Gakuen Shimai

Based on an original concept by Kino Hitoshi, this narrative follows Sousuke, an ordinary student at a school where sisters Arisa and Mika Nanase are celebrated as the most popular and attractive idols. Like his peers, he admires them from a distance, harboring a particular affection for Arisa despite the improbability of ever addressing her. The situation changes when Mika arranges a private meeting after classes, where both sisters inform Sousuke they have all become siblings. This development results from the marriage of their parents: Sousuke's adventurer father and the sisters' archaeologist mother, who met during a South American excavation. As the three now share a household, Sousuke faces new domestic challenges, including the need for discretion in his private habits to avoid discovery by his new sisters. The living arrangement introduces scenarios of intimate proximity, such as shared bathing between siblings, which may lead to unexpected forms of assistance or interaction.
