Sena Akagi

As the younger sister of Akagi Kouhei, this aspiring programmer hides a secret passion for yaoi fantasies, often imagining romantic connections between her brother and Kyousuke. Despite her "fujoshi" interests, she harbors a deep, sibling-centric devotion to Kouhei. A member of the Computer Research Club, she famously reunited with Kuroneko to fix a bug-ridden game project. Through this collaboration, she helped the lonely Kuroneko form her first meaningful high school friendship, bridging a gap in the club's social circle.
