Hanzos are mercenary summons, meaning Nazarick had a limited supply of their data. Now that they've run out, they would need to spend a lot of gold to obtain further Hanzo data.

>Though the library of Nazarick contained data on various types of monsters, it did not contain the data of every single type of monster from Yggdrasil. Some monster’s data were of limited use too. For example, they had already exhausted their supply of data on Hanzos and the library did not contain any data for the creation of Eight-Edge Assassins.

This is from volume 14 chapter 1.
