Chapter 1: It all begins with wishes.

In the deeps of the void, another soul was wandering lost, and unconscious. This scene was a quite common one in this plane of existence. Eventually, the soul reached a different area where it just laid down and stopped. Soon it gained consciousness and began panicking.

"Ahhhhh!!!... Wait? Where am I?... Did I really die?" It asked itself questions as the recollection of the events that occurred prior reached it one by one.

"This is why you shouldn't go camping... *sigh*, my bad luck killed me. Well, I was already out of it with life anyway..." The soul felt that the events that led to its death were unfair and tried to lie to itself about not caring, but in the end, it was very dissatisfied with this ending.

"I had so much to live for, all my hundreds of figures will now be defiled by the hands of those unholy losers... At least reincarnate me will ya!" Its complaints soon became an unreasonable request, but sometimes the universe gives us exactly what we ask for, whether it's a good thing or not, that's a case for case discussion.

"Fine! I'll reincarnate you, damn it, can't I even have a second without having to reincarnate some unsatisfied mortal! I mean, you already had your shot at life.... Sorry, I'm just stressed from work, I guess it gets to you after a few million years... and I still have to do this for billions of years before I can retire." A being with no body appeared as a sphere of light, then begun complaining about its life and work problems to a client, this smells of demotion and even maybe unemployment.

"I'm sorry for you, but I just died and I'm having my problems right now. Also, just who or what are you?" The soul asked while trying to be nice about it since it was also somewhat aware of how taxing work can be.

"Apologies, I'm the Being in charge of the reincarnation, you can call me Serenity or just do what most people do and call me God, Rob or Isekai God/Goddess and so on." Serenity introduced herself and then made a remark that showed how angry at the mortals that didn't care about using her name she was.

"I'm sorry that's your situation Serenity, oh! Also, I'm Leonas Kaori and so, what now? How do I get reincarnated?" Leonas introduced himself as he tried to sympathize with Serenity, but he was still curious about reincarnation, after all, he read too many stories that involved it.

"It's very easy, I'm sure you read it in some novel or fanfic or whatever by now. All you have to do is make 8 wishes. I'll make them come true, well, if the wises are too unreasonable, it's uncertain to what extent they will be complete, so be careful." Serenity explained calmly and smoothly, it's obvious she was used to doing this.

"Hm... first, can I call you Sera? And as for the wishes... The first would be something among the lines of true immortality, I feel like that would be pretty decent, what do you think?" Leonas started explaining what he wants as a first wish but then decided to ask for a second opinion.

"Oh! Yes please do call me that! As for your wish... If you really want my opinion, I think adaptive immortality is better all things considered, but it's also vastly more painful." Sera spoke her mind and started her opinion.

"Great, you can call me Leo. Now, what exactly is adaptive immortality?" Leonas asked interested in this new possibility.

"In essence, it's immortality, but you die to become immune to that type of death... If I had to give an example, I would say the ability to return by death of Subaru Natsuki is similar to it. It also has two other main functions aside from that, one, of course, you no longer age after reaching maturity, and two, everytime you 'die' you'll experience something akin to a zenkai boost." Sera explained while giving examples that made it much easier for Leonas to get the full picture.

"You got me with the zenkai boost thing. I'll take adaptive immortality as my first wish. Moving on to the second wish, I want a custom system that will grow stronger with time and that will be loyal and respond only to me." Leonas proceed to make the first and second wishes calmly.

"Done and done, what more?" Sera said in response.

"Humm... I want to take infinite luck as my third wish. What do you think? Will it work?" Leonas asks Sera since she's proven to know what she's doing.

"I would say that it's best if you ask for inconsequential infinite luck, that way you're luck will only affect you and not others at least not directly. If you do so, you won't be as limited as if you just asked for infinite luck, since things like your enemy slipping and just dying will no longer come to play, I believe your wish will be stronger and it will be more beneficial on the long run." Sera once again explained her reasoning.

"Good, then my third wish is inconsequential infinite luck. As for the fourth wish, I want true adaptability, so that my body, soul, mind, etc will be able to always adapt." Leonas made the third and fourth wishes happily.

"Keep them coming!" Sera said playfully as she was happy that after so long someone was listening to her and valuing her opinion.

"The fifth wish is for a Harem king dimension that belongs to me solely and where I make the rules, it also has to be undetectable and connected to my system." Leonas said his fifth wish having into consideration that is asking too much might backfire.

