E-EEEEH?! IS CHALLENGE LIVE DEAD OR NOT?! (Idk anymore ;-;)
Ok, full Popipa (yay!!). The text is yellow and reddish-pink but it looks like Rimi should be the other 4*, since it makes no sense for Kasumi to be a 4* again. We can also see the size of the stars, and Saaya's and Rimi's are the biggest.
I also feel we're gonna get a gacha 2* again, since Arisa has the only star that is mid-size, which means she should be a 3*
Then there's the event attribute, which should be happy. I think Kasumi will be in the gacha (cause her last happy 2* was during 1st Anni), and Tae's 2* will be in the event, also happy. Arisa's 3* should be pure
