Yosuga no Sora
Alternate title: Sky of Connection
Young twin siblings, Haruka and Sora Kasugano, return to the countryside of their youth after a tragic auto accident kills their parents. While Sora generally keeps to herself, Haruka strikes up many friendships with new and old acquaintances. However, Haruka is hiding his true feelings for someone very close to him, because that particular relationship is strictly forbidden.
First of all, I must warn everyone that this series has a very mature theme and is not for anyone under the age of 15. It is a harem-type, romance series that carries a good deal of nudity and sexual content. Not sure why they don't consider it Hentai, but for some reason it's not.
Yosuga no Sora began airing in Japan on October 4, 2010 and contained 12 episodes. Each episode consisted of 22 minutes of the original feature, and then a cute 3 minute chibi bonus. The original feature episodes depict a series of Arcs portraying Haruka's relationships. Those old enough to appreciate this mature themed series will enjoy the beautiful character designs and the reasonably satisfying ending.
