Sentai Filmworks made a couple announcements earlier today at its Otakon 2012 panel, leading with the addition of Nakaimo to its anime lineup. The licensor also dated its Blu-ray release of Studio Ghibli's beautiful but tragic 1988 Grave of the Fireflies film for November 12.
Crunchyroll started streaming Nakaimo ~ My Little Sister is Among Them! on July 18. Based on Hajime Taguchi's light novel series, the show follows Shougo Mikadono, a boy who transfers to a school his future wife is said to also be attending. In accordance with his father's will, he must find his destined life partner, but there's a catch: As the title says, his little sister is among them and he doesn't know what she looks like! Quite the pickle, right?
