1. Beginning of the mission...

"So yeah...That's how you died" a boy in white shirt and short pants said to a floating ball.

'...So I died when I was found out by that girl husband? Damn...' the soul then sighs and click his tounge.

'So I'm going to hell?' asked the soul, to which the boy shook his head.

"Nope, I will reincarnate you to another world. In that world I want you to continue what you do since in that world, the population there are almost sexless making their population started to decline" the boy then said in an almost shocking way possible,

'What?! how?'

"Well some dude basically creates a virus that makes the libido of the man there lowered...and yeah, they basically become a beta yet won't allow their partner to go search for another one. But...the catch here is that if their partner do find one, the new guy need to take the beta too"

'What the fuck?'

"Ah but don't worry though, the resident of that world are all beautiful! and you will also be one too"

'Fuck! but...but... at least let me set my appearance and choose some powers!'

"Hmm...Fine then since you will be cucking many people and even gods, oh and lastly I forgot to tell you that you will also travels to many kind of universe but don't worry you will be given a Place to let your harem stays there"

A screen then appears in front of the boy and he sees his appearance very well.

A beautiful face as if handcrafted by god himself, a golden brown eyes, a jaw length black hair, a slender body. He then sees his partner and wanted to cry,

'First I want to change the size of my partner...make it like my previous life'

"Woah...Okay, I though you're choosing to make it bigger than 13 inches, but apparently not"

'Well even with 13 inches there's not a lot of girls I can have sex with'

"Fair point"

'Then I want the Incubus Bloodline'

"Umu, nice choice. A bloodline that have an infinite stamina to please an orgy, a dick that can satisfy any girls, and a charm that can melt even the coldest woman or the most devout saintess. Nice one"

'I choose Silver tongue and god tongue'

"I get the silver tongue part, but what about the god tongue?"

'I want to be a cook of course'

"Very well..."

'I choose the Essence of the Blank, Essence of the Adventurer, Essence of the Eroge Harem Protagonist, Essence of the Archmage, Essence of the king, Essence of the Planeswalker, and Essence of the Paradox'

"...Fine...A bit op but hey, you will cuck many people, so why not becoming a strong person? and also there is some benefits will be taken out due to the rule"

'Fine, then I also want this skill, Ultimate Creation'

"Yeah sure, but the only thing you can't make is a soul"

'Fine with me, then I want to be the descendant of the Dragon Goddess of life, Tiamat, which will gives me massive amount of pure Life Force'

"Huh, with a massive amount of pure life force you could basically impregnate everyone, even those who are infertile! Umu, great mind"

'thats all...'

"Good, if you still add more I would immediately vanquish your soul...Sigh..here's a last gift from me" the boy then snaps his finger and a blue panel appears in front of the soul.

'Hooh...So this is the good ol' system eh? very well, no need for the many explanation, just tell me the usage of gacha, summoning and shop please'

<Yes, as the name says Gacha/Summoning basically works the same, whereas Gacha gives the user weapon, skill or items, Summoning allows user to summon a subordinate>

<The three have their own currency, Gacha have their currency called Meta-Essence, Summoning is Tickets which can be gained by mission rewards or Gacha, and lastly shop use what the call as Points, which also can be gained by selling items to the shop or by missions>

'Good, then Rob...I'm ready'

"Very well, I hope you helped repopulating the world again...Farewell boy"

The soul then slowly disintegrating into particle of light before going up, leaving the god alone.

"Sigh...I hope he didnt messed up"

"...Ah screw it, I at least already done my part. Now it's his job to repopulate the world...after that...he could do what the fuck he wants." the boy said while nodding his head, he then swiped the panel and continue to do his work.

...

"Yoshio! wake up!" called out a little girl, a beautiful boy was then awaken by her shouting and sits up slowly, "I'm up Rio! I'm Up! you don't need to shout..." mumbled the boy while wiping his eyes, he then felt that his pants tighten and smiled a little bit before stood up.

When he walked to the mirror he sees the same appearance, a black jaw length hair and a golden brown eyes, also a feminine beautiful face that seems like the god himself is the one who sculpt it. after 13 years living here, he finally unsealed all of his memories and even unlocked all of his power.

Feeling all of his power, he felt his body gotten stronger since it got reconstructed by the

Meaning that his job now...have started.

...

Yoshio then walked toward the bathroom after calming his boner down, and he met with his sister who is the same age as him, and his elder sister who is around 3 years older than him.

"Morning Rio, Morning Nagisa-nee..." Yoshio greeted while yawning, Rio and Nagisa was blushing seeing Yoshio's face, and they thought that they would never be able to get used to his face. and yes, they was shocked when they remember that Yoshio gender is a male.

Rio on the other hand felt something on her crotch raising, Yoshio who noticed it used smirk at it and lets out his Incubus aura a little bit, Rio then felt that her crotch hurt and look that there are a tiny tent stood up.

Nagisa who sees that blushed at it before washing his face quickly and ran away, Rio on the other hand wanted to cry. Yoshio, when he sees that approached her and look at her with worry in his eyes.

