Shiga

Serving as Rinka's dedicated assistant, this easily flustered character plays a crucial role in navigating the school's underground magazine trade. She is frequently recruited by Rinka to act as a moral compass, specifically tasked with evaluating the level of indecency found in the various publications brought in by the boys. Though often overwhelmed by the scandalous content, her involvement remains vital to Rinka's ongoing investigations and management of the group's secret activities.
