I fell in love in this manga almost a year ago when I saw it on Mangafox. This anime seems to be following the manga closely and doing a decent job adapting it. All I can say is, this was just as assume as the manga, go watch it now.
BTW: Meat >>> Imouto > Rika > Yukimura > trash> Maria >>> Impassable wall >>>> Yozora
