I was going through all the cards, so I started trying to guess what four stars might be in the limited New Year's event this year on Jp. After looking at the amount of limited four stars every character had, I conclude that Ako, Maya, and Tomoe do not have a limited 4*.
Since Maya was already a member in the New Year's event two years ago in Jp, I think we'll get a Udagawa Sister New Year's event this year.
Just some guesses
What do you think?
Edit: I accidentally said Twin's New Years, I didn't mean that. Ako and Tomoe aren't twins LOL
