Well, that resolved quickly. I'm not sure about the pacing in the middle part, but I liked how Amane summed it up on the last page. But it feels like Ryou didn't really get a say in this. Or did the prospect of two girlfriends when Nina and Amane are hugging just sell her on the idea?
One things that might have gotten lost in the English translation is that D.Va says that she is the person who loves Mercy most (out of the whole bunch?) instead of Mercy being the person who D.Va loves most. It's not that much of a difference, but I kind of like it more. I think it makes her look a bit more proactive and matches the strip better.
Kumichou's Umi's facial expressions of her strict samurai persona just before she switches to doting mode or when she and Kotori are fighting are one of a kind. I can't put my finger on it, but her :< face is somehow charming and cute.
I was a bit puzzled by that remark, too. I had thought that the multi-chapter volume about them back in school had already established them as lovers. But oh well, you can always chalk it up to the last few vestiges of tsun left in Maki.
