Just putting this one out here (if this havent been talked about previously)

As the upcoming water tower is coming soon, remember that floor 8 (I think) have the 2 defense hime mission. Considering that there are only 2 non-SSR thunder defender hime (Perun and Kingu), if you havent gotten the 2 defender hime you need, you should consider taking Kingu for your SR miracle tix exchange.

However, if you think tower is irrelevant, just pick whoever you like.
