Kongou, you silly. If you're claiming as the thirteenth of their class, might as well claim yourself as Uruuzuki (the intercalary month).
I'd be really surprised if IJN Uruuzuki was a real thing, tho.
I'm just imagining a little destroyer flotilla attacking with Kongou dutifully bringing up the rear.
"Destroyers charging in to attack us ... WHAT THE HELL?!!"
Mutsuki class 13th ship, Kongou-desu!Nagatsuki onee-sama, please take good care of me~βAh...
So it's like that...What kind of imitation is this...?The clothes were made for me by the Fairies-san in one night!Were you surprised?
Today is April Fools!
