One question though, if let's say Mint won the popularity contest. And I have one Mint in my party, does she gets turn into 6* after the event, meaning I gain a 6* Mint automatically?
All the NO! in the World.
She would be an entirly new character you can roll in the Gacha for. That goes for every character.
