The Hakata-go ("Kokura-go" in this drawing in reference to DreJour winning the Kokura Daishoten) is pretty much a running gag in Doudeshou with how grueling the 12 hour or so journey was for the cast and crew.
Honestly, this boombox (doombox?) doesn't suit a band called Wolves of Russ. Bearing as it does the traits of all 4 chaos gods, it should've been made for a band calling itself The Chord Bearers.
