Rias hadn't persuaded him to go out and attend school like the rest of her peerage like she had on the last visit, he must have come for something else.

Rias sighed.

Although Gasper was shy, he was quite smart.

Of course there was a reason why she was visiting Gasper today and that reason was actually related to the Three Faction meeting that would be held in a few days from now.
