A month after the Jim Adamworth incident, Norman and his four Unlaw settle into their new lives at the Elementary Detective Agency. However, just because life at home is peaceful doesn’t mean the city of Bardium has gotten any less chaotic. Lonsday and Eltiel team up to take down the Mad Bomber, and along the way, discover the existence of anti-Unlaw weapons. Meanwhile, Clareth and Shizuku head to Evergrace Academy to investigate the mystery of the murderous Banshee. When the dust settles, they come to realize these cases are more connected than they’d previously assumed!
