I'm playing some more Valkyria Chronicles 2, and man is this game just a tour de force of every bad anime trope you could ever think of. This time it's that old chestnut, romantic brother-sister incest!
Two of your class/squadmates are brother and sister, with a timid shy younger brother and a strict, unhealthily protective older sister. As you progress in the younger brother's personal storyline, you discover that he wants to become a strong man to protect and impress "the woman he loves," prompting an immediate groan from me. Then I thought I should wait. Maybe I just had my mind in the gutter and that wasn't what they were going for-
Nah. Upon finishing his personal mission it turns out that was precisely what they were going for. Don't worry though, they're not related by blood so it's okay!!!!
That just makes it even more creepy, but it gets worse
Only the brother knows they're adopted siblings and he still intends to pursue her romantically anyway 
Also get the fuck out of here with that real/not real siblings shit, these two were clearly brought up as siblings from childhood. The cherry on top is that finishing the sister's personal mission confirms she just sees him as a little brother.
Somehow the worst part is the himbo protagonist just giving the guy a thumbs up after hearing this extremely weird and fucked up confession and going gee, that's not something you hear everyday but I hope you it works out for you bro! 
instead of calling him a weirdo
Why why why 
do Japanese writers keep returning to this same incest trope over and over again. You're telling me you can't have a single gay relationship in this game but you had to have a sister fucker with just enough convoluted asterisks to make it technically okay (still not okay)
In Game of Thrones and Western media in general, incest is usually treated rather differently though, being a shorthand to show someone being completely morally decrepit
What gets me is how often sibling incest is portrayed as this sweet, star-crossed romance thing in Japanese media
That's true. I just meant the absolutely braindead season finale for the show was absolutely hilarious for me. Like watching that show fall apart was the most entertaining it had been in years.
Honestly eh. So incest isn't big in Japan. Which just leads me to think that this falls under the general misogyny of that society. And boy oh boy is a freak show. I mean considering whose been running that country and at whose behest. It probably fits. Plus it's like at the end stage of capitalism (as in a society that has successfully implemented capitalism as well as possible) and what you find there is a soulless abyss. Japan more than the rest of the world (although under capitalism we're all there to some degree) is a direction less society and profit just doesn't cut it. On the flip side they produce some seriously good but seriously depressing media. Stuff like land of the lustrous or technolyze.
Also the way your wrote this post up was really funny. Like it really captures the feeling of watching a piece of media fall apart. This was me when I read this manga called usagi drop. I literally couldn't believe it. I was genuinely shocked. This was well before I realized how ridiculous Japanese media can get.
