Ranko really makes me want to start punting babies off of the tops of skyscrapers or something. She's annoying as hell. I'm like, "That's your COUSIN. Even if Rea never existed, you STILL couldn't tap that." I know her reasoning behind it story-wise (I got curious and read most of the manga in one night), but still! And I don't care how yummy her breasts may be!
Unless she's just trolling to the max because she has nothing better to do.
