Reincarnated and traveling to another world, Eiji Seiya initially thought the world was normal. That was what he thought before he met the heroine and protagonist of the franchise he had watched in his previous life. Not only that, after he awakened the Inner Voice System to grow strong by complaining about plot, heroine and protagonist in his heart to get many rewards. He is determined to increase his power so that he can save his home world, the world where he was reincarnated that was hit by the disaster "Honkai" and save beautiful girls like Kiana, Mai, Bronya, Rita and others who had tragic endings in the original works! "I will save them all!" However... Everything went smoothly... Eiji earned rewards every time he changed the plot in another franchise. It's just that... What's wrong with these heroines? Lala Satalin Deviluke who was supposed to be engaged to the protagonist instead became his fiancée. Sona Sitri suddenly called him to the student council office and said she wanted to make a deal with him. Rias Gremory who was supposed to ask the protagonist for help to solve her political marriage problem with Riser Phenex inexplicably came to him. The girls were disgusted at the protagonists of their respective franchises. Something was wrong here!

Is this the life of a harem protagonist?

Seeing his reward, Eiji couldn't help but be surprised though he soon calmed down.

Of the two rewards, he felt familiar with the first one. Asking Miss System to tell him the description of the reward, and it was correct.

"Master-Servant Contract."

This was a magic derived from a certain franchise that was actually somewhat similar to Highschool DxD.

The resemblance doesn't come from the perverted protagonist, or the protagonist's obsession with breasts, but the concept of the franchise is the same!

It basically has elements of Magic, Modern World, Demons that are not Devils, and Various Other Races. The world setting is almost the same as Highschool DxD and the protagonist in the franchise itself is a cool guy who is at least better than Issei because he's not herbivorous.

In Eiji's view, a protagonist who is at least not blushing and embarrassed to do lewd things to the heroine is a decent enough protagonist.

And the Master-Servant Contract magic itself was a unique magic created by the ancient demons in that franchise that happened to be learned by the protagonist.

If not for this magic, the relationship between the protagonist and the heroines in the franchise would definitely not have escalated so quickly.

Just as the name suggests, this is a magic that can bind a person in a master and servant relationship where the master can ensure the loyalty, condition, location, and increase the power of the servant as loyalty to the master increases.

There was also another feature that Eiji liked the most about this magic. It was a barrier feature where if the servant was a woman, then no other man could touch the servant carelessly with malicious intent or anything like that. If any man dared to touch his servants with evil intentions, a magic barrier would automatically appear to protect the servant and the power of the barrier depended on how strong the master was.

In his case, Eiji believed there were not many people capable of breaking his barrier in this world.

So he really liked it.

A possessive man like him loved this kind of magic so much, he even sent a "Love" emoticon to Miss System for giving him this which made her speechless.

¶{Glad you like it.}

"Miss System, you are very beautiful. If you can, you should give me useful rewards like this more often."

¶{Hum! You don't even know how pretty I am. How can you call me beautiful? Flattering me won't get you anywhere, after all, rewards are random.}

"Yes yes random, I believe it's random."

Eiji didn't believe it and he was too lazy to argue about how his system worked.

But certainly, besides the advantages that this magic had, there were also disadvantages of course.

What are the disadvantages of Master-Servant Contract magic?

Well actually this can also be considered an advantage.

For example if a servant tries to commit a treasonous act or feels guilty towards their master, a magic collar of varying colors will appear around their neck and trigger a curse effect. The curse is not too serious, but it also depends on how bad loyalty or resistance the servant has to their master.

In the original work, a red-haired heroine somewhat similar to Rias several times triggered the curse effect of the Master-Servant Contract magic which made her exposed to an aphrodisiac effect where she craved the touch of the protagonist who was her master.

The protagonist had to do lewd things to the heroine in order for the curse effect to lift and she could return to normal. Actually, thanks to this incident, the relationship between the protagonist and the heroine also became closer.

