Yes, Minister is the only other show I know that uses the second-in-command as a leading anti-hero.
In Hozuki no Reitetsu, the writers emphasize the details of mythology rather than the plot, characters, or jokes.
It’s more like an intellectual lecture than a situation comedy, and that’s exactly why I want more shows like this.
It reminds me a bit of Yondemasu yo, Azazel san. Both shows try to emphasize some realistic occult details, and both shows are very cynically humorous.
