The villain boss is the father-in-law

"Now we're really in the sky huh... Lugh, you really know how to get here normally. What you did was commendable." Eiji said and at the same time his inner voice sounded.

[Although it would be faster if we teleported from the previous location or directly flew with my magic.]

After blocking the laser attack of the defense mechanism and destroying the barrier of the Sky Library.

Unlike in the original work where the protagonist and his group were directly teleported to the island above the sky.

They followed Lugh who took them to a cave not far from Akio's hometown. Inside the cave was a teleportation magic circle that took them to the Sky Library.

Still, if Eiji could directly teleport them to the Sky Library why didn't he do it?!

The heroines who could hear his inner voice at the scene fell silent.

They didn't know Eiji didn't do it because he was a little curious about other methods to reach the Sky Library since it wasn't written in the original work.

"Can't you say thank you? You say it as if I'm your subordinate which makes me unable to stop being amazed." Lugh said flatly.

Eiji glanced at the woman with a smile. "Weren't you assigned to be our guide by the principal? That's not entirely wrong."

"You're right. I messed up."

"No, you're actually pretty."

"Really?"

"Yes."

Lugh's expression did not change but those who were there could see a slight blush on her cheeks.

While Arata was amazed and envious of Eiji because he could seduce women so casually and successfully, Lilith who saw the two getting closer couldn't stand it.

"You two! We're in the Sky Library. According to information from the principal there are many traps here so be more vigilant, okay?"

"Okay Lilith, you don't have to be jealous."

"I'm not jealous! I'm just telling the truth!"

"Yes Lilith yes I know."

"Eiji, you..."

"Hahaha!"

Lilith was tsundere as usual and she started having a verbal battle with Eiji which made Arata a little lonely.

Akio didn't care about the latter and laughed. But, soon she remembered something and asked while looking at the ruin-like environment warily.

"Still, why did we trigger the Sky Library's defense mechanism earlier? When I visited my hometown many times in the past. I didn't trigger it at all."

"Huh? Now that Akio said it..."

Lilith was confused.

"Maybe we're being unlucky?" Arata said something that made sense but Sora who heard his guess knew it wasn't true.

She actually knew the answer but should she say it?

She was worried that it might hurt her master a little but she didn't know at that moment Eiji's inner voice was telling most of them what was happening.

[You're saying we're unlucky, Arata? No, that's not what happened. There's no way we're unlucky because I'm with you guys. I am the one who is even luckier than the protagonists so far. Of course I won't say that because people will think I'm arrogant.]

The heroines: "...."

We heard it.

And yes, you are arrogant.

We think you know the real answer but—

[The reason why the Sky Library's defense mechanism was triggered was because of you, Arata. More precisely, the Magic King Element inside you made the defense mechanism react and regard you as a target that must be destroyed.]

[If I wasn't there earlier. Based on the speed and power of the magic laser that seemed stronger than the original work. Lilith and the others would probably have been seriously injured.]

[The protagonist is lucky but at the same time, he's also a trouble magnet that will trigger things that should rarely happen.]

Arata didn't know why. But was it just him or were Lilith and Akio looking at him in annoyance?

Was his guess wrong? Even so they didn't need to stare at him with such a look, right?!

This made Arata's confidence in regaining the ladies' hearts waver.

{No! Lilith, Akio. Just wait. In this mission at least I should be able to make you guys like me. I will prove my prowess as the one destined to become the Magic King. Even if I can't defeat Eiji, all the women in Trinity Seven are also destined to be mine.}

What possessive and unreasonable words you have there, Protagonist.

Eiji secretly gave Arata a thumbs up in his heart. It wasn't for nothing that he had blackened that boy for the past few days before telling Miss System to activate his inner voice.

Putting aside the other heroine.

Lilith, Akio and Hijiri who were at the scene frowned.

If they could not hear Arata's inner voice. They would never know the boy who now looked innocent had such a possessive heart.

There was nothing wrong for men to be possessive of the women they liked.

But...

Is it appropriate for a man to think that way about a woman who already has a boyfriend and has clearly shown that they are not interested in him?

Moreover, they know his plan to make them fall in love with him. So they most likely won't be so impressed with what he's doing because they know he's going to do it in the first place.

This is one of the horrors of the Inner Voice.

Arata didn't know his inner voice that could be heard by those women had made his plan futile.

"Forget it. It's already happened and we're all safe. Now why don't we start investigating this place?"

Eiji's suggestion was agreed by everyone including Arata.

Sora was happy.