"Rio, are you okay?" Yoshio asked her, she then look at Yoshio who is only a few centimeters away from her, and felt that her heart starting to beat faster and there is something coming out from her crotch.

"U-Un! I'm fine Yoshio! just let me go!" she then said in a hurry since she could feel that she is on her limit.

Yoshio then touch her forehead using his to test the temperature, "Hmm...Your head is a little bit hot..."

Rio felt aroused when she was touched by Yoshio and even felt something she never felt before, but Yoshio who notices that and used a magic so that she can't release that feeling.

"Get some rest okay?" Yoshio said while moving away from her, he noticed the shivering tent on Rio's pants and smiled at her.

"...Un..." Rio answered, she then ran toward her room and lock the door. Yoshio on the other hand chuckles a little bit before remembering who she is from his past live.

Kobayashi Rio, or just Rio, is from the doujinshi he read about a futa that cucks her father, Kobayashi Ritsu. heck, even Yoshio have to accepts that his father is actually a beauty and even his mother, Kobayashi Harumi, and his sister, Kobayashi Nagisa, is a also a beauty.

But with his emergence he noticed that, Rio's role have been taken by him and now it was his job to be the man in the house.

"Ah right, I need to go to school!" Yoshio said while slapping his forehead, he then wash his face and change his clothes before using his ability, Observation Haki, to peek at what Rio was doing.

He then see Rio rubbing her crotch to her bed, but still cannot release that pent up feeling. chuckling again, Yoshio knocks on Rio door, Startling her.

"Rio! let's go! we are going to be late!" Yoshio called out, he then walked downstairs and meet with his parents, Ritsu and Harumi.

"Good morning mom, dad!" Yoshio called out, they then look at him with surprised and blushed, Yoshio then remember about his Incubus Aura that he lets out and scratch the back of his head while reigning all the aura again.

"Ahem! G-Good morning Yoshio, where is your sisters?" Ritsu asked Yoshio, Yoshio on the other hand felt weirded by it since even his voice sounds light like a girl.

"Umm...I don't know where Nee-chan is but Rio is in her room, when I test her temperature I felt rhat she's a little warm" Yoshio answered while pondering a little, Ritsu then look at her wife who looked at him back, before sighing and smiled wryly.

"Un, It's fine Yoshio. You just go to school, seems like your sister is having a cold" Harumi said while rubbing her thigh together that her husband didn't even notices.

Yoshio smirked slightly when he sees that and them smiled, "Un, I'll go later" he then eat his breakfast quickly and hugs both of his parents tightly with his aura let out.

"Then Bye!" Yoshio said and ran toward his school, his mother then fell to the ground while his father slumps on the chair, they then look at each other and went to the bathroom. Needless to say, Harumi wasn't satisfied, like she ever had.

"What? are you done already?" Harumi asked with dissapointment, Ritsu could only nodded and felt that his pent up feeling still couldn't be let out even though usually just 1 round could let his feeling out.

He then noticed that he was going to be late, "Oh no!" Ritsu said then kiss his wife before going to work, Harumi could only sighed in frustration with her husband 4 second heroism.

Rio on the other hand just slept on her bed, not hearing the commotion in the bathroom.

Nagisa also already went to school since she was scared of her current feeling.

...

In the classroom,

"Good morning~" Yoshio called out, the people in the room then smiled brightly at him, especially the girls.

"Yoshio-kun! I've read the novel you told me, and man you're right, that stuff is the best!" a boy said to Yoshio.

"Right~ I told you 'Oh my Goddess!' is a good read!" Yoshio the grins at him, the people who sees his face felt warmth in their heart.

They remember the first year the met with Yoshio, and was shocked when they knew that his gender is a male. The boys was the one who got shocked the most, since again, Yoshio appearance was too amazing for the people.

"Ah right, Yoshio-kun, Your fiancées are looking for you yesterday" The boy said, hearing that Yoshio could only smiled wryly at it.

He remember about 2 of his friends that he made in elementary school, one he saved from bullying due to her rich upbringing and the other he befriended without minding about her attitude, and finally they confessed to him at the same time and promised to marry him.

Knowing that they're still a kid Yoshio just accept it since he thought that it was only a kid's whim. But he was wrong, even after 6 years they were still wanting to marry him, and with Japan now have lower birthrate and all the Spacequake happening, they launched a program called "Hare-kon" which basically allows or even told the people to have more that 1 wife.

Back to the topic, And yes Yoshio knew that the world he lived in is a mixed with a few other works and the 2 that gains his attention are...

Well you will know it later.

Anyway Yoshio then walked into the classroom and sits on his chair and begin the day as usual, being the smartest kid in the school and even create a thesis about technology.

"Good morning~" said a teacher while walking toward the room.

...

School passed and Yoshio then walked back home, he felt that this peace is also something that he likes.

He have lived his life as he wanted for this past 13 years and even gained many fiancée in name, And unknown to him, tomorrow will be the day his normal life changed.
