Inner Voice: All Heroines Hear My Inner Voice

Everyone looked at the magical girl flatly.

Only Sona was massaging her forehead as if she had a headache.

She knew her older sister was very attached to her, or rather overprotective and fond of her since childhood.

Her sister's liking for her, she knew it was at a rather abnormal level.

Older sister's orientation was a bit wrong.

But unlike her older sister, her orientation was normal!

Sona simply cannot look at her own older sister with a romantic gaze.

No way, the other party is her sister after all!

And she wouldn't be romantically interested in other women either!

She only likes men!

After waiting for so many years.

There was finally a man around her age who was handsome, strong, and smart enough to beat her in a game of chess.

She didn't realize it at first, but after following him so far and hearing his inner voice.

She was getting more and more interested and now she was sure she had fallen in love with Eiji.

She didn't even mind sharing Eiji with Lala.

After all it was natural for a handsome and strong man to have many women.

In the underworld, it was not uncommon for nobles or strong men to have harems.

Everything was going smoothly.

She had told Eiji about their engagement.

Lala had agreed to the idea of sharing a man with her.

She just needed confirmation that Eiji was truly willing to accept her as his woman.

But her older sister couldn't let anything good happen, especially in front of her eyes.

Her older sister was adamantly against her and Eiji being together, even using excuses like getting her permission first by beating her in a duel.

Her older sister's power was unquestionable.

As one of the Maou in the underworld, her power was certainly very strong.

Although she did not know for sure, but many people in the underworld knew how powerful her older sister was as one of the devils who had contributed the most to the war in the past.

Because of her achievements in the war, she was recognized as one of the Maou who bore the surname Leviathan. From then on, Serafall Sitri's name changed to Serafall Leviathan.

Although her older sister was still part of the Sitri family, but she also had a separate status that was arguably higher than the Sitri family as a Leviathan.

But putting that aside, as her younger sister.

Sona knew very well what her older sister was planning right now.

Because her older sister was very confident in her power, she must have deliberately wanted to prove whether or not Eiji was worthy of marrying her younger sister by defeating her in a duel.

That was clearly unfair!

After all, her older sister was an ultimate class demon!

Although she knew Eiji was also strong, but compared to her older sister... maybe he couldn't...

"Onee-sama! You can't duel with Eiji now!"

"Oh, why can't I, Sona-chan?"

Serafall looked at her younger sister with a frown.

My cute little sister keeps defending a man!

Onee-sama is so jealous!

"Yes, that's because..." Sona thought hard, then widened her eyes and said: "Eiji just finished fighting earlier. He must be tired and it's unfair if Onee-sama is just as eager to duel him now."

"Besides, can Onee-sama sama stop with that duel idea? Eiji has already beaten me in chess, so he..."

"No! Onee-sama still has to test him herself! Is he strong enough to protect Sona-chan by defeating me? If he can't."

"Forget this matter of engagement or marriage."

Serafall became more stubborn, it seemed that defeating her was the only way that she wouldn't mind Sona becoming Eiji's woman.

"Onee-sama..."

Sona knew, after coming this far, her older sister was in a condition that could not be persuaded.

She looked at Eiji sadly, she was also actually not sure if Eiji even liked her and was willing to duel with her sister for her approval?

Eiji saw Sona's unsure look and knew the girl seemed to doubt whether he liked her or not.

Seeing Serafall also began to look at him with a Magical Girl pose ready to fight against the Demon King who wanted to kidnap her younger sister.

Wait, who is the Demon King who wants to kidnap your younger sister?

Me?

Eiji's lips twitched.

"So I have to get Sona's older sister's approval to be able to marry Sona? Is that right?"

"Yes! Eiji-chan! You have to beat me first if you want to get Sona!"

"Eiji-chan?"

"Yes Eiji-chan! Do you dare to duel with me? Let me tell you, I'm very strong and I can also blow up this forest as much as you do."

Serafall put her hands on her waist and placed one hand on her chest proudly.

With her Magical Girl cosplay, she looks even cuter.

"Eiji, if you don't want to. You don't really need to..."

Sona looked worried and hesitant.

Eiji looked at the girl with a smile and said, "How could I not want to? If I can get Sona Senpai as my woman. Isn't that too good to pass up?"

"E-Eh, you, are you okay with that? Do you like me?"

Sona's eyes widened, she looked at him with an expectant and slightly nervous look in her violet eyes.

The voice when she asked was even very small, especially in the last part.

Eiji nodded lightly.

"Although not as much as Lala. I like you and I'm sure it's only a matter of time before I like you more, right?"

