"Welcome to afterlife, Satou-san and his family. I'm Eris, Goddess of fortune. It's maybe short but the three of you, has died."

The three of them open their eyes and they see a silver hair woman who is sitting in the chair with sorrowful expression.

"A-are you an angel?"ask younger one, seem to be a kid.

"No, I'm a goddess of fortune, Eris."

"…Then can you explain why we're here?"ask the women, seem to be a mother.

"Simply enough, you three has died because car incident."

"Ah, I remember now! I'm avoiding that girl who is careless crossing the street!"said the man, seem to be the father in this family. "So… is that girl all right?"

"Don't need to be worry, she is all right but maybe she will be more becareful next time after seeing a car accident."

"Fuh… that's good to hear… she sure will be more becareful next time, sure?"

"Em… Eris-san… right?"ask younger one and Eris nod for answer his simple question, "What will happen to us?"

"Actually, the younger is given in two option… option one, going to heaven… option two, being reincarnated in fantasy world with magic in order to stop the demon king and their army… more likely an rpg game in middle-age world, if you choose option two then I will give you one of your wish there… for the older one… that's another matter until this kid decide…"

"I'm NOT a kid!"scream the younger one.

"So… we're going to heaven?"ask the father.

"Not sure, heaven rule said the younger one must choose first before we continue this talk to another soul."

"… I'm kinda curious, what's our first son choosing after he died because that embarrassing incident?"ask the moher.

"Oh yeah, I remember aniki love games… especially rpg… I'm sure he will pick option two…"said the younger one.

"That's being said… Eris-sama, do you know someone named 'Satou Kazuma'? He's our son and we like to know what he choose and how he's doing there?"ask the father.

"Kazuma-san? Yes, I know him… he's choosing fantasy world and bring a goddess with him… he's doing well and recently I heard he's developing a relationship with one of his companion…"

"Developing relationship? That sound kinda lil suspicious there… I want to ask is he still a hikikomori and a NEET?"ask the mother.

"I can say yes and no… sure, he's lazy… but he's doing great in business and quest if he want to…"

"It's bother me a little… how much is his companion? Is it mixed gender or all boy?"ask the younger one.

"Hm, he has 3 companion… mixed if you add Kazuma-san there because the three of them all female…"

"A HAREM SITUATION!?"scream all of them except Eris.

"This is bad... what if our son commit a crime, Honey!?"scream the mother.

"I think that too!? For now we must go to that world!?"scream the father.

"Eris-san! I have decided go to the world where aniki live!?"scream the younger one.

"Eh? Sure…" a bunch of card appear in front of the younger one, "Just pick one divine relic that might interest you, but if you have anything else in mind just sa-"

"I choose my family, otou-san and okaa-san!"Eris word interrupted by the younger one.

"That's quick, but why are you pick your family over a divine relic?"ask Eris

"BECAUSE WE'RE WANT TO MEET KAZUMA!? WHAT ELSE!?"said the three of them in the same time.

"O…. k…. because the older also will be there, the two of you want anything in mind what you want to bring there?"

"Hm… what do we need there, Honey?"ask the mother.

"I don't know anything else except money and learning language there…"said the father.

"Don't worry about money, I will provide the three of you some amount of money that can live for a month… about language, you will instantly know it when you're arrived in that world…"said Eris.

"So it's like the language there is infuse to our brain?"ask the younger one.

"More like that… don't worry, it's safe… btw, Kazuma-san mother and father… do you have anything in mind what to bring there?"

"We don't know, we're not a gamer…"x2

"Maybe I will suggest for my parents, Eris-san… Because it's in middle age, gadget is not present there right?"said the younger one.

"For someone who's live in that world since birth, none of them even know what gadget is… just summoned hero who know what is it…"said Eris.

"Just summoned hero? Is aniki and my family count?"ask the younger one which is Eris reply with nod, "Whatever… otou-san, okaa-san, how about we bring a laptop and a handphone there?"

"But we will going to middle age world, how we will charge it?"ask the father.

"Then charge it with mana, we don't need electricity anymore… and we will going to the world with a real magic, not a trick one but one that can't explain by science… that's why it's called fantasy…"

"But the content will be none…"said the mother.

"Then connect it to our original world, can you do it Eris-san?"the younger one question is answered after seeing Eris nod.

"I can do that, but you can't call or send something to your original world… you just can download, receive, and read from your original world… Hope you don't mind…"

"We don't mind…"said the three in unison.

"Ok…"

Suddenly there's something in the parents hand, both of them hold a handphone and a laptop, there's also a bag for laptop.

"Cool… just snap and it's suddenly appear…"comment the younger one.

"Thanks… btw, here's the money you three need for 1 month…"said Eris while give little bag full of coin to the father.

"Er… are you sure?"ask the father.

"Just take it, it's usual for me to give a little money for someone who want going to fantasy world…"

"Then I take it, thanks a lot."

"You're welcome!"said Eris with smile.

"Hmm, what's glowing thing around us Eris-san?"ask the younger one.

"Wah! we're floating!"scream the mother.

"Satou-san and his family, you all will be sent to another world now and became one of heroes that will defeat demon king… but it's all up to you for fight or not… but someone who's able defeating demon king will receive reward from gods, any wish will be granted."

"A reward that sound ap-"

Before the younger one end his speak, the three of them already disappeared there and teleported to fantasy world, in Axel exactly.
