It seems that you can actually get the same retainer twice. Especially with the monk’s monkey. I have gotten it 3 times before.

The Daimyo gets special Legendary Retainers that are pretty rare and so far aren’t available for anyone else. So either don’t level the Heir till the old man dies or bump him off quickly to allow the heir to get these retainers and not the standard general’s retainers. Also the only way to get admiral retainers is by being an admiral. I have not uploaded the admiral ones yet, but probably will under an admiral tab.
