I've actually known of Neuro for a good while, as the title character is a playable fighter in the Jump crossover game Jump Ultimate Stars on Nintendo DS. I was curious about the series because of the oddity of his moveset, but either it wasn't translated online yet, or otherwise I hadn't yet gotten into the habit of reading manga on the Internet. Years later, I would see hype for Assassination Classroom, and would eventually buy the first two volumes, which unfortunately at the time I didn't care too strongly for. More years would pass, and Matsui's Nige Jōzu no Wakagimi would begin serialization in Weekly Jump, translated for Shueisha's Manga Plus app almost as soon as the print magazine released in Japan every week, and I would start following it as I did every manga that began after I started using the app (around the beginning of Ayakashi Triangle...). It would quickly become one of my favorite current series, partly because of some crazy visuals around villain characters, and I would often see people make comparisons to Matsui's roots in Neuro, leading me to eventually start reading this manga in earnest (as well as inspiring me to soon give AssClass a second chance!).
Majin Tantei Nōgami Neuro is on its surface a paranormal detective manga, but I think it's ultimately an absurdist gag comedy. So far, the mysteries have been pretty interesting, but they're usually wrapped up fast enough that the reader doesn't get too much time to dwell on the facts and come up with his own solution, and indeed a lot of Neuro's deduction occurs "in the moment," without the reader being able to see clues before they are revealed as evidence. But I don't think any "failings" as a mystery manga matter very much at all, since the series is propelled by Neuro's own wackiness, including his constant abuse of Yako, unwilling participant in his efforts, as well as some horrific visuals with Neuro's detective tools or the way culprits contort their faces upon being called out. Indeed, quite a lot of what I enjoy about this manga is in the way it reminds me of Matsui's current manga, which is perhaps a backward way of viewing things, as I'm sure Matsui's intent with horror elements in Elusive Samurai was to call back to Neuro art-direction for longtime fans. But... whatever! This shit's cool! And hilarious!
