omgod, im so sorry orz

For that, i think it's only active during non-event days (?)

But either way, it's going to switch out between different courses and characters. From what i saw it rotated from each unit lesson to unit lesson, with only one character having the increased jewel drop rate. And the jewels go from Red -> Blue -> Yellow -> Red etc.

I think it's stated in the news, which lesson has the increased drop rate, but cant really tell which one it is unless there's been someone translating it
