Imouto or Nee-san?

Imouto or Nee-san?

Both

As someone with no actual sisters, it's a hard call I think.

I can see the appeal as both, but at the end of the day, I'm a man and would prefer a more submissive girl I felt the need to protect, and it's more likely to be a younger sister, than an older one.

I was an imouto man growing up

But having been wisened by the passing of time I have come to conclude that Nee-san is definitively superior

Both

Younger imoutos.

The better imoutos.

When was this? Is it from Korean Zombie?

Despite growing up with a disgusting older sister, I believe nee-sans are infinitely superior to imouto.

It's in the filename
