The same reason why lolis are 2000 years old or 90% of the females are 14 (age of consent in Japan) .

To make the wincest more palatable for normies.

Wait they're NBR????

Because it keeps the spirit of incest which some have a fetish for, but isn't actual incest. It's like vegetarian meat: it looks like meat, it tastes like meat (if you got a good brand), but it ain't meat.

so they can justify incest

thats a win win for me

so they can have unprotected sex.

did you not watch the show

I did but like 5 years ago. I thought they were blood

to prevent incest shit

That's not a twist though, it's in the prologue.

It never tastes like real meat. Same with the fake incest.

Coward authors that don't have the guts to try and circumvent the government laws and have actual incest on it.

i thought it was 16

It's 13 as long as actual people aren't involved

>Plot twist
Maybe if you're a speedreader

Incest is Wincest

So it's not as morally reprehensible for them to fug and make babies.

to take out the fun

it's 18 in practice everywhere in japan

You're forgetting if the parents agree to it.

>She tried to rape him (in a 18yo body) but Jibril appears
>He pass his age to Jibril
>Now he is under age
He don´t want to have sex with her
>Later a harem of robots appears
>He don´t want to make sex with any of the robots
He just want to became a wizard
>He have a child with the princess of the sea
???

Princess was an accident on his part/rape. So it's not like it doesnt apply to the rest.

How does that work

You can only bre-I mean make love to your sister if you aren't blood related, user. Otherwise you sully glorius nippon's gene po- I mean otherwise it's morally wrong. Have babies with people who aren't related to you
