He listed Cupid in his post he made a day ago. The hime you can get from this event. So I'm sure they have some time in the event already, the question is how much.

His biggest problem right now is his base stats, based off his post of him saying his eidolons are 0~1 star and listing Lilims and Disasters. Getting a proper eidolon grid is far more important than getting Vine, who I wouldn't be surprise would only be trouble in his current state due to its incredibly low stats.
