chains between different types aren't a "waste" because chains aren't just a mere boost. the ingame announcement and the wikia page state that "Chain represents special relationships between the daemons." like a friendship bond.

now as for this specific chain: now that we have the definition of chain, let's apply it to these two:

Book of 5 Rings is a book written by Musashi, so is normal for them to have a chain. both of them could have a chain for each other.

as for typing, not all chains will be for the same type. let's look here:

Book of 5 Rings is a book, so he(?) should be an anima, not a phantom or divina.

Musashi Miyamoto is a famous human figure, so he should not be an anima, and he's better as a divina than a phantom.
