[R +18] Yosuga No Sora

Tragically orphaned by an automobile accident, the Kasugano twins travel to their grandparents' countryside residence via railcar, hoping to reconstruct the shards of a shattered life. With an uncertain future, Haruka Kasugano clings to memories of the past, hoping to find the strength he needs to protect his ailing sister. With a destiny irrevocably tied to that of another, Sora Kasugano clings to moments of the present, drawing comfort and security from the company of her brother. Two lonely souls so physically alike, yet spiritually divergent, unaware of the challenges these conflicting expectations will unveil in the days to come.

Characters:
Kasugano, Haruka [Main] - The protagonist of the series. With a gentle appearance and slim profile, in many ways Haruka is the spitting image of his twin sister, Sora. Personable and honest, he forges lasting friendships with remarkable ease.

Kasugano, Sora [Main] - The main heroine of the series, she is a quiet, fragile and reclusive girl, and fraternal twin sister to the main protagonist. Ill and frail since birth, Sora was denied the sort of independent life that many take for granted. Yet beneath Sora's angelic doll-like appearance lies a troublesome personality that’s prone to withdrawn laziness and demonstrates a rather severe lack of social graces.

Amatsume, Akira [Main] - She shares the same father of Kazuha, though Kazuha's mother does not like this, eventually convincing their father to disown her. Akira’s energetic liveliness is contagious to those around her, with an innocent personality that makes befriending the girl second nature.

Migiwa, Kazuha [Main] - The stunningly beautiful daughter of an influential magnate, Kazuha lives a cultured life that could be compared to that of a modern princesses. Sharp-minded and attentive to detail as a result of her parents' constant travels and long-distance liaisons, she learned from a young age to behave responsibly, as befitting her social standing.

Yorihime, Nao [Main] - Beautiful, intelligent and an excellent swimmer, Nao is Haruka's next-door neighbour and childhood friend. When the Kasugano twins last visited the area, their departure was particularly painful for Nao, who had grown quite close to Haruka, to the point of having sex with him on one occasion, about which she feels guilty. Upon their return, she attempts to rekindle their former close relationship.

Nogisaka, Motoka - Motoka is a college student struggling to make ends meet, working as a maid in the Migiwa Household to pay for her tuition expenses. While not ideally suited for household chores, her warm compassion and captivating personality offset these deficiencies.
