Not sure about that. I do know they have a rivalry going on between each other which naturally makes them popular to ship together. Same reason that Asuka and Homura is popular too (probably anyway).
Sakazuki is a asshole, indeed, but he was more brave in his admiral fleet time than Sengoku (his talk with the Gorosei was my reason to use that frame)
Also, I FINALLY can past that damn panda. THANKS QwQ
I just finished watching LWA literally seconds ago. It was that episode when Akko helps Diana with that Cavendish's cerimony. It was a Diakko's subtext heaven.
That's why this image for me today just fits so damn well.
