S1eth said: I don't see how okamisty and Mokou simply appearing in the same picture makes this a Night Sparrow Love Tribute.
But it's obviously referencing it. I mean what other times do you see Mystia dressed up in her Lorelei outfit with Mokou in the same picture? Not very often.
I'm gonna have to agree with S1eth. Just because they are in the picture, doesn't mean it's a mitsumoto reference. Maybe if there was a bag of coal laying around that looked the same or if Mystia looked really flustered then maybe. The shop doesn't even look the same to me, to be honest.
