Incest

why is there so much of it in anime and manga

Izanagi and Izubugugu were siblings.

also, similar to Britain, Japan is also an island with small gene pool. It's in their tradition. Pure blood etc.

Manga you mean cause there hasn't been any incest anime since Oreimo. ;_;

Kiss x sis
Erobambo Sense

>Kiss x sis
You might also want to count Baka na Imouto.
>Erobambino Sensei
I'm going to say no, and you might say yes, but I won't say no again, so just no.

Because it's popular

because
>"muh" taboo subjects

It's the purest form of love.

Taboo always draws interest. And often it follows the same pattern as "childhood friend" where it presents a love interest who is conveniently just there which allows a skipping of anyone needing to take initiative to kick off the relationship.

honestly no idea.
even astroboy had it, its a very common and easy topic to tell shit stories.

>taboo
is there any anime about Shiro Ishii and his Boeing 731?

In eastern cultures, marriage is often an arranged contract designed to preserve family wealth. Keeping it in the family is the safest option.
Eastern cultures also generally lack social trust, personal honor, and religious taboos against deceit. It's best to choose mates with which you have an intimate social connection.
Also, east asian facial features are similar to those of individuals with Down's syndrome, so the genetic disadvantages of inbreeding are somewhat masked.

Shhh nekofag

There is nothing wrong with practicing sexual education with your mom

And the numbers are declining from what I've seen. Good riddance.

kirino is a miracle of the universe

...

Because anime and manga grant the deep seated wishes and desires of mankind. There should be more of it, specifically BR older sister and mother outside erotic material.

people in japan are lonely
the idea of a family member also loving you in a more extreme way is oddly comforting and non threatening

Because no one in Japan has siblings

Because it is the purest form of love

It's a very common fetish that people don't want to admit. Even outside of manga and anime, step sister and step mother porn is pretty loved.

>incest

YES

Because it's hot, but it's true that it's a fetish for guys without sisters.

Why not?

Anime isnt real you autist

>it's true that it's a fetish for guys without sisters
As a guy with a sister with sibling incest ranking far above any other fetish, I can safely that you're talking out of your ass.
