No, Reimu is saying 11/11 is supposed to be "pocky day" then yukkuri says she'll make a "yukkuri day" too.
And she stretches to make a one, so 11/11 is yukkuri day.
Since 11/11 looks like 4 yukkuri placed parallel to each other, it's proposed to be "Yukkuri Day".Eeh~ which day (is it on)?Yu~ Then there'd be yukkuri day too!Yu? Why?11/11 is supposed to be the "Pocky Day"It looks like 4 pieces of Pocky placed parallel to each other.
