These stories only work with MCs like him. She is only as powerful as he allows her to be. Like Teasing Master Takagi-san. Takagi appears to be smart and cunning only because Nishikata is borderline retarded.
I'll try this one solely because Hiiragi-san was so good, but yeah this one is a little generic to start with. But it's only the first chapter so hopefully it'll improve...?
