So Obako got added to the Rainbow Medal shop, I think she's kinda meh for a brand new unit ? I rather spend my medals on support girls and Pavonia.
The support dry is real, after spending some time trying to find good buff girls from 5* RG, I gave up because there's a lot of them but most of them are useless.
Rabbit's Foot looks like a good RM unit: https://flowerknight.fandom.com/wiki/Rabbit%27s_Foot
I should have picked Crepis, she looks like a really good support, but I guess it's too late.
But well Pavonia will likely be in the next rotation, finally!
