Sorry I can't read Japanese, but why are there 2 versions of Guriri's with different NicoNico links?
Just because she covered it twice? o.o
And on a side note, the sm7957120 is uploaded by kuripurin who did the encode there, and the sm12346946 features a PV also.
Oh I see. Thanks for the explanation (I just found it puzzling there was no note or description explaining the difference here)! ;)
What do you think?