She couldn't believe someone as strong as Eiji didn't know the real reason why the defense mechanism was triggered.

Even so, Eiji chose to remain silent. She had a good impression of the man but felt a little guilty for him as her master kept trying to compete with him for the women.

As their group had entered further into the ruins where they could see the castle at the top of the mountain.

Several small crystals were quietly approaching them from behind. One of them was already flying above Lugh's head and wanted to do something.

But before that happened—

"Wind Cutter."

The crystal shattered and everyone was shocked. Especially Lugh, he and the others saw Eiji had just muttered the name of an incantation and waved one of his hands.

The movement of his hand created a wind slash that shattered something above Lugh's head.

Looking at the crystal fragments falling from above her head, Lugh looked at it in horror as she hadn't noticed it at all!

"...."

"Yuki said you call yourself the Goddess of Light, Lugh. You didn't notice an object flying above your head? Next time don't lie."

Eiji said with a disappointed look at the woman in question.

Lugh looked embarrassed and frantically said, "Ah... That's because I didn't feel any magic fluctuations from that object. As for the Goddess of Light? That's just an alias Master gave me..."

"Your master is exaggerating your alias."

"...I'm actually very strong. I was just a little careless."

"Serious?"

"Super serious."

Then Lugh added while pointing at the magic suppression item Lilith had made around her neck. "If my seal is removed, I will definitely be of great help."

The look in her eyes looked suspicious as she said that.

That woman seemed to have the idea of betrayal just like in the original work.

Unfortunately not like in the original work—

"There's no need. Our power is more than enough to complete this mission. You can simply act as a guide."

Looking at the sullen Lugh, Eiji wanted to tease her further. Although it sounded mocking, he had the urge to make the woman's face show more expression.

"Eiji... This is not the time to tease Lugh-san. Except for you, the rest of us don't realize it either."

Lilith's words made Lugh have a good feeling for the girl.

Still, Lilith regretted saying that because what Eiji said next embarrassed them. At least as members of Trinity Seven and a Magic King Candidate.

"Isn't that problematic? Lilith, you told me to be vigilant earlier. But all of you now also don't seem to realize there is more than one crystal that can control people. They are now besieging us."

"I-It's indeed our fault for being careless... Sorry Eiji, wait...! You said the crystal can control people and now we're being surrounded?!" Lilith who was blushing immediately became panicked.

She and the others looked around. Arata was even still thinking of using this opportunity to show off his power.

But unfortunately, Eiji didn't give him a chance.

Even when hundreds of crystals revealed themselves and one of them tried to shoot Lilith.

"Lilith!" Arata shouted like a hero and was ready to block the attack for Lilith.

He could already imagine how grateful Lilith would be to him.

Lilith who sensed the danger approaching her from behind froze.

Eiji rolled his eyes and snapped his fingers while muttering.

"Reflect Wall."

The previous spell and this was Varvatos' magic spell.

A transparent purple colored barrier appeared and enveloped them all very quickly.

It was faster than the attack that targeted Lilith and the other shots that targeted everyone.

The man in the gloom was clearly playing more seriously than he was in the original work. It must be because of the Cero shown by Eiji earlier.

Even so, Eiji did not panic.

His barrier was very strong and had the ability to reflect all the attacks back to all the crystals flying in the sky.

*Boom!* *Boom!* *Boom!*

Explosion after explosion like fireworks were created around them. In a short time all the crystals that were magic items or something made by someone were destroyed.

Arata who lost another chance to show off because Eiji moved too fast cried in his heart.

{Why, Eiji?! Can you let me show off a little? You're monopolizing all my moments!}

The heroines: "...."

Eiji: "...."

Is the protagonist so impatient and getting childish?

Their situation was not a game. If Eiji didn't move first. Was Arata sure he could block all those attacks and destroy all those crystals at once? Many of them doubted.

They would rather rely on Eiji who was a safer option than risking their lives by relying on Arata.

While Arata didn't realize many women including Arin and Yui even felt a little disappointed in him.

Lilith looked at Eiji gently. As expected of her boyfriend. He could protect her at any time.

After the dust outside disappeared and Eiji deactivated his magic barrier.

Akio of course admired what Eiji had just done. Still, she couldn't help but ask about what had just happened.

"What was that? I know this place has a lot of traps but I feel like that was too much... Or is it usually like this?"

Akio's gaze fell on Lugh who had previously stolen three metals with pointed tips. Cough, Mythical Armaments in the Sky Library.

Lugh who felt everyone's gaze said, "When I tried to infiltrate the castle that holds many treasures on top of the mountain. I wasn't surrounded by that many traps."

