Heya. Another one-shot. I explained before that I was going to write a series of one-shots focusing in two girls per chapter. But I forgot about that and started that Mahouka fanfic instead. I also said that I was only going to do the fanfic after I finish the Mahouka one. This is a different idea that I had. When I wrote the Demon King Brides, Solami hadn't been introduced yet so she was not included in that story. But since we know her now (Volume 11) I decided to include her in a special chapter. Noah too, I think she has potential to become part of the harem but.. she really gives that vibe, you know, that character-that-will-become-an-enemy-one-day vibe. But nonetheless, if she becomes an enemy, I feel like she could fall for Diablo after the fight or something. Just my guess though.

Oh, just to make it clear, about the fanfic made of one-shots, the duo of girls per chapter will be:

Rem & Shera (obviously)

Krem & Edelgard (also obvious)

Sylvie & Mei (since they both live in the same city)

Alicia & Lumachina (mostly for the contrast between the madness and the purity)

Lamnites & Rafflesia (both are the seductive and kinda shameless type)

Sasala & Rose (...they kinda became the rest in this case)

Solami has no one for the moment sadly.

I don't own anything.

Extra chapter - Solami

"What exactly are you planning?"

"Don't be so cold to your onee-san, Diablo-kun. I just wanted to get to know you better and maybe get myself a husband while I'm at it."

"This is what I meant when I said 'planning'!"

Diablo was laying down on his bed when someone suddenly sneaked in his sheets. More accurately, he felt something soft and a little heavy pressing on him and when he reached out his hand, that something let out a moan. Then, Diablo realised that that something was actually someone. That someone just happened to be Solami, Ren's aunt and the assistant instructor of the Gado style. She is a fistfighter on the level of a demon lord, so why is someone like that sneaking in Diablo's bed in the nude? The thing is...

"Heey, Diablo-kun. It's rude to space out in front of a lady, you know?"

"...I wasn't really spacing out."

(I was about to though.)

Rather than spacing out, escaping reality was more fitting. Thanks to his beloved wives, Diablo managed to build some self-confidence out of his demon lord acting but Solami was a special kind of "bad". It was not the first time Diablo dealt with "aggressive" women, after all, Lamnites and Rafflesia were both carnivores, with Lamnites being quite selfish and Rafflesia being more willing to accommodate Diablo's feelings. If there was one thing they all had in common, it was the fact that they all seemed used to getting what they wanted. Lamnites with seduction and monetary resources, Rafflesia with her charms, and Solami with seduction AND strength.

Even if Lamnites was indeed powerful as a magic gunner, she would use threats before actually shooting. Solami would use her strength regardless of wherever she was threatening someone or not. That made her a little harder to deal with since if the one dealing with her was not strong enough, he would get hurt regardless of Solami's intentions.

"Come on, it's fine, right? It is, isn't it?"

"Why would this even be fine?"

"I mean, Diablo-kun already has twelve girls serving him so I thought you wouldn't mind one more."

"...It was something brought out of necessity. I already explained."

"Even so, the more the merrier, right? I mean, I have a lot of confidence in my technique and I'm bigger than Rem-chan. I'm sure I could give you a very nice time."

"You… Do you even care about the fact that you are hitting on your niece's husband?"

"Ehhh… I mean, even if you are Rem-chan's husband, it's not like you can't be mine as well, right? It's only natural to go for a good man when you find one."

"There are so many wrong things with what you said that I don't even know where to start!"

Leaving aside the fact that Diablo was a polygamist, it's not like he just grabbed whoever he could find. He powered up from defeating the Great Demon Lord Modinalaam and realised that his magic had grown too strong. If he wasn't careful, he might kill or seriously injure someone whenever he casted magic. Gathering his brides was something of a countermeasure to divide his power among them, lowering the risk and strengthening everyone at the same time. While Diablo was still much stronger than he was before fighting Modinalaam, it was already at a safe level. To put it simply, he had no actual need to gather more girls.

"I was under the impression that Diablo-kun was someone who would not hesitate to enjoy a good time with a beautiful girl."

"I understand how my situation looks but that impression is mistaken."

"Come on, isn't it fine? If you can't do it for lust, at least do it for me."

"How does that work for you?"

"In our family, we value strength more than anything else. Diablo-kun is not only famous for defeating the Great Demon Lord that attacked Faltra City but you also proved yourself against me just yesterday didn't you?"

"Well..."

As a matter of fact, Diablo had a duel against Solami just the day before. This also showed how things did not go according to plan. Originally, Diablo came to this Caliture City to greet, or rather, say goodbye to Rem's relatives. Life was all good, what with his brides, Modinalaam finally slayed and his adventure life went back to normal. Then, Rem revealed that she actually still had living relatives and they were part of the Gado style. They were powerful fistfighters that used advanced techniques and, according to Rem, they were something akin to a yakuza family. Rem wished to just report her marriage and then cut ties with them for real so Diablo and Shera followed her here.

