Big Sister's Here!

Finished

お姉ちゃんが来た

Thirteen-year-old Tomoya Mizuhara's life takes an unexpected turn when his father remarries. Suddenly, he gains a 17-year-old stepsister named Ichika. While Tomoya hopes for a normal family life, he quickly discovers that his new big sister is a little strange, and her affection for him is overwhelmingly intense, often crossing into unsettling territory.

Tomoya's attempts to navigate this new dynamic are further complicated by Ichika's friends. Ruri, who frequently visits, reveals herself to be a gleeful sadist, finding amusement in Tomoya's discomfort. Meanwhile, Marina, Ichika's quarter-Russian friend, adds her own brand of chaotic energy to the mix. Together, they ensure Tomoya's daily life is anything but peaceful.
