Ranpo Kitan is very stylistic, and accordingly it has a lot of artistic symbolism and a beautiful soundtrack which perfectly fits the mood of the show. The core idea that Ranpo Kitan seems to be trying to portray is that reality seems absurd to us but that's just because we fail to account for the infinite factors influencing us. As a determinist and someone interested in the irrationality of human psychology I found the exploration of this premise very interesting. Since the show is trying to depict reality as something absurd you'll find a lot strange and eccentric characters whose quirks seems pointless. I don't think the quirks are pointless though- I think they are all there to contribute to the idea I outlined above. Why does the new teacher act like an 11 year old and dress like a lolita? You won't find an answer in the show, but that's kind of the point: if we are to believe that all of the past influences all of the future then it'd be silly to think we'd understand our present since we are not omniscient beings who know all of the past.
Oh, plus there's an adorable trap as the main character. I understand many people don't like traps, which respect, so you can think of this as a warning if you're one of those people. But dang, I have weak spot for them.
