Sword PA(alternate one)

[Aristrodrim]

Does anybody know which mission gives the alternate sword PA? Ive heard that you have to get an S-rank on a mmission but i dont know which one.

are you talking about online or offline?

As far as I know it's only obtainable offline. You just have to S rank missions with Leo in your party until he gives it to you.
