Started playing the English version February 4th, 2018, and the Japanese version March 16th, 2018. I only have those two accounts, and I never rerolled. I'm free to play and have no plans to change that.
After some consideration, and based on which URs I've gotten, my EN account is 2nd year based (9/6 2nd year Smile center), and my JP account is 1st year based (9/6 1st year Cool center).
My EN account urgently needs friends with New Years Umi (12% cool as pure + 2nd year 6% pure). If you have her, PLEASE add my EN account!
