Nope. Just 4* for the moment. But there is still 27roll to do. It should be possible to get something.
Edit:
Okay the event girl, Gooseberry, is not that bad after promotion with -20% ATK for every enemy, skill act and ATK buff. Not awesome but still usable as debuff unit.
And Rose Diana is... not that good. At all. Skill Rate, Skill damages, ATK buff and... Solar Blast. Just that. I forgot about her Solar Blast ability. And they missed a chance to make a great Slice SB girl.
