Looks like a Mashiro and Touko 4* pair, according to the text colours. The members' stars on the left must be in the gacha, and the members' stars on the right should be in the event.
I highly doubt Nanami will be the gacha 3*, since she had one in the last Monika event, but the pink-ish star on the right looks more of Tsukushi's colour, so I feel that'll be the case.
Then there's the attribute, which has to be pure. Tsukushi has to be a 2*, and any type but powerful. Rui's 3* has to be pure or happy.
That aside, I can't wait to see how the set'll be like!
