Tập 4: Sandalphon giúp một học sinh bằng các phát minh và lời khuyên của Belphegor để vượt qua kỳ thi

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)
