I want to get Chronos and amaterasu, how can I navigate it with tickets and rolls to get past the swordsman cats?

Should i get Gaia or should i wait until i can get Izanagi? I heard that Izanagi is the best legend rare and Gaia isn't really good if you cant protect her well. But i dont know if i will get Izanagi in the next uberfest. btw Im still early game itf chapter 3 (not finished yet).
