Trish Una

Trish Una is a fictional character from Part V: Vento Aureo.

About
Trish is one of the heroes of Vento Aureo and is the only female protagonist in Bruno's gang.

She is the daughter to their boss, Diavolo.

She was living a normal life before she found out who her father was. From then on, she was on the run to meet her father. When she finally got to her father, she learned that he actually wanted to kill her, so all his ties with the past would be erased, including the people related to him.

Vento Aureo
Trish is introduced as Passione's boss' daughter that is put under the eye of Polpo's replacement operative, Bruno Buccellati and his gang members Narancia Ghirga, Pannacotta Fugo, Guido Mista, Leone Abbachio and Giorno Giovanna. Because of the mission, she found herself being pursued by fellow Passione members and assassins.

She awakens her stand powers on the plane to Sardinia when she was being attacked by Notorious B.I.G., and makes use of her power to retrieve the ladybug that Giorno transformed into his hand in order to restore his Stand's abilities. With her help, the group is able to crash land safely through the plane's cabin and force Notorious B.I.G. to crash into the sea.

Trivia

 * She loses her boot and is never shown getting it replacement after it was eaten by Notorious B.I.G. so Hirohiko Araki must have forgotten this or become tired drawing her without her right boot.
