Leaving aside the original Lucifer, at least for now.
Niu Niu no Mi? Zoan type?
Eiji didn't know much about One Piece, but he had read the list of devil fruits and various types on the Wiki in his previous life.
He was sure none of them were named 'Niu Niu no Mi'. There was one with almost the same name called 'Nui Nui no Mi', but he remembered it was a Paramecia-type Devil Fruit.
It was definitely not a Zoan-type Devil Fruit...
[You won't see it in the original work and the author of the original work doesn't mention it. Besides, 'Niu Niu no Mi' is a devil fruit that came from a Fanfic! Just eat it, okay?]
So it came from Fanfic.... Eiji just found out his system can take things from fan works.
Still, eat it?
"Is this fruit even useful for me? I've already eaten Doku Doku no Mi' before."
Doku Doku no Mi or Venom Venom Fruit was a Paramecia-type devil fruit. Even that devil fruit was of little use to him now that he had an innate ability regarding the poison that the Poison Primogenitor possessed.
Jörmungandr's poison was clearly much better than Doku Doku no Mi's.
Unlike the Paramecia-type devil fruit which allows one to manipulate the environment, affect their body or produce substances.
The Zoan-type devil fruit allows the user to transform into animal species at will, or hybrids between species that each possess extraordinary powers.
Instead of eating them for himself, he prefers to give them to his women as he dislikes turning into animals. Jörmungandr is an exception because he thinks it's cool to be a huge snake whose size surpasses the planet...
Wait, he doesn't want his women to become animals or other ugly creatures either! It's fine if the animals in question like Nekoshou, Koneko and Kuroka still look pretty and cute in their half-cat and cat mode. But it would be bad if it was the other way around!
Eiji knew that not all Zoan-type devil fruits gave their users a good appearance when using their devil fruit abilities.
So—
[That's why I told you to eat it, host. Although the ability Niu Niu no Mi has won't look good on women, it will at least look better when used by men! You'll look more intimidating when you use the fruit's ability to slap your enemies! This fruit has the power of the legendary sacred beast called Qilin!]
"Qilin? Isn't that..."
Eiji's lips twitched. He examined Niu Niu no Mi in his system interface.
The fruit was red with a golden flame-like pattern coating its skin. It was obvious that its main ability was fire.
Well so far he did not have any prominent fire powers. So this was actually a pretty good addition.
The description explained that the fruit had the ability of the sacred beast Qilin which was famous in the legends of various countries in East Asia.
Miss System must have read Fanfic written by easterners not long ago. That was why she had the idea to give him this!
He was reluctant to eat it, after all, after eating it, his combat power was estimated to have only increased slightly.
But power is still power, increasing his power is definitely a good thing. As for the matter of appearance after he ate it? Fortunately the description said that she was free to choose to display his Qilin form or not when using the abilities that Niu Niu no Mi possessed.
And since it's a system product, side effects such as weakness to sea water and sea stones are of course eliminated.
System products always put the convenience of their hosts first.
This is the only good thing when the rewards given by Miss System are not very good.
[Host, if you don't want it. The system has a feature to throw rewards into the trash.]
Eiji pretended to cough and smiled, he did so while taking out the Niu Niu no Mi fruit from the system inventory before saying: "Don't say that. The things Miss System gave me, how could I not appreciate them?"
"The Qilin form can be used to slap someone in the near future."
Don't know who Eiji was referring to, but Miss System and Leme knew.
As her contractor ate the strange fruit that suddenly appeared out of thin air, Leme couldn't help asking. "My king, Leme has long been curious... Where did you get those strange fruit-like items and who were you talking to? By the way you had unlocked Agares last night. The Heart Key of the blonde woman with glasses matched the lock of one of my subordinates."
Eiji who was eating Niu Niu no Mi fruit slowly and enjoyed the taste of devil fruit that was not like the trash in the original work. The flavor of the fruit was almost similar to an apple, although the fruit seemed to be burnt by the fire which made the scene on the bed strange.
He said to the silver-haired loli that materialized itself in the air, "Really? That's good. As for this fruit? I got it from my other golden finger. You don't know and can't feel it, but besides you, Leme. I have another woman inside my head."
[I'm just a system... Who do you call a woman?]
Eiji ignored the dishonest woman and looked at Leme.
Leme was now flying over Koneko and Irina who were still asleep and staring curiously at the fruit he was eating. She widened her golden eyes slightly after hearing his words.
She looked cute.
Eiji wanted to ask the loli to transform into her voluptuous adult form because he knew she could do it. But he had just finished eating a lot of meat, so let's save Leme Onee-san for later.
"Hoh~ Now that makes sense... So there's another woman besides Leme who became your golden finger? Leme is unable to sense her existence, she must be stronger than her." Leme said while ignoring the lack of enthusiasm and the hot gaze of her contractor. Of course she knew Eiji was thinking of her adult form and gave him a mischievous smile.
