Sena is Akagi Kouhei's little sister. While at first she pretends otherwise, Sena is a fujoshi, or "rotten woman" (a woman who loves yaoi). She often fantasizes about it; the idea of her brother and Kyousuke having a homosexual relationship is particularly pleasing to her. While she denies it, she is a brocon and has feelings for her brother. It is also shown that her brother cares deeply for her and, as Kyousuke says, is "a total siscon."<br /> <br />
