100Geisha
Lets you recruit more geisha by increasing cap of all vanilla agents to 100 and getting rid of unique building caps for all top tier buildings. So you could build a Infamous Mizu Shobai District, any legendary you want and a nanban Quarter in every providence.
I also tested using the following mods:
expanded.pack,
TimeWarp.pack
TimeWarpRecruiterOtomo.pack
TimeWarpNormalRange.pack
TimeWarpNormalRangeOp.pack
3SkillPointsPerLevelAgents.pack,
general_extra_points.pack,
MoreHonor.pack
TraitMod.pack
BuildingMod.pack
TechaNdTrees.pack
OpAncillarys.pack/AncillaryCheat.pack
