Yukari Takeba

Hey, who are you?!
She reached for the evoker to wake the man up.

Yukari realizing what a friend really means to her is especially shown when her Social Link is maxed, as she hangs out with her fellow female SEES members and encourages Mitsuru to move on from the past. Yukari despises the Dark Hour, and likens being a Persona-user to trading innocence for power, since you can no longer turn away from the things you don't want to see. As a result, she considers being conscious during the Dark Hour to be a curse rather than a blessing, and so is shocked by Strega's willingness to keep it active just because it makes them feel special, calling them "crazy." She has made it her goal to eliminate the Dark Hour no matter what and fulfill her father's dying wish, a desire that only strengthens after receiving her father's true message (the other one had been edited by Ikutsuki), which triggers the evolution of her Persona.
However, while Yukari's love for her father reaches the point of idolization, she has a toxic relationship with her mother, who threw herself at random men as a coping mechanism against her husband's death. Eventually, Yukari decided she was better off living alone, doing so for 3 years before coming to the S.E.E.S. dorm. The two rarely talk, and when they do, their conversations are straight to the point at best and even outright antagonistic at worst. This in turn has made Yukari self-reliant and responsible, but also cold and aloof in some regard as well.
Yukari has phasmophobia (a fear of ghosts), which Junpei, Akihiko, Ryoji Mochizuki (and sometimes both protagonists) often take advantage of by intentionally spooking her or telling her ghost stories to agitate her to their amusement. Yukari's phasmophobia can be seen as being symbolic of her fear of death. Yukari has an extreme fear of death to the point where she initially has difficulty using her Evoker.
