Onee-chan ga Kita

Thirteen-year-old Tomoya Mizuhara’s life takes an unexpected turn when his father’s sudden remarriage lands him with a brand-new older sister. At seventeen, Ichika is bright, energetic, and utterly devoted to her new younger brother—perhaps a little too devoted. Her affection is less a gentle sibling bond and more an overwhelming force of nature, teetering on the edge of terrifying. For a boy who was perfectly content as an only child, navigating Ichika’s intense, unpredictable love becomes a daily trial that offers him no room for quiet solitude. As if one eccentric sister weren’t enough, Tomoya soon finds himself entangled in Ichika’s equally unusual social circle. There is Ruri, Ichika’s close friend, whose sweet smile masks a personality that is relentlessly sadistic and delights in Tomoya’s discomfort. Rounding out the chaos is Marina, a quarter-Russian beauty whose striking looks are complemented by a rather generous figure, adding yet another layer of awkwardness to Tomoya’s already complicated days. Surrounded by these larger-than-life girls, the young boy must learn to survive the relentless onslaught of affection, teasing, and absurdity that now defines his daily existence, all while wondering if he will ever get a moment of peace again.