The man was naked with a blanket covering his lower half and displaying his explosive upper half like a Greek god statue. No, the Greek god statue wasn't even as good as his body.
Leme had to admit that out of all her contractors so far; not only was she more skilled at picking up girls, Eiji also had the best body which even made her horny.
[That's right, I'm stronger than you little girl! A hundred million years too soon for you to be able to sense my presence unless I take the initiative to reveal myself!]
Eiji rolled his eyes. Miss System, don't be so arrogant...
And there you seem to have just admitted something.
Leme didn't notice Miss System's shout and the latter had no intention of getting in touch with that loli.
Ignoring both of them.
After eating Niu Niu no Mi to the end. He didn't feel much change in his body, but he did feel that he had gained some new abilities.
"Now where should I test it?"
...
Incidentally, shortly after that.
It was 10 am where the girls who had been exercising intensely last night finally woke up.
Except for them, the others had gone to school.
As for them? They were like bad students who skipped school and were relaxing at their house.
However, it wouldn't be a problem because they had Rias and Sona.
Rias: "...."
Sona: "...."
The two devil girls were discussing something with a few other girls including Seekvaira in the living room. The blonde woman had officially joined his harem and they seemed to be discussing getting her to move into Eiji's house.
As for Eiji, he was staring at the beautiful light blue-haired girl sitting beside him. Even before the other party spoke, he could already guess that it was time for him to deal with the plot of "Shinmai Maou no Tastement" again.
Originally he wanted to go to continue the route of Utaha, Chisato or even Aika at school, but another route came earlier.
"Eiji, this might be a little inconvenient for you..." Yuki said hesitantly. The expression on her kuudere face showed a hint of anxiety after she hung up the phone call from her younger sister, Kurumi.
Last night unlike her older sister, Kurumi did not join the orgy at her boyfriend's house because she received a call from the village.
It was the hero clan, her father asking her to return for unexplained reasons.
"What's wrong, Yuki? Did something happen to Kurumi?" Eiji asked casually. He wasn't worried about anything bad happening to Kurumi because if something really happened- the Master-Servant tattoo on the girl's neck would give him a signal.
At that time, he could instantly appear beside her in less than a second and see who the mongrel was that dared to mess with his woman.
By the way Yuuki who had been pounded many times by him last night exuded a stronger feminine charm around her. Her breast size slightly increased from before and made her slim figure even more voluptuous.
As expected of a Master-Servant Contract.
What a wonderful effect...
"No, Kurumi is fine. It's just that she told me that the village elders want to meet Demon Lord Wilbert's daughter Mio and... You, Eiji. They invited you to come there." Yuki said, her hand hugging one of Eiji's arms. Her face lacked expression, but her coquettish movements and emphasizing her breasts would make it difficult for men including Eiji to refuse her.
After more than a month of being Eiji's girlfriend, she seemed to have learned many tricks to seduce a man.
"Eh, me?" Mio happened to hug Eiji's other arm and pressed her large breasts against the man's body.
The Demon Lord's daughter certainly didn't want to lose to Hero Kuudere.
Still, she was a little surprised to hear that people from the hero clan other than Yuki, Kurumi and Basara that she knew wanted to meet her.
Those people even invited Eiji. The Demon Lord's daughter frowned.
"Yes Mio, who else is Demon Lord Wilbert's daughter named Mio here?"
"You... I know, but what for?!"
Mio pouted, she glared at the light blue-haired girl in annoyance.
Don't get me wrong, their relationship had evolved a lot since the battle in Demon Realm. They got along well and became sisters who could serve Eiji together at night.
But sometimes they would still argue and compete with each other, especially when Eiji was there.
"Well Mio, calm down... Yuki, do you know what their reason for doing this is?" Eiji hugged the Demon Lord's daughter's soft waist which made the girl blush and rest her head on his shoulder.
Even so, her pink eyes still looked at the blue-haired girl with annoyance and said: "Hmph! I'll spank your ass a hundred times later."
[Heh, that's different from usual. I remember Mio's usual slogan was "I'll kill you a hundred times!", now it changed to spanking ass huh? How cute, Mio.]
Mio's face was hot... She didn't expect Eiji to remind her, her heart felt a little sweet.
"Cih!" Hero Kuudere, Yuki clicked her tongue when she saw the soft air around Mio and Eiji. Obviously Eiji was also her boyfriend, but look at the Demon Lord's daughter, just because of that she started hugging the boy tighter and sniffing his neck like a bitch before her eyes.
How dare she.
As expected of the Demon Lord's daughter. Last night's intense workout wasn't even enough to make her stop lusting for a day.
Yuki wrapped her arms around Eiji's neck, she shamelessly rubbed her hero's much-developed body on the boy's body. Then, she brought their faces close to each other in front of Mio.
Eiji could feel Yuki's warm and fragrant breath. With such a close distance, they were almost kissing.
