Akitoshi's stepsister Midori comes to him with a problem: their younger stepsister Ichigo is struggling badly with her exams and needs a tutor. Akitoshi steps up. When he arrives, it becomes immediately clear that Ichigo has absolutely no interest in studying — she just wants to play video games. The challenge for Akitoshi is figuring out how to actually motivate her to do the work. This may be more complicated than a simple addiction.