[Sona was very beautiful. As a man who has even gotten permission from his first fiancée. How could I refuse another beautiful woman who offered herself to be my woman? Besides, Sona is a good girl, she's different from the green tea bitch].

[Such a girl, of course I'm greedy for her.]

Sona blushed, although she was a bit jealous that Eiji liked Lala more.

But she felt that it made sense.

After all, Lala had been with Eiji earlier than her. And Eiji had honestly admitted that he at least liked her and was greedy for her.

Although that liking might be more inclined to her beautiful appearance, but it was also a part of her.

Who doesn't like beautiful women and who doesn't like handsome men?

Sona actually feels more confident with her appearance now.

In the future, she just needed to make an effort for Eiji to like her more.

Yes!

The most important thing now is that Eiji accepts me as his woman and he doesn't reject me!

Without realizing it, her smile looked even sweeter than usual.

Making the other girls except Lala dumbfounded and sour.

They felt like they were being fed dog food.

Earlier the issue of people wanting to duel.

Now it suddenly changed again to a confession scene of a man and a woman.

They keep being forced to watch all this in one day!

Rias felt envious of Sona, she clenched her fists and wondered if there was still a chance to make Eiji join her peerage?

At least is it still possible to seduce Eiji and get a favor from him?

Akeno looked back and forth at Eiji, Lala, and Sona.

In her mind, she was actually imagining a lewd scene where Eiji fucked her and had a secret relationship with her while he already had two wives.

That infidelity scene somehow excited her.

She held her cheeks with both hands and a slightly red face.

"...Akeno, what's wrong with you?" Tsubaki who noticed the girl's strangeness asked.

"I-It's okay, Tsubaki. I'm fine." Akeno said before smiling again as usual.

Tsubaki couldn't believe it.

Having known Akeno for years, she knew the girl was actually rather perverted as a girl and had strange fetishes.

She must have been thinking lewd thoughts while looking at Eiji and the others!

As for her? Tsubaki was glad her king looked happy and wondered if Sona became Eiji's woman and married him.

Would she also automatically be considered Eiji's concubine or something?

Thinking of this, she was a little dazed.

Serafall had a complicated expression in her eyes.

She was happy to see Sona looking happy, but she was also unhappy that it was not her who made her younger sister look like that.

It was someone else.

Eiji Seiya.

This boy, he does like her younger sister. But his liking is nothing compared to her!

He's greedy for younger her sister's body!

He still likes other girls more than her sister!

How dare that boy make her sister number two!

And Sona-chan, why do you look happy about it?

You're too humble!

If you knew that boy's inner voice, I'm sure you'd be scolding him right now.

Serafall didn't know her younger sister could also hear the inner voice of Eiji and even the other protagonists.

She felt she was the only one who could hear that inner voice.

She was about to say what Eiji was thinking to her younger sister, but just as she was about to do so - her voice couldn't come out of her mouth and she felt there was a force forbidding her to talk about matters related to the inner voice.

She certainly knew in this world there was something called plot, heroine and protagonist.

Eiji's inner voice had so far told her.

She even knew her younger sister, even herself was one of the heroine in this world, precisely in the franchise called Highschool DxD!

Only what had happened to her?

Serafall was upset, she could only give up on the option of telling her younger sister about Eiji's inner voice.

But she should definitely beat up Eiji and not let him win in a duel!

"Enough! Eiji-chan, I still don't agree with Sona-chan being your woman. Hmph! I, Serafall Leviathan, challenge you to a duel!"

Eiji and Sona stopped flirting.

The other girls were also staring at Serafall.

They all then turned their eyes to Eiji.

Eiji sighed.

[So many things happened in one day. Author really knows how to trouble me.]

¶{Host, you should be excited! You'll get another hero in your harem after defeating Serafall!}

¶{Oh and, you should definitely woo Serafall to join your harem too!}

¶{Come on, don't leave anything for the protagonist! Aren't you always complaining about the herbivorous protagonist who always hesitates to accept girls in his harem?}

¶{You definitely wouldn't do the same with those herbivorous protagonists you hate, right!}

Miss System cheered, she seemed to be very supportive of her host building a harem.

Eiji did not deny, he did want a harem, especially a harem of beautiful girls containing heroines.

But Miss System, aren't you too excited?

You're even complaining about the protagonist that you always prevented me from doing before.

Now who did the bad thing? You did it too, Miss System.

His system even urged him, so what else is Eiji waiting for?

Although it hadn't been long since he fought all-out before, by now he had at least recovered more than 50% of his power and magic.

He knew Serafall was strong as one of the Maou in the underworld and an ultimate class devil.

The woman might also only need to put in a little effort to defeat the two Beastmen she fought earlier - if it was her.

