Just in, Namitamaki73.net just discovered that Oricon isn't showing what the single has charted or sold because it's only an anticipation single for the album (it's not it's own single... its like an advertisement) but based on other charting sites the single has an average charting of
#7 or #6
and has so far sold 30,000.
Once the album is released, Omoide Ni Naru No? 's ranking will show on Oricon
