"OniAi" is the shorthand name for the 12 episode harem anime series known as "Onii-chan dakedo Ai sae Areba Kankeinai yo ne!" which means "As Long as There's Love, It Doesn't Matter If He is My Brother, Right!" OniAi is based off its source manga (or Japanese comic book), is directed by Keiichir? Kawaguchi, is produced by Studio Silver Link, and licensed for American distribution by Funimation. The plot of this anime revolves around twin siblings Akito and Akiko Himinekoji. The high-school-age brother and sister, who have lived apart for six years from the moment their parents died, are reunited when Akiko decides she wants to return to some sense of familial bonding. However, as time passes, Akiko's feelings for her brother intensify beyond what is socially acceptable; feelings which are not even reciprocated by Akito who only cares for her like an older brother does for his little sister. Despite the show's incestuous title and undertone, it's eventually revealed that Akito is actually adopted but kept the information a secret to taunt Akiko. In addition to Akiko, several other girls wind up vying for the closest place within Akito's heart. From the Russo-American Student Council Vice-President, Anastasia Nasuhara, who always seems to do slightly better than Akiko; to Akito's tomboy of a childhood friend, Ginbei Haruomi Sawatari; to the seemingly perfect, sexually aggressive, katana-toting, Student Council President Arashi Nikaido (later revealed to be related to Akito and only supporting him instead of seducing him); to the 12 year old child prodigy, Arisa Takanomiya, who prefers to display her emotions through her facial expressions rather than through her words.
