Karera Sakunami

Karera is introduced as a mysterious woman who lures Jousuke into a back alley, having mistook him for another person. She is revealed to have some familiarity with Yoshikage Kira and presumably the unknown person behind Jousuke's other half. She's eventually convinced that Josuke was the one she mistook him for after he uses his stand to obtain her name through the card in her back pocket wallet. After the exchange, she borrows money from him and swindles a free meal from a yakitori shop by somehow producing a hair from a tsukune using what Jousuke assumes to be a stand ability