The heroine who initially didn't like the protagonist much slowly began to like the protagonist more and more after receiving many touches and doing lewd things with him under the effect of the curse.

The protagonist's routine of capturing the heroines in the franchise was actually like that.

It was devious even though on the surface the protagonist seemed innocent and forced to do lewd things to the heroines.

His actions are almost the same as some hentai protagonists.

Eiji had no problem with what the protagonist did, and in fact if he were in the protagonist's shoes, he would probably do the same thing.

Eiji was thinking of using this magic on the girls in his harem and his subordinates in Shadow Garden. But of course, he wouldn't force them and explained honestly what the advantages and disadvantages of Master-Servant Contract magic were.

Cough, next! The other reward was something he did not know unless he checked the description.

And after he checked it, he widened his eyes, his eyes sparkled, and the corners of his lips curled up like a villain. Oh no, he wasn't a villain. Maybe.

It was just that after reading the description of "Sub-System Maker" on the system interface, Eiji suddenly had an evil idea to deal with Euclid, Rizevim, the protagonists and other characters who might oppose him in the future.

Why? It was because with this reward, he could create a system for others! This system will certainly not be as great as the Miss System, just like its name, this is a Sub-System that is basically a small version of the main system.

By making the Miss System the main system that controls the flow of sub-systems in a person's body. Eiji could manipulate and deceive the people he targeted.

For example, he could give a system to a protagonist and that system had a random quest function to get rewards that could trigger the protagonist's greed.

The type of system, quest and reward that the protagonist would be given was also up to Eiji and that was what made him smile like a villain. After all, with this ability, he could lead the actions of others to gain benefits for himself!

However, there are also limitations on his abilities that prevent him from creating as many systems and rewards against targets as possible as he still has to use system points to do so.

And the thing called system points was also something he actually had since the previous system update where he finished killing the protagonist for the first time.

You remember after killing Issei? His system points so far after he double-checked, it turned out that it had accumulated quite a lot.

[System Points: 36,000]

The so-called system points were naturally earned from his actions to change every plot of the various franchises so far.

With this point, Eiji could create a Sub-System to send to someone.

Just now he was excited to try it out, but at this moment a charming female voice interrupted him.

"Ufufu. Good morning, Eiji-kun."

"Morning Akeno."

The girl who woke up first was Akeno. The black-haired beauty was wearing a yukata with thin fabric. While hugging him, he could feel her breasts, thighs, and the sensation of her skin under the thin fabric that was transmitted directly to his body.

Her hair that was usually tied in a ponytail style was now flowing like a disheveled waterfall after waking up.

Her purple eyes that still had a slight layer of haze looked at him so closely...

[Now I understand why many men like to wake up with a woman beside them. Of course, it's not my first time. It's just that Akeno's body is too lewd.]

[What man could stand it?]

"You never hold back, you know?" Akeno's sweet voice tickled Eiji's ears. She squirmed, hugged him tighter and pressed her nose against his neck.

"Akeno, what are you talking about? I don't understand. Are you a dog by the way?"

"To call his beautiful girlfriend who sniffs his neck, you call her a dog? Fufu. This is really Eiji-kun's style."

"My style? No, Akeno my style is..."

"Want a good morning kiss? I heard men really like it."

"Sure."

That was Eiji's immediate answer in 0.1 seconds, no hesitation, no blush on his thick handsome face. The silver-haired man looked at the black-haired woman as if saying "Do it".

Akeno giggled, lifting her body, trying not to nudge Lala and Rias who were also hugging Eiji. She crawled beside the man and bowed her head.

Chu~~

[Ah... This is it. It's a very good morning! For the harem protagonists out there, if you have a harem, you're a waste if you've never gotten a good morning kiss when you wake up.]

Eiji grabbed Akeno's waist as she gave him a hot kiss, her tongue entering his mouth and their tongues entangling with each other.

The lewd sound of the kiss rang out in the room.

