OniAi - S01

After losing their parents, siblings Akito and Akiko Himenokouji were separated and raised by different families for six years. Now reunited, they start living together-but Akiko’s feelings for her brother go beyond familial love, while Akito remains oblivious, seeing her only as a sister. Their quiet life is upended when three more girls-Anastasia Nasuhara, Arashi Nikaidou, and Ginbei Haruomi Sawatari-move into their apartment. With Akiko’s dream of living alone with Akito shattered, she now faces competition, as each of the girls has her own way of expressing affection for him. As they vie for his attention, their flirtatious and sometimes overly suggestive antics create a chaotic-and overwhelming-situation for Akito.
