Basically, admiral seeing that Akebono has been calling him kuso teitoku all these time, decides to tease her by telling she's kuso kawaii.

I'd add in the notes but I don't have a very good idea on how to get it done without getting it lost in translation. Closest I can think of are "fucking admiral" and "fucking cute" in place of those two, but I'm not sure if it's appropriate.

Seems like an appropriate time to use the term disgustingly adorable.

Shittyly cute?

Took a stab at it. Feel free to change it if you see fit.