However, perhaps because of his inner voice, a flat-chested girl could not stand it and broke the door of his room.

Boom!

"Eiji! You animal! What are you... Huh? Y-You, with Onee-sama, Rias, and... You dare to kiss Akeno in that situation?!"

Who else would it be but Nana? Just woke up and finished bathing, but heard Eiji seemed to be doing lewd things in his room. She snorted and prepared to catch the scene of the affair, once the evidence was obtained she would report it to her older sister that her fiancé was a bastard.

But the situation in Eiji's room left her dumbfounded because not only were there two sexy girls she had just met yesterday, there was also her older sister who seemed to have slept with Eiji all night!

This made her who originally wanted to reveal the infidelity scene freeze, and the scene of Eiji kissing Akeno didn't help but make her face red.

"Ara. Nana, good morning."

"M-Morning, Akeno, you..."

Akeno greeted the girl, but that was all before she lowered her head again to kiss Eiji.

Chu~

"You still want to continue?!" Nana was dumbfounded.

[Nana, Akeno is not a thin-skinned girl like you. She wouldn't be shy to kiss her boyfriend or even do lewd things in front of other girls.]

That's true, but that last one is a bit much, okay? I don't have exhibitionist hobbies like Rias. If it's just Nana, Lala's younger sister, or the girls in this house, I'm fine with it.

Akeno complained in her heart, but it wasn't long before she was immersed again in the thrill of the kiss while ignoring the existence of the girl standing in the doorway.

Nana opened her mouth, not knowing what to say, but she just remembered that Akeno and the red-haired girl named Rias were also Eiji's girlfriends.

So trying to catch this cheating scene in the first place was pointless! Her older sister, Lala didn't even mind Eiji adding more women to his house!

But still, for some reason Nana felt annoyed to see Eiji kissing in front of her eyes.

"Akeno. What did you do to Eiji?"

A charming voice came again from the side, everyone turned their heads and saw the red-haired girl just waking up with half-closed eyes that were very unhappy.

Unlike Akeno, Rias was wearing red lingerie that almost matched her hair. The outfit was no less sheer than Akeno's, people could see her super voluptuous figure with her disheveled hair that made her even more stunning.

Nana's gaze naturally fell on that figure, especially on the breasts. Damn it! She was so envious! Akeno too, that girl has a really good figure!

Why?! Why are these girls growing so much even though they are only two years older than her? Her older sister who also has a good figure also seems to be less voluptuous than those two girls.

Even so, Nana suddenly had an idea, her eyes sparkling, she pointed at Eiji and said: "Rias, you should know. Eiji and Akeno just kissed while you and Onee-sama were sleeping!"

"Oh?"

Rias turned her head towards the door, she looked at Lala's little sister for a moment before looking again at the direction that seemed to be true Akeno had just kissed with Eiji.

Nana was excited. If she couldn't make her older sister scold Eiji, then she could try to make the other girls in Eiji's harem do it!

She just wanted to see Eiji scolded for being too bastard.

And someone could finally do it for her!

Eiji and Akeno looked at each other, they were again interrupted while kissing.

"It's already morning, we should get out of bed and prepare for school." Eiji said the thing that good students usually said even though he wasn't one of them.

The two girls with Onee-sama's temperament ignored the man and looked at each other.

Nana wanted to say once again that she was very excited at the moment! Eiji, you died this morning!

"....." Eiji glanced at the girl flatly. Nana, you think I'll be at a disadvantage in this situation? You're naive!

You don't know what Rias and Akeno were like in the original work in this situation. If you did know, you'd be surprised even though what happens next will also surprise you.

"Rias, morning."

"Morning, so what are you doing? I remember when I snuck into Eiji's room there was only Eiji and Lala." Rias didn't bother to hide the fact that she snuck into his bedroom last night.

"Isn't it obvious? I also sneaked in here last night. As for what I did? I had a nice morning skinship with my Eiji-kun." Akeno licked her own lips as if showing off.