Rose and Sylvie were supposed to accompany them but Sylvie was just finishing her preparations to pass on the mantle of guildmaster to Emile and Rose had gone back to the dungeon to grab some items that Diablo asked for. The problem came when Diablo noticed that Rem's aunt, Solami, was way stronger than he expected and she also noticed how strong Diablo was. Diablo recognized Solami as someone who managed to surpass level 150 and had the power worthy of a demon lord. If it weren't for his recent power up, he wasn't sure if he would have won. In the end, Diablo was recognized since he defeated Solami, the strongest in the city, and while the other disciples hoped for Rem to stay and train her martial arts, they didn't seem intent on forcing her. Or at least, that was supposed to be the end. They were all invited to spend a few days there and Diablo accepted since he wished to rest after his duel and he was curious about their martial arts. Rem and Shera decided to take a look in the city and Diablo decided to just rest on the bed when Solami sneaked in and brought about the current situation.

"Isn't it risky to bring anyone in as long as they are strong?"

"We do have some standards. And we don't usually use this method, I mean, it's not everyday that we see someone as strong as Diablo-kun."

"...I guess that's true."

Indeed, a level 150 player being isekai'd to this world shouldn't be an everyday occurrence.

"But even so, I'm a magician. Isn't that quite different from the Gado style?"

"But you were interested in learning our techniques earlier, weren't you? And it's not like we strictly prohibit our disciples from using anything aside from martial arts."

"Even so, there is no reason for me to go through with it."

"Reason, huh? Are you perhaps talking about mutual feelings? Was that the case with your wives?"

"Well, that's..."

Sure, right now Diablo loved all of them and they all loved him but was that really the case from the start? He could somewhat tell that Shera, Rem, Lumachina and Rose loved him even before but that wasn't necessarily the case with everyone. Mei, Sylvie and Sasala had something more akin to a crush on him rather than actual love. Edelgard and Alicia had other factors involved (loyalty towards Krem and madness, respectively). Lamnites and Rafflesia took a fancy to him but their interest also had second intentions. Krem was… well, somewhere between Shera's group and Sylvie's group on this one.

But even so, could Diablo really do this? Did this count as a betrayal or unfaithfulness of some sorts? Rem and Rose were definitely not going to be happy and Lumahina might get sad but the others probably won't mind. Lamnites and Rafflesia could even say "as expected". Thinking this way, it all falls down to him. Diablo admitted that Solami was a beautiful pantherian with a voluptuous body but her standards were a problem, more so than her personality. During his fight against her, they also talked and Solami made it clear that, even if she loves Rem as her niece, she would still kill her if she was hired to do so. If Solami is hired for a job, even if it involves the deaths of someone close to her or a huge number of innocents, Salami will still do it if it's a job she accepted.

"As expected, I really ca-! Uaah!"

"Fufufu! Got you by surprise."

Diablo was about to deny Solami when she suddenly licked his ear, catching him off guard. When he thought about it, they were still in the same position as before, Diablo still laying in his bed with Solami still on top of him. She wasn't just straddling him, her boobs were touching his chest and face was centimeters away from his. He could feel her breath on his face the entire time as well.

"Diablo-kun, I'm not sure how you came to marry twelve girls but I don't think my situation is that different. I do like you a fair amount."

"...Hah?"

"Is it that hard to believe? So cruel, even though you said those things to me. Your hot thing also hit me so hard..."

"Wait a second! I never did such a thing!"

"Do you really not remember? Come on, it was just yesterday."

"Yesterday? Wait..."

~Flashback to the duel~

"Would you really kill Rem for just a job?!"

"...It's not like I like it but it's the way it is."

Diablo and Solami were locked in a stalemate. Solami approached him for a punch and Diablo blocked it with a magic shield. There were sparks flying everywhere from the collision between Solami's martial art that made her fist look like a thrust from a spear and Diablo's shield. Their fight had already destroyed almost everything around them, even the expectators had to keep their distance so as to not get involved.

"I will not accept it!"

"What?"

"I'm saying that I, Demon Lord Diablo, will not accept such a ridiculous way of thinking! You have such power and yet why do you subject yourself to such a pathetic rule?!"

Diablo created a mine right under Solami and leapt backwards to dodge the explosion, creating some distance between them. They locked eyes, still talking but not making any moves.

"...That's just the way our family has always been."

"And you just lowered your head?! Resist it! Rebel against it! Make your own rules!"

"...Diablo-kun, I'm just an individual, just another from our family. Am I supposed to just change everything by my own will? Change what remained within our family for generations?"

Though Solami was still on guard and her eyes remained sharp, some sadness was visible in them. Diablo on the other hand, was furious.

"You can do it!"

"Eh?"

"You are someone that I personally acknowledged as a demon lord-level opponent so you have to do it! There's no one to stop you!"