When everyone except Eiji who heard Lugh's experience was confused.

As usual Eiji's inner voice was a strange thing. Instead of telling them directly, he said what he knew in his heart.

Honestly the heroines didn't understand why the man liked to pretend not to know.

[That's natural. After all, when Lugh tried to steal the items in the Sky Library in the past. That man who hid in the castle and at the same time was the one who created those crystals that could shoot lasers and control others.]

[He was too lazy to notice Lugh and ignored her existence. He did not attempt to control most of his toys just to kill her. That's different from what he did to our group.]

[In the original work Lugh would be controlled by one of the crystals to attack Arata and the others before being freed by a few shots. And Lilith who was hit by a laser attack from one of the crystals would be knocked unconscious so that the Magic King Element inside her body was awakened.]

[You could say that the reason why the man living in the castle was eager to deal with our group was because of Lilith's existence.]

[He is her father after all.]

!!!

The heroines who were listening from other places were amused when they heard this kind of thing.

However, those who heard it at the scene really felt like they were the audience of the drama. For example Hijiri, she who was secretly watching everything that happened from Eiji's neck with Ilia began to enjoy herself.

Only Lilith who if she knew what those women were thinking wanted to shoot some of them with her magic rifle.

This matter was serious to her.

It turned out that the man who had just attacked them with his toy was her own father!

As for the Magic King Element inside her body? Lilith had long known from the inner voice of her boyfriend, Eiji before they came to this world.

She knew there was a Magic King Element sleeping inside her body and her father wanted to kidnap her because she was something called the "Last Key".

[Akio is also good at pretending, by the way. With her real identity as Spriggan, the protector of ruins and castles containing legendary treasures stored in the Sky Library.]

[She should know more about this place than Lugh. I don't understand why that woman hid it until now. I also don't understand why people who know a lot pretend not to know.]

While Akio was dumbfounded that her true identity was known by Eiji. She and the other heroines had the urge to spit.

Some of them even wanted Eiji to look in the mirror when he said the last part because he himself was a person who liked to pretend not to know!

He even did it every day as if he didn't pretend, he would feel uncomfortable.

[Host, you are...]

What? You wanna call your host shameless, Miss System?

Eiji had heard this hundreds of times so he definitely wouldn't take offense.

[No, it's nothing. Continue.]

Miss System who knew what the man was thinking chose to keep the sentence "Host, you are a shameless person as always." in her heart.

"...." Eiji.

At this moment seeing that many of his toys had been destroyed.

A man finally couldn't stand it anymore. He appeared early with the entrance: the sky suddenly darkened, a magic fluctuation similar to the Magic King Element descended from the sky along with a gust of hurricane wind in which there was a figure of a man riding a dragon.

"T-That is...!"

"This power, this is the Magic King Element!"

Lilith and Sora shouted dramatically.

Sora was understandable because she didn't know. But Lilith, shouldn't she have guessed who was coming?

Eiji shook his head.

When everyone in his group was nervous and Lilith's father who had landed and showed himself was about to say something.

Eiji made an unexpected move. He pulled Lilith into his arms which left everyone dumbfounded.

"Eiji? W-What are you doing?! We're in this situation... You should at least be patient until we get back to school..."

Lilith's face turned red and looked very shy. Even so she curled up in Eiji's arms. The words that made others misunderstand and her actions made Arata's heart bleed and her own father almost fell off his mount.

As for the women? They were now staring at Eiji's handsome face. To be honest they were a little envious of Lilith rather than worried about the men's reactions.

Lilith misunderstood him, but Eiji was happy to hear what was said. Didn't that mean he could eat with her? For a moment he wanted to immediately take Lilith back to school rather than continue this plot.

But hey luckily he was a patient person. In one second the dirty thoughts inside his head were immediately cleared.

According to Eiji, he entered a state of mind similar to a Buddha or an angel like Michael.

Although in reality he was still some distance away from that. After all at this moment Lilith felt something rather hard poking her stomach.

Eiji ignored Lilith's question and said to his father-in-law.

"Who are you? You're scaring my girlfriend."

Lilith wanted to argue who was scared of whom? But her father's shout startled her a little.

"Girlfriend? That means... you're my daughter's boyfriend?!"

The man, Lilith's father took off his mask and revealed a face that was familiar to everyone. His expression seemed a little ugly and very cold.

Arata and the women were naturally surprised. Lilith stared at the man with a strange look.

Despite looking more mature why did her father have a face that almost looked like Arata?
