We’re introduced to another character, Furuhonya, a sort of antique bookseller whose namedropping of authors and books are indeed based on real life and while he didn’t have much role in the whole episode he did bring a magic book with him.
The seal of which is broken by Inaba unknowingly. Considering the arc is divided into two parts, we should get a proper explanation for it.
However, whatever the explanation is, it boggles me that Inaba is gifted with healing power and doing stuff like breaking seals. On top of that, Inaba and his friend got involved in a gang fight.
Situations like this makes a story about an apartment filled with Youkai more unrealistic than it already is. Regardless of how unrealistic or runaway a plot is, there should be some basis in reality, something to make it believable.
Elegant Youkai Apartment fails to do so and a large part of the fault lies in the direction. The transitions scenes and the setting is always too abrupt.
