When I’m nervous, I point my feet in towards each other. This has to do with the fact that I’m naturally a bit pigeon-toed although, for the most part, one wouldn’t notice. Much like the Boston accent that I tried to rid myself of in third grade, my pigeon-toed stance is something that appears rarely. For those informed, as you are now, it says that I am ill-at-ease. For those uninformed, it more than likely belies discomfort, in spite of the fact that one seeing me may not know the full story of my stance.
We unknowingly inform others daily of our comfort levels, mood, and emotions through small physical indicators. Additionally, there are two different results that can be drawn from visible indicators, and Yuyushiki plays with them both.
Yuyushiki reminds me a bit of someone playing a game. They can only have so many members in their party, and they are constantly shuffling however many characters they have to fill the specific slots. Each combination of party members has a different dynamic and effect on how the game is played.
