If you think about, it can only be Fumizuki because Satsuki, who actually got a Kai Ni, and Fumizuki can both upgrade the 25mm Single AA Gun into the 25mm Twin AA Gun, and upgrade that into the 25mm Triplet AA Gun.

That is not a quiencidence(?), no other Mustuki class DD can do that, EXCEPT Satsuki and Fumizuki, which deffinetly says something.