It was true Rias gave Eiji the green light to have multiple girls, she had even serviced him with another girl not too long ago. But that lewd situation strangely didn't make her as jealous as this situation, she was still a jealous girl and her vinegar jar wasn't big enough to not make her gasp seeing her fiancé being kissed by another woman. She was beginning to regret pushing Akeno onto Eiji in the past.

Last night, seeing Lala already ahead of her sleeping in with Eiji as well, she was extremely jealous and wanted to separate the pink-haired girl from her man's body.

But she couldn't do it! Because she knew that if she did such a rude thing to Lala, Eiji might feel displeased with her. So she could only endure the jealousy by hugging him too while sleeping.

Now hearing what Akeno said that it was obvious that the girl was provoking her, Rias' eyebrows raised.

Yes! Yes! Yes! Nana cheered, she didn't expect the girls' quarrel in the harem to be more fun to watch than the anime she usually watched with her older sister.

Eiji also looked at the scene in front of him with an interested gaze, he saw Rias' body tremble slightly as if holding back from exploding her devil power.

Wait, he felt this scene was familiar. Didn't Issei also experience it in the original work? I mean the quarrel of the girls in the harem in her bedroom? It's just that there are also girls from other franchises like Lala and Nana. Eiji wasn't sure how this situation would continue, and he didn't want to use "Future Sight" just for that.

"My? Isn't it too much for a boyfriend to say that in front of a fiancee? There's a gap in identity. Akeno, aren't you embarrassed?"

[Wow! This quarrel is a bit more spicy than the original work!]

Rias' lips twitched, so she had also had a fight like this with Akeno in the original work? If the girl was Akeno, she had no doubt that the two would indeed quarrel.

But so what? Rias looked at Akeno arrogantly.

Akeno smiled darkly. Oh, she had already entered the offended Onee-sama mode.

"Embarrassed? Fufu. Rias, I'm one of Eiji's women after all. Can't I sleep with him and give him a kiss during the morning?"

"No, if there is your master around Eiji, you can't do it!"

Akeno widened her eyes as if surprised, she brought her face closer to the red-haired girl.

The two of them crawled in the middle of Eiji who was hugging Lala.

The purple and green gazes met fiercely.

"Ara-ara. Is that what you said, Ojou-sama? Is this Ojou-sama's order to her servant? I didn't expect Rias Ojou-sama to compete with her servant in this way. If she felt at a disadvantage in the love competition, she would use her status to pressure her servant." Akeno's tone as she said all that sounded very mocking.

Rias' body shook violently, she opened her mouth several times before saying: "No! How could I be that small? Akeno, I didn't order you as your master, I only banned you as Eiji's fiancée."

"Isn't that the same thing?"

"That's not the same! From now on, this room is a place that only Eiji's fiancée can enter. Except for Lala and Sona who have fiancée status, I won't let other girls stay in this room! Akeno, you must understand. There is a difference between a wife and a concubine."

[Since when is there such a distinction in my harem? I don't actually distinguish the status of my girls.]

"Baby, please be quiet, okay? This is the problem of the girls in your harem. I won't blame you for being tempted by a lewd girl like Akeno in the morning." Rias looked at Eiji with a smile that was quite frightening.

"I didn't say anything."

"I know, I just wanted to say it."

Eiji wasn't afraid of Rias' smile, but he glanced at Nana who opened her mouth in disbelief.

[You heard that, Nana? Hahaha! Who do you want to anger? Me? I'm innocent! My girls love me so much, I suggest you stop fantasizing that I'll be scolded by one of them.]

[Instead of continuing to fight with me? How about becoming one of my girls? I feel sorry for you, protagonist Rito isn't even particularly interested in you, so I'll reluctantly accept you.]

[If you beg of course.]

"Bah bah! Eiji, you bastard! Shameless bastard! Rias, Akeno, did you hear that? You guys should at least scold that man!"

