>>280496656She was always a weeb
The reason the entire series happens is because she's a weeb and wanted her Japanese anime high school experience
I'm not kidding, it's canon
One of her brother's servants, Souji Okita, yes that Souji Okita,tells her about how Japan is so cool
So she starts loving Japan and decides she wants to go to high school there with her best friends Sona and Akeno
So her family buys the fucking school, she gets an entire building for her Occult club while Sona is student council president
Then she decides that the school needs to be co-ed because otherwise Kiba couldn't go to school with her.
And because a school with beauties with big tits is going to allow guys and not just girls anymore, Issei decides to enroll because of his harem dream
THE ENTIRE SERIES HAPPENS BECAUSE RIAS IS A WEEB
It's not just a cute quirk of her character, it's the reason behind everything
