I'm starting to like Kongou because she is able to get along with everyone in the fleet.
I kind of have the same feeling about her and also Akagi. The later seems similiar in that she never seems to fight seriously with anyone and when she gets any character beyond 'lol piggyly-wiggly' seems to get along with everyone and just be nice and really likeable in general.
Kongou is the one that is openly going after the Admiral. Tenryuu is is a 2nd place though, as how the fandom is potrayed them(although Kongou's in game lines really help with that)