"That can be done, as for the undetectable part, I can't guaranty that, but it can be very well hidden to the point higher being wouldn't easily find it. Is that ok?" Sera said with a slightly troubled voice.

"No problem, go on with the wish, I already expected it to be that way. For the sixth wish, I want 5 personalized growth-type weapons, namely 2 swords, 2 chains with spear tips, and a formless weapon. All able to develop special abilities as they grow with me." Leonas conformed the fifth wish and made the sixth.

"Nice! That's the spirit, you are free to fire your last two wishes." Sera seemed to lighten up seeing Leonas wasn't bother his wish wasn't exactly what he wanted.

"My seventh wish is to remodel or remake myself, choosing my race and so on, first I want for my race to be an ever-evolving life from, my base or original form being that of an energy life form but not just any energy life form, I want to be made from the purest and most powerful form of energy, then for my physical form, I want to be a void slime if you want an example of how I want it to look, something like how Rimuru Tempest looks like as a slime but taking into account my void characteristics and now my human or humanoid form I want it to be a half-dragon half-demon half-angel of highest tier that looks human but with some characteristics of all those and they're respective bloodlines, also I want this form to look androgenous and be a Futa. Now lastly but not least important, for my spiritual/soul form, I want it to have characteristics of my other three forms and to look like some kind of celestial demonic avatar." Leonas finally let his internal desires slip and even had his voice sound somewhat perverse as he announced his seventh wish.

".... If you had gone on for a bit more I would have no choice but to tell that it costs 2 wishes, but since you didn't, you still have your last wish... I was going to say you're the most normal I've met but that no longer applies even though you're still very far from the worse I've seen." Sera was troubled while saying, not knowing exactly what to say after that last wish.

"Hahaha, then my eighth wish might stun you a bit. For my last wish, I want to ask you to come and serve under me, not only to be my assistant and help from my harem dimension where I will give you the best treatment I possibly can within reason and also for you to be the manager of my soon to be harem as well as a 50% chance of becoming my first and only Queen. I'll have many wives but only one Queen. So, what do you say?" Leonas made his eighth wish with confidence and softness.

This utterly shocked Sera and created a long silence.

"I- I-... This is so sudden, I've heard rumors of one of the people who had my job getting taken once before, but I never thought I would get such an offer... Can I think about this for a bit? It just changes everything and I think I need some time to digest this and ponder on it." Sera was speechless for quite some time and then finally mustered the courage to ask for some time to think, after all this was no different than asking someone to leave all of their life behind to run away with you, probably because it's what's happening.

"You can take your time, it's not like I have anywhere to go or to be. No need to worry, It'll be fine even if you refuse." Leonas was calm and rather in a great mood anyway in the end if Sera refuses, he can always ask for another thing and he already has something in mind, so no worries.

He's not even worried about the possibility of not getting his wish back, cause he already asked for all the important stuff, so it's fine either way.

Like that Leonas had to wait in the void for God knows how long, but her answer did come.

"I've made my decision. I thought very carefully about and...." Sera was nervous as she hesitated to give her answer.

Leonas didn't say anything and simply decided to let her make her own choice, after all, it's not good to pressure people when they are making life-changing decisions.

".....I'll go with you!" Sera made her decision after much consideration.

She had concluded that she wasn't happy being in charge of taking the wishes of mortals while her own had to die inside of her for billions of years, who would want such a life? After talking to some beings she knew and what was left of her family, she made her choice to go for a more adventurous and risky life working for Leonas, It's not like she has to worry that much as he is immortal and she's also curious about what this odd man that decided to live as a woman with one extra genitalia is going to cause in the future, she had always been a dreamer and was told that would lead her a dangerous path someday, it seems that day had come.

"Great! From now on, where am I getting reincarnated anyway?" Only then did Leonas remember to ask.

"Oh, that's random. We are going to an anime world tho. Brace yourself as your last wish is getting authorized and we will so get transported." Sera answered with excitement brewing in her voice.

"I guess my Harem King legend will start here, I'll be the greatest of them all!! Hahaha!" Leonas also carried excitement in his voice.

Soon both of them were enveloped by a powerful light and were nowhere to be seen in the void.

....

