Wait a second... INT Garupa is currently going through Message for You, which is the last Garupa event for the 1st Season year of Bandori. This then smoothly transitions into Backstage Pass 2 and the anniversary, the start of 2nd Season in Garupa.

...Except INT's anniversary is a month later. Which means Backstage Pass 2 should happen a month later. And INT's out of 1st Season events. What are they gonna do? Kick the new season out of the anniversary celebration? Stay in 1st Season until the anniversary and move events forward? That'd make no sense if they don't explain the 'one year forward'.