Nana pointed at Eiji with a red face from embarrassment and anger, she hoped the two girls were as angry as she was because they could also hear Eiji's inner voice.

From the mouth of her older sister, Lala. She and all the girls living in Eiji's house had been told the truth that all heroine could hear inner voices. So Nana was sure Rias and Akeno could also hear the words of the wolf that Eiji had said.

That man should be scolded right now!

However, the two girls in question glanced at her instead of at the man she was pointing at. It was their glowing gazes that made her shudder.

"Nana, why don't you go for breakfast first? Grayfia must have finished preparing it."

"Fufu. That's right, Nana. You should have breakfast with the others first. We'll catch up in a bit.

"Why?" Nana looked sad, she felt that these two girls didn't know what was wrong and right.

They really couldn't speak human language.

What good is Eiji Seiya?!

[Hahahaha!]

Eiji burst out laughing, on the surface he seemed calm even though his lips were trembling and looked at Nana comically.

Nana gnashed her small tiger teeth, she looked angrily at Eiji and this time she also looked at the two Onee-sama with an unfriendly gaze.

"Hmph!" Nana snorted and said while pointing at the two girls in front of her. "You two. Are you two kicking me out?"

Eiji shook his head. Nana, you don't know who the girls you're facing are. Deviluke is strong, but you're not as strong as your father.

The two girls in front of you are not ordinary girls either. You should know from my inner voice all along that they are both Devils! Although they look beautiful and voluptuous, they are strong and can defeat at least a dozen of you in one shot!

"Yes." Rias and Akeno said simultaneously, they found the presence of a little girl like Nana disturbing.

"You guys..." Nana felt humiliated at the gaze of the two girls who didn't seem to take her seriously. "Don't be so arrogant, you two!"

Who's the arrogant one?

"I'm Deviluke's second princess!"

"So?" Rias tilted her head in confusion. Isn't that only the second princess? Not the first one?

"My Dad is the Galactic King, he's one of the guardians of this universe."

"Ara-ara. Your father is great. So Nana, is that all? If so, please leave. I have things to discuss with Rias."

"Nana, it's not good to delay breakfast for a girl your age who is still growing up. I also still have to talk to Akeno, so please leave."

"...."

Nana puffed up her cheeks, her eyes red with anger. She really was being belittled and looked down upon, wasn't she? Rias even dared to mention her growing up years. Ah! Ah! She unconsciously glanced at her flat breasts and glanced at the breasts of the two girls.

The difference seemed to be like an asphalt road and a mountain range!

With her temperament, she certainly wanted to explode and fight with the two girls after being looked down upon so far.

But when she saw the two smiling with a terrifying aura enveloping their bodies.

Nana swallowed, her body trembled, and she just realized the two girls in front of her seemed to be much stronger than her.

In the end, feeling intimidated, she grunted and ran out of the room.

"Woooo! Momo, your Onee-sama was bullied by two devil girls!"

You ran away crying?

Even complained to your younger sister downstairs?

Eiji shook his head again. He looked at Rias and Akeno and it seemed like they still wanted to continue their argument.

At this moment, the last girl in this room finally woke up.

"Fuaaa... Is it already morning? Eiji?"

Lala rubbed her eyes, she completely ignored the two girls fighting behind her and hugged her lazily.

"Lala, morning. Why don't we go take a shower?" Eiji stroked the pink-haired girl's head gently. The girl hummed like a cat.

Ah... That's right. Lala is the best! Just watching her stare at him with sleepy eyes that were innocent yet began to shine cheerfully slowly.

I feel healed!

"Together?" Lala's eyes lit up.

"Yes, I'll wash your hair."

"Yeay~! I want to! I want to! Eiji, take me~!"

After that, what else was there to say? Eiji teleported to the bathroom with Lala. They took a shower and scrubbed each other.

It was a beautiful morning until the quarreling Rias and Akeno realized Eiji and Lala were gone.

Bofu!