"...But..."

"If you still insist you can't, then I will do it! I won't let you ever fight against Rem and I won't let Rem grief over your death! I swear on my name!"

"Diablo-kun..."

Diablo then used his White Nova and Solami tried to intercept it with her Kikouha. The two attacks collided and everything went white.

When the brightness settled down, Solami was on the ground. Though she was still in one piece, she was clearly not in condition to keep fighting. Diablo approached with steady steps.

"You...win...Diablo-kun…...Please...keep Rem-chan….safe…."

"You idiot. If you really want it, then do it yourself."

Diablo grabbed a potion and sprinkled it over Solami. Her wounds quickly closed and she found out that she could stand again.

"E-Eh? But why? If you do this then I..."

Diablo grabbed Solami by the front of her dress, or what was left of it anyway, glared at her in the eye and said...

"I will fight you as many times as it takes for you to understand. Rem made her choice to leave your family so you can make your choice as well. Choices are not things that you get from others, they are things that you create yourself."

"Diablo-kun…."

~Flashback end~

"...And that was it."

"...I didn't do anything impressive."

(...I'm guessing that the hot thing was one of my spells? I did fire a few that burned her a little, though she blocked them quite well with her defensive martial arts. And she just had to make it sound weird, didn't she?)

"Shrugging off the entire tradition from our family is not something small."

"And what does that have to do with our actions now?"

"How to start? A handsome strong guy defeated me and gave me an awe-inspiring speech to change my ways. Since my niece married him by her own will, there's no way he is a scumbag pretending to be a gentleman and he even accepts polygamy. Everything points that I have a chance as well. Or, with your own words, I have a 'choice' as well."

"..."

(Speech, huh? It wasn't really awe-inspiring but I guess it was quite good coming from a former NEET and gamer. Go, me. But she had to corner me with my own words right towards the end.)

"To be honest, that moment when you brought your face in front of mine and told me to make my stand, my heart skipped a beat. When I first saw your serious face I thought you weren't my type at all but now… You are the perfect man for me, Diablo-kun."

"...!"

Solami was always smiling, that just highlighted her confidence and playfulness. But her smile right now was different. It was a beautiful smile, one that truly showed her happiness. Diablo found himself once again caught by surprise.

"Though if you still can't accept me as your bride, then at least take me as your lover."

"L-Lover?!"

"Come on, it's fine, right?"

"How is that fine?!"

"I mean, with so many wives, you must want someone to wash away your tiredness. A lover is just the perfect role for that!"

"That's just for cheating husbands, isn't it?!"

"By the way, I already spoke with Rem-chan."

"You what?!"

"I explained everything to her. She didn't seem happy but I might have moved her heart with my sincerity since she said that I could try seducing you."

"So Rem and Shera were out..."

"...because we planned for it."

"..."

(I'm not sure how I feel about all this. I'm not sure if Rem was expecting me to refuse Solami or if she actually wants Solami to have a chance.)

Rem clearly disliked her family but Diablo knew that she still cared for Solami. If Solami really had a change of heart and tried to have a shot at being family for real, Rem might just, in a one-in-a-million chance, decide to give Solami her approval.

"So, Diablo-kun, please. Allow me to show my gratitude to you."

Solami then closed her eyes and slowly approached Diablo's face. She was clearly moving slowly to give him time to either dodge or stop her. Yet, he remained still. Diablo felt that since Solami and Rem showed their feelings, he had to respond in kind. But that small doubt still persisted inside of him and as a result…

(Her lips are so soft…..but what is this?)

Diablo accepted Solami's kiss but he felt something strange. When he turned the others into his brides, he felt their connection forming. His power was shared among them and he felt their bond but the bond this time felt a little different. Diablo couldn't quite put his hand into what it was but something was clearly not the same.

(Was it because I still had some doubts? Was the bond not properly established? Or could it be… She really became my lover?!)

The marriage system was not implanted in Cross Reverie by the time Diablo came to this world so he wasn't completely sure but it seemed to also have a lover feature. Diablo was not sure how to explain this but he guessed that for now everything was settled.

"Hm… Diablo-kun, I heard that you have plenty of experience so… we are not stopping here."

"...quite an eager lover, huh?"

"Lover…. So that strange feeling really was our bond. And I became your lover, was it deliberate?"

"No, I… also had no idea this was possible."

"Then, I'm special among your girls, right?"

"...That's a way of putting it."

"Then, let's have a special night, ok?"

Diablo was not nervous anymore thanks to his time with his brides, though it still felt strange to do this with someone so similar to Rem face-wise but similar to Shera body-wise. Diablo never imagined that after getting summoned to this world he would get married, much less get a lover.

When Rem came back, she angrily demanded that Diablo also spent the night with her and Shera. And Solami did the same in return. It took some time before Diablo managed to sleep at night.
