第 4 集: Sandalphon以發明協助學生，並接受Belphegor的建議以通過考試

4

Sandalphon (Diligence) chooses a student as her candidate and helps him study for an exam using her inventions and asking advice from Belphegor. Despite Sandalphon's machines and her own physical attractiveness giving him trouble to focus on his studies, the candidate ultimately, albeit barely, passes his exam. (Source: Wikipedia)
