Imagine if we got a spin off of Ranpo and Poe (or dare i say it? Ranpoe) and it was in the beast artstyle.
Have it be a noir style detective story were they get to be detectives, especially Poe since I think his intelligence and skill as a detective is second only to Ranpo (I'm fairly certain he's canonically the only person Ranpo ever had to try against) is neglected so I think he should be given a chance to shine. Perhaps it could be set in America so we get a look at how ability users function over there, as our only idea is the guild and I suspect they're an outlier. The setting of America could also work to let Poe shine as it's home turf and the difference may throw Ranpo of just enough that he doesn't seem so omniscient.
Maybe even a short series were they travel around the world or even just Japan solving mysteries and other shenanigans
