Yeah, most probably it will be a special gacha featuring the top 3 most voted Flower Knights with increased drop rate. I've known Nutaku's FKG for a year to the point that I can mind-read what they're gonna do.
Waterlily? Isn't that the maid from the gacha?
You're asking for the Nutaku version or the DMM version? If it's Nutaku, then I think it's 18/4/2016.
Oh, just looked at your event list. No wonder you asked when was the launch date. The 1 year anniversary event should be THIS EVENT goddamnit! But then again, if we follow the release date........it will be during the next event. Kinda messed up.
I've always wanted to say this ever since the 1st popularity contest (Lechenaultia). Why can't Nutaku team up with DMM to get the artists to produce new artwork based on the top 3 in Nutaku? If they do that, then we'll be able to have something exclusive only to the Nutaku version like Bride Alpinia Now who would love that? Yes, I know, I know, it's Nutaku, what more can you expect? But seriously, if they really did this, everyone's gonna be super excited!
