神様のいうとおりッ　くじびきAI-BIKIスクランブル

There is a weird class at our school where people from first to third grade are gathered for some purpose. I never expected to have anything to do with it, but here I am, a new class member surrounded by seven girls. As it turns out, there is a mysterious social study lesson where relationships are determined with a lottery. The theme of first lesson is "slave".
