Waiting for her to be implemented and saving every gem i can for her.

Until then i guess Orchid Wylder is the favourite out of the ones i have.

By the time she arrives there will be too many rainbows and you know its %0.5 chance... But i read some stuff in upgrade notes that dmm did an event which if you spend 50 gems you get a select your waifu ticket, dunno if it includes rainbow units.
