Hisamoto was appointed to Iron wall town. When he reached the town there was no wall to the town, he felt awkward and thought, 'where is the wall? Which idiot keeps a name which doesn't suit the thing?'
The name iron wall came because even without a wall, never a life lost in the beast wave from that town, so they named the town itself as Iron wall. As to represent that no beast could enter the town.
There were few alchemists who had their own shops in Nilu kingdom by that time but soon everyone met with some kind of accident and died, so the fragrance pill association purchased those shops for low cost and named them with association name.
There were no restrictions for them in doing illegal stuff just because they were selling pills at low cost to the royal family and army. Nilu kingdom had 4 states. 1st state had the capital city, 2nd state had Plexus academy, in 3rd state Iron wall and Seshi towns were situated and 4th state had the Sword path sect.