In a forest with not so dense vegetation, a sphere of light appeared in tin air floating untouched, then it started shaking and changing until it became a blue blob of slime with dark engravings with a white outline as if tattoos on its body. That didn't last long either and it began shaking again and this time its form increased in size as it took human shape.

In a few seconds what could be seen, was a young person with long purple hair, a girly face, eyes, but overall it was hard to say. The body was slender and short only reaching 1,65m(165cm/5'4) of height, the arms aren't strong or buff, the flat stomach having the semblance of a six-pack but nothing too noticeable. The legs have slightly thick thighs when compared to the rest of the body, but with such a slender body they were look lacking in anyone else, while the feet are delicate and princess not angel-like. The body is overall symmetrical and petite, well, almost all of it. In between the legs hangs a sleeping dragon with the might to destroy lives and marriages alike, as it guards the entrance to the sacred palace that hides behind it. Then much higher above are the last perpetrators of the symmetry, two mountains stand tall and round, and just looking one would wonder how much back pain someone with such a petite body would get from carrying them.

"It seems I have arrived. I wonder which world I ended up in, not that it matters. I'll conquer any world and take the beauties along the way!" Leonas declared as he got used to the new body, the voice coming out of his mouth just as gender-neutral as he looks, or should it be said she looks? Oh well, in the end, it seems Leonas still sees himself as a guy for some reason.

[Connecting system to host.... Process complete, welcome master Leonas.] A female slightly mechanical voice could be heard in Leonas' mind.

[Hey! Leo! Can you hear me?! Hey!!!] Sera's voice was heard as soon as the system finished connecting to him.

"You don't have to shout, the system just connected and I can hear you. Are you already in the harem dimension?" Leonas calmly answered then proceeded to ask a question of his own.

[Yes! This place is really fancy! There's a whole mansion with a large garden oh and maids! They all look like adorable dolls! It makes me want to smooch them all!! I knew I made the right decision in following you! All those who called me naive and impulsive! I am the last one to laugh! Hahaha!] Sera was no longer trying to seem somewhat professional so, her truer self was showing.

"I thought it would be empty at first, but by your description, it seems they read my mind and made look how I wanted it, I'll have to look at it later. Now, Sera can you find out what world I'm in?" Leonas asks after deducing the reason why the harem world was already occupied by the mansion of his dreams and fantasies.

[If you give me some authority over the system, I can easily discover... OMG! Is that a 7 layer red velvet cake!? I'm in heaven! Best decision ever!!] Sera immediately answered then got distracted by cake.

"Hahaha!"

Leonas couldn't help laughing at her cuteness, she's much more relaxed than back there, and he was happy she wasn't regretting coming with him.

"Ok, system give Sera vice-administer authority and her with her work." Leonas ordered the system rather calmly.

[Yes, master Leonas.]

[System request! The system would like to request a name for itself. Would you like to give the system a name? Y/N]

Leonas picked yes and immediately began thinking of what to name the system.

"After thinking for a bit, I've decided to name you Fidelis Kaori and for short I'll call you Fide. So, welcome to the family." Leonas says with a smile and with his current looks, it would cause many to die of diabetes.

[It is an honor, master Leonas!] Fide seemed happy with the name and overjoyed to be welcomed and accepted by its master.

[No fair! I also want to be part of the family, aren't I supposed to be your assistant and you even had the guts to semi-propose to me. Now you're treating the system better than me.] Sera started fake crying, making Leonas shake his head.

"Fine, you're Serenity Kaori, my first soon-to-be wife. If you want the title of Queen, earn it." Leonas said not really bothered, for him this development doesn't really go out of his plans, actually quite the opposite.

[Master Leonas, I must apologize in advance, but I must correct your statement, as the first to receive the Kaori surname, I'm better classified as the first wife.] Fide not being very well aware of emotions yet, couldn't catch on to the fact Sera wasn't being serious and that Leonas just used this chance to plant the seed of the idea to let it grow on its own.

"Of course, Fide, you're the best girl." Leonas said in response with a smile.

[Processing overload!... Initiating cooling process... Process completed. I am very thankful for your compliment master Leonas.] Fide got flustered in her own way then thanked Leonas.

"Sera, do you know where and when I am yet?" Leonas asked wanting to know so he can start planning how he's going to move.

[Yup, and I think you're going to like this.] Sera said in a relaxed tone then Leonas could hear some munching, she was definitely eating.

Leonas couldn't help but think (What a weird start I have.)
