Path of Training

I'm still undecided about what to get with this exchange ticket, but from what I've seen, Mizuki seems to have been significantly strengthened with Star Diffusion, so I'm thinking of prioritizing her. I haven't been able to advance her limit breaks much, so if I get her again from the next permanent exchange, I think she'll be able to reach 2 limit breaks and become strong... I have a feeling a dedicated boss will eventually appear, so I learned from Nadkrai that preparation is important.
