Drafting Overview:
Kyousuke Kousaka, an ordinary high school boy, brings his younger sister Kirino home following her return from a special track and field camp in America. As Kirino reintegrates into her social circles and begins to get her life back to normal while surrounded by her friends, a tension develops between the siblings. Kyousuke finds himself unhappy with Kirino's current attitude toward him. Despite their previous attempts to reconnect through her secret otaku hobby, Kirino has begun ignoring him since her arrival. This behavior causes their relationship to revert to the way it had been a year earlier. While Kirino is an overachieving sister, the dynamic between the 17-year-old Kyousuke and his 14-year-old sister becomes strained due to this sudden emotional distance. The season focuses on this shift in their relationship as Kirino focuses on her friends and her return to normalcy, leaving Kyousuke to deal with the regression of their bond.
