I don't even know
THE ONLY TIME YUKIMURA SMILES IN THE WHOLE EPISODE and it's when he's being incredibly heterosexual for Kanetsugu
On that note, Kanetsugu's "OMG IS IT YUKIMURA" face is pretty adorable in and of itself.
I love this show even if I can't understand it. It makes me happy in my heart.
