The pun in this comic is because in Starlight Stage, you can't use the word "pASSion" (Thus, Kaede's "P*ion" pun).

So it has the same kind of dumb censoring rules as the English version of School Idol Festival, which censored "ho" so you can't even use "HOnoka"'s name?

can't even use Sachiko's name too ;__;