"Ah! Akeno, it's your fault! Eiji left me and took a bath with Lala!"

Rias threw a pillow at Akeno's face with watery eyes. The black-haired girl widened her eyes.

"Ara, so what? You're so stingy Rias! Lala is also Eiji's fiancee. Didn't you say she was an exception? Those things about the fiancee? Fufu. Just admit you really just want to monopolize Eiji-kun alone, Rias!"

She picked up the fallen pillow and hit Rias in the face with it. There was a golden aura on her body that didn't add any damage to her attack.

Rias pushed the pillow away from her face, her red aura still enveloping her body, she looked at Akeno with even more watery eyes.

It seemed that the two girls would continue to fight like children with such large bodies.

[Instead of bickering, it's better that you two also take a bath with me.]

"Kyaa!"

"Ara-ara, Eiji-kun~"

Eiji teleported again from the bathroom with a wet body, he immediately hugged the two girls and teleported again to the bathroom.

Really, it was a troublesome and at the same time fun morning.

Is this the life of a harem protagonist? I love it!

...

[Ding! Congratulations, out of the trillions of people in this universe, you are the only one chosen.]

[The system has bonded with you.]

[From now on. Money, magic artifacts, super abilities, and other things from various universes can be obtained by completing system-given quests!]

[With the help of the system, your mediocre and boring life will become extraordinary like the protagonist in a novel, anime or movie! You will become the protagonist!]

"...What is this?"

Rubbed his eyes a few times.

At school, in the service club to be precise. Hachiman stared at the transparent gold-colored screen containing text in front of him in confusion.

He had just arrived at the club room, Yukino as usual was already there and she was reading a book without even glancing at him even though she realized he had come.

It was still the same as always, that girl was just like that.

Although it took a longer time, Yukino finally glanced at him and asked. "What's wrong with you?"

"What? What do you mean?" Hachiman asked in confusion, but then he glanced at the golden screen floating in front of him and said. "I-It's... Yukino, do you know anything about this thing?!"

Yukino gave him a strange look. "Thing? What thing are you referring to? I don't see anything."

"You really don't see it? This thing I'm pointing at?"

"No. Hachiman, I don't see anything. Are you joking with me? Too bad your joke was bad."

Yukino had a poisonous tongue as usual. Hachiman scratched his head, he wanted to convince Yukino that he wasn't joking, but...

[Host, please calm down. The system can only be seen by you. No one other than you can see me.]

[Also you can communicate with me through your mind. You must do this to communicate with me so that you won't be considered crazy by others.]

Hachiman widened the eyes of his dead fish, this thing can communicate like a person?!

[Please don't underestimate this system, host. I'm so smart, you can think of me as being as smart as Iron-Man's Jarvis.]

'Jarvis? Who is that?' Hachiman calmed himself down, he was following the idea of the thing called the system to communicate through thoughts.

He also didn't want Yukino to think he was crazy for talking to himself.

[Ah sorry, there are no Marvel-made movies in this universe. Never mind, you just need to trust me and use me for yourself, host.]

The system's voice was that of a man in his thirties who was masculine yet emotionless. Hachiman was a little uncomfortable hearing a man's voice in his head.

But trusting this thing called the system? You mean about the things he said at the beginning?

Hachiman hesitated, he certainly didn't easily believe in such an amazing thing actually existing even though the golden screen-like thing in front of him was also unusual and like a super ability.

However, as if seeing through his doubts.

[I know you doubt me. How about this, I'll give you a small quest that's easy to do and you'll get a reward for completing it.]

'That's kind of fair... Okay, let's try to do it.'

[Ding! The system has released a quest!]

[Quest: Open the browser on your phone, find a video of a femboy singing for more than 5 minutes and play it to the end with the highest volume in the service club.

Reward: 100,000 yen transferred directly to your account.

Time limit: Must start 30 seconds from now. (Note: If later than that, the quest will be considered failed and the system will be disabled for three years)]

"Excuse me?!"
