Ah, there also 1 thing I need to address bout Emperium. Although Ryuuji doesn't care if the<strong>Customers</strong>calling the slaves degrading names. The<strong>employees</strong>aren't, be it to the "corporate slaves" or the ones belonging to a customer. The former because the employees should be better and above such name calling or if they are to do that, it should be done with more class than that.  They are afterall employee of a high class department store, not some roadside market (calling the slaves as "you" or "slave" are acceptable "cunt" or "slut" isn't). The latter because it require permission from the owner (some owner like Darya will most likely take offense to that since the employee effectively jumping over their authority as the owner).
