Also people that say negative things about this series pisses me off. No matter where I go, even the most yuri friendly sites have these negative people saying the most inmature things ever just because of the fucking incest incident that happened in the first ova. That's in the past people, not even Aaya wanted to be part of it!! In the 2nd ova after Aaya found out her brother died and she had to move out (probably because her parents aren't even in Japan and was dependent on her brother) she fell into a deep depression and felt desperate to be with Kii-chan cause she knew her time was running out. And that's why it leads to what happened in the second ova, the kidnapping and rape. Yeah it sounds fucked up. I know it does. But she did it cause she didn't wanted to leave things as they were (Kii-chan avoiding Aaya). That type of ending would've left off people feeling too salty, and when you think about it realistically it's just bitter as fuck too. Imaging the anime just finishing that Aaya just left without doing anything to see Kii-chan and that Kii-chan didn't wanted to see Aaya at all and some other shit happens that involves deep depression and regrets. Would you had prefer that!? FUCK NO! I would've raged hard because of that, I mean anyone would! The creator of the anime (WHO BY THE WAY DID THIS PROJECT BY HIMSELF) is an independent guy who one day just thought "hey, I'll make a yuri anime by myself cause I want to". So cut him some slack cause no one deserves to insult his work that got him recognised around the world for it. Also I didn't make this shit up. I researched unlike some that still critize this.
PS. The sex may seem pointless but THEY ARE TEENAGERS! When teens fall in love what is it that they do? HAVE SEX! AND LOTS OF IT! This anime is meant to be ecchi so yeah there's lots of sex, don't be so butthurt about it. Not every yuri is sweet and innocent.
