Akito Himenokouji is the male protagonist of the series, reuniting with his twin sister Akiko after six years apart and beginning a new chapter of cohabitation at St. Liliana Academy. By day, he fulfills his duties as a diligent student council member; by night, he crafts provocative light novels under a pseudonym to cover living expenses. Although he makes every effort to maintain proper boundaries with his sister—whose obsessive brother complex knows no limits—his naturally kind demeanor inevitably draws a colorful cast of girls into his orbit, turning his everyday life into an endless whirlwind of chaos.
