>>26415403Believe what you want, it's the only plausible explanation for Renko's popularity flaring upwards out of nowhere for no reason while both Maribel and Sumireko got stuck behind.
If Maribel's popularity had increased too you could have handwaved it as Sumireko making people interested in the Secret Sealing Club's activities (the music CDs) and if Sumireko's popularity had increased instead you could have handwaved it as some sort of Usami Sisters thing. But neither happened, it was just Renko.
And it's so likely to be what happened that even someone who is actually Japanese agrees, hence that pic of Sumi instructing people on how to spell her name.
