The staff for the Spy Classroom anime has announced that the series is getting a second season that is scheduled to premiere in July 2023.
The anime is described as:
Conflict-ravaged nations now deploy covert operatives instead of missiles. Lily is recruited into spy-training… but her practical skills are absolutely abysmal. Desperate to pass, she leaps at the chance to join the mysterious “Tomoshibi” team. Too bad the team is filled with even more hopeless spies. Together they must conquer the Impossible Mission and best their genius instructor, but the true purpose behind their classroom is more harrowing than they can imagine.
The Spy Classroom anime premiered in Japan on January 5, 2023, and HIDIVE simulcast the anime as it aired.
