Who is the panty-masked villainess spreading obscenity in a country where even the mildest off-color musing can land you in jail?

When the student council president of the most elite public morals school in the country has a feeling that the lewd is coming from within the walls, she recruits Tanukichi, a recent transfer student, to her upstanding moral squad.

Little does she know he’s already been blackmailed by Ayame, her own vice president who is secretly the panty-masked bandit, into committing mass acts of public obscenity in the name of SOX—a brigade of sorts—dedicated to spreading the good news of being lewd.