After being slapped not long ago, Eiji did not dare to be so arrogant as to say he could defeat Serafall easily.

[No, I can't underestimate this woman.]

[My current condition isn't even 100%, this duel is actually rather unfair.]

[Do I still have to accept it? Of course, I'll do it for Sona's sake.]

[But defeating Serafall? I'm afraid it will be difficult.]

"Sure, let's do it. Serafall um..."

Serafall smiled, her smile more like a grin that couldn't wait to fight.

Or perhaps impatient to beat him up?

"Levia-tan!"

"Yes?"

"Call me Levia-tan!"

Eiji nodded. "Alright Levia-tan, I agree to duel with you. If I win, you have to approve of my relationship with Sona, right?"

Serafall slightly twisted her wand and said, "Yes, but if you lose...Eiji-chan, you and Sona-chan must not..."

"I understand Levia-tan, you don't need to explain."

"Hehe it's nice to talk to a smart person."

Sona was nervous, she was so worried that Eiji would lose!

But Lala who was standing beside her said, "Don't worry, I'm sure Eiji will win!"

The pink-haired girl seemed to believe in Eiji.

It was very different from her, and even the other girls.

Sona smiled wryly, even in this case she didn't seem to be as good as Lala?

Looks like she had to learn more to trust her fiancé.

The other girls except Serafall teleported very far away from the forest.

Only Serafall and Eiji were left facing each other.

Staring at each other for a few seconds.

Serafall sighed and said something surprising.

"Eiji-chan, how about we finish this duel with just one attack? If you can withstand my attack, I won't be opposed to Sona-chan becoming your woman."

"Huh? Are you sure?" Eiji was confused.

He stared at the woman known as siscon in the original work in disbelief.

Serafall nodded with a complicated expression, but there was still a cheerful smile on her face.

From Eiji's inner voice, she knew this boy was at least serious with Sona and not like the other bastards.

Her younger sister, Sona also seemed to really like this boy.

Of course, Serafall also didn't want to make her younger sister sad if she made her unable to be with the boy she liked.

It just depends on the outcome of this duel.

The person who can become her sister's husband, that person must have the power to protect her from wind and rain or even other dangers.

She could not possibly entrust her younger sister to a man who could not even protect her.

That person must be stronger than her or at least as strong as her.

"Yes, actually I'm just worried that the man Sona-chan chooses is unable to protect her. If one day I'm not around and can no longer protect Sona-chan, I don't have to worry about there being no one who can protect her, right?"

Although her smile looked childish, Eiji felt depressed and sad.

[Damn it.]

He suddenly remembered a certain plot in the original work where Serafall joined the endless battle against Trihexa along with three other Maou.

Trihexa or the creature called 666 is one of the final bosses in the Highschool DxD franchise.

Even the protagonist group struggles to fight the creature.

Even so, Serafall in the original work...

[Damn it.]

Serafall raised her eyebrows, she looked at Eiji in confusion.

What's wrong with this boy?

For some reason he suddenly kept cursing in his heart as if he was upset about something.

Was he annoyed because she underestimated him by telling him to decide the outcome of the duel with a single strike?

This boy, he...

[What kind of tragedy plot... Haha how stupid.]

[I hate those damn plots that put the heroines in danger.]

[What good is the protagonist if he even still lets the heroines risk their lives?]

[Trihexa? 666? That's the final boss character. With the growth of my power, I'm sure it won't take long for me to make an animal like that my pet.]

[That way, Serafall won't have to risk her life again like in the original work just to seal the creature.]

"???"

Serafall misunderstood, she was dumbfounded.

This boy was suddenly upset because he remembered herself in the original work who seemed to have a bad fate when dealing with Trihexa?

Who is Trihexa?

She certainly knew what kind of creature it was.

It was just that she was surprised Eiji seemed to care about her so much?

Even aiming to make Trihexa his pet to prevent her from sacrificing herself in the future?

Serafall stared blankly at the man whose hair gradually turned white and his eyes turned red.

Those blood-red eyes stared at her without emotion, but there was an illusion that they looked gentle as they stared at her.

Eiji Seiya, he told her something shocking, crazy and shameless.

"Levia-tan, I agree to do this duel with the conditions you mentioned. But can we increase rewards? If I win, not only Sona..."

"I also want you as my woman."

A/N 2: Most of it is about Serafall in the original work. I'm exaggerating a bit, and also this plot is a chain. It's slow, I know and I'll try to speed up the plot in the next few chapters. Right after this Serafall plot is finished. As some people requested, I'll also try to make a POV that doesn't just focus on Eiji later.