Mio? The Demon Lord's daughter was dumbfounded. She gnashed her teeth at the shameless act of Hero Kuudere!
[Rias: Interesting. As someone who has a similar appearance to me. Mio, I support you! Defeat that Kuudere Hero!]
[Sona: I don't think this is the time to support your twin. You think we're watching WWE? Yuki, don't disappoint me.]
[Maria: Mio-sama! I'm Mio-sama's loyal supporter! +1]
[Ravel: These people... What are you guys doing? Can you not interrupt with this line of text? Yuki +1]
[Seekvaira: Is it always like this?]
[Venelana: Fufu. This group is really interesting~]
[Kuroka: Nyahaha! It's always like this, nyaa. You two will get used to it quickly.]
[Koneko: Mio +1]
[Xenovia: Yuki and I often practice swords together +1]
[Irina: Me too! Yuki +1]
[Akeno: Ara Ara. Mio is similar to Rias. Of course we're also good friends +1]
..
..
While the group chat was noisy.
Mio and Yuki pretended not to see it.
"I don't know for sure. But they seem to want to confirm whether or not Mio is dangerous to let live in the human world."
"After everything that happened. Because of her status as the Demon Lord's daughter, Mio is still designated as a level S target that the Hero Clan is wary of."
"Kurumi and I were originally entrusted with keeping watch over her, but hearing our reports that say good things about Mio... The elders don't seem to believe it and still have doubts."
Hero Kuudere said seriously and monotonously as usual. But the distance between her and Eiji's lips was getting closer... The girl seemed to want to peck at the boy's mouth.
However, a hand finally went crazy with jealousy and grabbed the Kuudere Hero's face.
It was Mio, she pushed away Yuki's face.
Although last night they served that boy together, seeing each other kissing and even sex.
The Demon Lord's daughter couldn't stand it when Hero Kuudere wanted to steal her lover's lips in this situation.
She hardly cared what the girl said about her situation.
"...." Eiji looked at the two girls with an interested gaze.
"Mio, what are you doing? I'm having a serious talk with Eiji and you. Don't interrupt me."
"Huh?! You said you were serious? Don't joke with me. I and the others see clearly, you're just a shameless perverted hero!"
Yuki who was called a shameless perverted hero dismissed Mio's hand from her pretty face. Her expression did not change at all and she looked at the crimson-haired girl with a blank stare.
The Kuudere Hero's yellow eyes were dim, looking a little scary but that was how she usually was. Only when she looked at Eiji or her younger sister, her eyes would become as soft as puddles.
"...."
"Wh-What?" The Demon Lord's daughter was slightly intimidated by the girl's gaze and silence.
It was Yuki's fault, she wanted to kiss Eiji when they were having a serious conversation.
'I just want that girl to stop joking around. The other reason is of course, I'm jealous and don't like seeing her kissing Eiji in front of me.'
'It's definitely not my fault...'
It wasn't long and Mio started looking at the light blue haired girl boldly again.
Yuki sighed, she ignored the annoying crimson haired girl and looked at Eiji gently again.
This made the ignored Demon Lord's daughter upset!
Fortunately before they quarreled again, Eiji immediately said: "Those old people are paranoid as usual. And what about me? Why do they want to see me too?"
"That's... I don't know what the other elders' intentions are. But if it's about my father, I've told him what my relationship with you is. As well as Kurumi, Eiji. So, father might want to talk to you since you're his future son-in-law."
Hero Kuudere said that without shame.
If it was another girl like Mio, she would at least blush.
She had apparently already told her father about Eiji eating her and her younger sister.
Yuki's father wouldn't kill him because of that, right? Eiji certainly wasn't afraid of his other father-in-law.
In the original work, he remembered a bit about that man.
And actually he remembered a few things about this plot. But because of the many things he had changed, for example like killing Shiba Kyouichi— he didn't know how this plot would continue.
Of course, Eiji could use his 'Future Insight' to check the rough picture of the future and he did so.
A faint smile appeared on his face.
"Oh? And what if me and Mio refuse to come to their place?"
"Eiji, you don't want to meet my father?"
"It's just an 'if', Yuki. I certainly want to ask your father for his blessing on our relationship even though it's a bit late."
[After all, I have eaten both of his daughters many times before marrying them. Last night Yuki even moaned so loudly.]
This time Yuki's face heated up. There was a tinge of red on her beautiful face that lacked expression.
The girl couldn't help but remember the crazy things they did last night.
Even until now, she still felt the slight sensation that Eiji's big serpant left on her front and back door.
The man's seed was also still left inside her stomach.
If not for the anti-pregnancy magic they often used every time they did it, she would have already gotten pregnant.
Still, for a moment Hero Kuudere was at a loss as to what to answer.
"I've told my father many times about Eiji, but I'm not sure about the other elders. They're actually rather..."
Yuki didn't need to finish her words because Eiji interrupted her. "Some of the old people seem to want to be slapped."
