Majin Tantei Nougami Neuro, Cuticle Tantei Inaba Recommendations
An uncomfortable mix of serious plot, weird magic protagonists, questionable gags, forced humour, oft-repeated catchphrases, and 00's art in a private detective setting.
Some crimes happen too I guess.
Both of the shows are shounen mystery anime. The only exception to their similarities is that Majin Tantei has less humor than Cuticle Tantei Inaba.
