Dude, firstly we need to wait for Ayaka banner…..Also make sure you are near the 75 th wish before the start of Ayaka banner.. Once the banner starts proceed with the 75 th wish and continue till u get the 5 star character..
The 5 star character you receive would be 50 percent Ayaka and if your luck is so bad u might not get Ayaka and get another 5 star.
If you are so fixated still then u need another 75 wishes to get Ayaka.. ?? Which is difficult to get by the amount of promos u obtain in the game.. The only is to spend money and get it…or hope u get that in the first time.
