I'm very shocked (in a good sense) to see this single performing well on the chart
9>10>11>7>6
Looks like this single will be making it to the top 10 (the last one was royal chocolate flush at #10) despite the early announcement of her upcoming album

i'm quite positive it will sell more 約束の翼 (currently her best selling post eighth world single)

this is a good sign for her upcoming album
