The male Xunlai Agents allow you to add access to the materials storage upgrade, in addition to providing the standard Xunlai services. They differ from the standard agents in that they display an initial dialog before displaying your storage account. Just as each PvE character must pay separately to access storage, so too must each character purchase storage upgrades separately. PvP characters gain access to storage upgrades as soon as any roleplaying character on the account purchases it. For further details, see Xunlai Agent and Vault Box.
