Koisuru Otome to Shugo no Tate: Bara no Seibo

Koisuru Otome to Shugo no Tate: Bara no Seibo is a Japanese adult visual novel and the sequel to Koisuru Otome to Shugo no Tate: The Code Name is "SHIELD 9". Both games feature a crossdressing protagonist named Shuuji Kisaragi who infiltrates all-girls' schools in order to protect its students on the behalf of a personal security organization.

Since the events of the previous game, Shuuji has completed several more "crossdressing infiltration" assignments for Aigis Security and is considering quitting while he is ahead. Before he can, however, he is given one last assignment: to infiltrate another all-girls school and get successfully elected as the student council president two months later. Although Shuuji has doubts that he can complete the mission in such a short time frame, he accepts the challenge, resuming the identity of Taeko Yamada to carry it out.

The player makes decisions throughout the game which may cause the story to branch into different routes and result in different endings. The Windows version includes scenes with sexual content which were omitted from the console versions.
