お姉ちゃんが来た
The story revolves around Tomoya Mizuhara, a 13-year-old boy who suddenly gains a big sister when his father remarries. 17-year-old Ichika is a little strange, and her affection for Tomoya is rather overwhelming, if not scary. On top of things, Ichika's friend Ruri is the ultimate sadist. Then there is Ichika's big-breasted quarter-Japanese friend Marina. (Source: ANN)
A 13-year-old boy gains a 17-year-old stepsister whose intense, boundary-crossing affection drives most of the show's comedy, alongside a sadistic friend and a fanservice-heavy supporting cast. Expect persistent sexual humor, suggestive situations, and a premise built on an underage protagonist being pursued by an older stepsister, all played lightly but pervasively.
